Since you clearly can’t be relied on for headphone reviews, I’m seriously doubting all your reviews now.
Are there any tests you think we could improve? And if so, do you have any suggestions we can implement to better our over-ear recommendations? We would appreciate your feedback on this issue.
Are you sure your testing was accurate? The frequency response of the Quad’s is worse than the Triple’s, which are less than half the price. However, ever review I’ve read/seen comparing the two have unanimously stated that the Quad’s are no doubt better (sounding almost as good as 2x it’s price).
Yes, we are pretty confident of our frequency response results for the Quad and the Triple, especially since we measure each headphone 5 times.
The reason for the Triple getting a better score is that its frequency response is closer to the response that we consider neutral. Our target response is loosely based on the Harman target response for headphones, and compared to that, the Quad sounds quite muddy. This was also confirmed in our listening tests. Ideally, all headphones should sound more or less neutral, and therefore have the same frequency response.
Follow up on my other question, if you are going to make a gaming recommendations section, then you should specify whether or not the headphones/headset are for competitive or for fun because if you are going for competitive, bass almost gets kicked out of a metaphorical window. Competitive headphones end up having a superb combination of imaging and soundstage with very little bass. Bass blocks out footsteps or amplifies them so much that you can't tell where the footsteps are coming from. This isn't the case with all headphones but as a generalization, this is true. Fun headphones make the game enjoyable but probably won't be very good for competitive gaming.
Something to think about.
Good question. At the moment our philosophy is that a good gaming headset should also be a good music listening headphone, so we are treating the sound quality part similar to our critical listening usage rating. But we will consider accommodating for the scenario you mentioned, if possible.
According to this, these shouldn't be praised for gaming due to their lackluster imaging and soundstage, yet are. Is this how the gaming recommendations are going to work? Or is there still some kinks to work out?
Since we have just launched our gaming category, there are still improvements that need to be done to our tests and scoring. Our current plan is to do it probably in a couple of months, once we have gathered more data from our gaming headsets.

How do I pair the beatssolo3wireless with a samsung tv?
By pressing and holding the power button, you can initiate the pairing procedure for your Beats Solo3. This step should be done when the headphones are off, and to confirm that the Solo3 are in pairing mode the battery indicator lights should start blinking. Then just look for the Beats headset with your TV's Bluetooth manager in the settings. The Solo3's pairing procedure can be somewhat tedious, but if the lights are blinking, then they are in pairing mode and should be able to connect to any Bluetooth transmitter/device.
What headphones would you recommend for use with Xbox One S and a TCL 55p607? I cannot afford an Atmos or DTS X soundbar or home theater system, so headphones are what I am looking at. They would only be used for movies (disc and streaming) and games. I do not use a microphone so it does not have to be a gaming headset, but I would like it to work with Xbox One S. I also would like them to function well with the Windows Sonic and Dolby Atmos apps. Do the 7.1 rated ones work any better than stereo or do the apps make them the same? Thank you.
Since Xbox One doesn't support bluetooth headphones, your best option is to pick from our top ranked Critical Listening headphones. If you are looking for an open headphone, then something like the DT990 would be our recommendation, and for a closed headphone something like the QC25, M50X, or DT770. We can't comment on how they would perform with Sonic or Dolby Atmos since we don't test them under those conditions at the moment.
Great work guys! If exclusively wired to a tv, do you believe latency would still be an issue? I wouldn't use the wireless option due to latency. Should I turn off noise cancellations for movies and games?
Using your QuietComfort 35
wired with your TV will have practically no latency. Also enabling noise cancellation doesn't add any noticeable delay (below 5ms).
Do you have any plans to test the quality of the virtual surround sound offered in gaming headsets like this?
Not at the moment, and we suspect it won't be easy. But if there's enough interest in it, we will look into it.
Differentiating truly wireless headphones - e.g. Apple's Airpods - from wrap-around Bluetooth will be important going forward.
Thanks for your suggestion. We agree with you and will make appropriate changes once we have a good plan.
About one year after purchasing a set of AudioTechnica M50x Headphones, I noticed that the skin on the padding was coming off. Is this something you noticed as well, or is this just on my end?
At the moment we don't see any significant cosmetic issues on our M series headphones, but we most likely haven't used them as much as you either. Overall, your experience doesn't sound out of ordinary too us.
I am looking for a new pair of over-ear headphones with emphasis on sound quality. I don’t think I am on the level of an audiophile but I still look for the best quality sound from my headphones. After some research I sorta set my goal as the OPPO PM-3
as it seems to offer the good sound quality, comfort, and the well-rounded usage I desire. I mainly listen from my mobile device or my computer and have not decided to purchase an amp yet. When I purchase a good pair of headphones I will probably make the change from mp3 files to FLAC files but again, I’m looking for something I can use on the go or if I’m in a quiet setting such as my own room. My music taste varies a lot so I want something well rounded. I am probably looking for something closed back as I am definitely not going be using these cans in just a quiet setting. Do you have any recommendations around the price range of the oppo pm3's?
Any help would be much appreciated!
The PM3s are definitely a good choice, but you could also consider the DT770, or even the M50x. For the price of the PM3 you can even go for something wireless and noise cancelling like the QC35. All of these are very good sounding headphones.
Do you have plans to measure cable-induced noise on in-ear headphones? This phenomenon is often called "microphonics" in audiophile circles (though I suspect the term is being misused). I'm referring to the audible rumbling and thumping noises that occur when the headphone cable is being moved. It seems to me that it has something to do with the stiffness of the cable. It's particularly egregious on my pair of Etymotic ER4PTs, for example.
Not at the moment. We have noticed that some headphones do worse than others at being microphonic, but haven't thought about coming up with a test for it yet. If there's enough requests for it we will add it to our test bench.
Hello! I am currently heavily debating between the PXC550s and the QC35s, but I'm still torn even after reading both of their reviews. One question I have not been able to find an answer to is what is the quality of the microphones? I briefly tested the QC35 in Best Buy as of September 2017, and I noticed a lot of background noise/hissing. I have not been able to find a pair of PXC550s on display to test them out. I'm curious about this because I will be using these in an office like environment for phone calls. Were any official tests conducted on these mics? If not, could you perhaps comment on their call quality? Also, was the audio pass through better on the PXC550s than the Sony MDR1000X? Thank you in advance!
We have just published our microphone test results, and you can check the results for yourself here
. Based on our tests results the PXC 550 is slightly, but noticeably, better than the QC35. The audio pass through is not very different between the 550 and 1000X. We have also made recordings of the microphones' performance, which are planning to make available on the website as part of a playback feature.
Hi, My question is can these headphones also be used for gaming? Thanks.
They will sound good for gaming, but they don't have a microphone, don't have good noise isolation, and leak a lot. So if these are important for your gaming, consider a closed-back headphone that has a microphone.
From, other reviews, I believe one of the criticisms of this particular headphone model (HD 700
) is the presence of a sharp treble peak.
Does your rating system address peaks and dips in a different way from, say, smoother deviations from ideal response?
We generate the scores by calculating weighted standard deviation, and the weighting filter we use resembles the equal loudness curve. Therefore, our current algorithm treats peaks and dips the same way, and does not penalize narrower peaks over wider peaks. That's why the HD 700 is not being penalized enough for it's 6.5KHz peak.
Improving our scoring algorithm is quite high on our to-do list at the moment.
You mentioned in the video that you don't measure beyond 2k frequency on human subjects. You do show one measurement using your ears your ears beyond 2k for the HD 600
vs HD 800 comparison ion the same video.
The FR consistency graphs in the reviews show the full FR range for 5 tests - Are they just based on HMS positions, or across HMS and human listeners?
The graphs on the website include human measurements up to 450Hz, and above that we show only HMS measurements. The full-range human measurements shown at the end of the video was just to show the difference between humans and the HMS.
The HD700 looks good... That is, until you look at them on the time domain, then you realize that it has real nasty ringing in the treble in the same spot it has a peak. Look at innerfidelity. The ringing is so bad that it never stops in between the transients on the 300hz square wave. I heard the treble as a mess of random high frequency noise.
Care to do a cumulative spectral decay or impulse response measurement on them? If the program used here on rtings doesn't do that, you could download Arta and screw with that.
There's a lot of information in the time domain that isn't represented on this website, which is a real shame, as I'd go so far as to say that clean and uniform decay across the audible spectrum is just as important to the end experience as a good frequency response or low distortion.
It's why the HD800 resolves detail like no other. Outside of a short lived resonance at 6khz, the HD800 is clean down to a -64dB noise floor. The HD800S addresses that 6khz resonance by placing a helmholtz resonator in the center of the driver to kill a standing wave that gets reflected to that spot, but also unfortunately has some extra bass distortion. Which is odd, as DIY resonators placed into the HD800 don't exhibit the increased THD of the 800S.
Either way, information in the time domain is crucial to evaluating headphone performance, and should be included in any set of headphone measurements.
Thanks for your email. We agree with you for the most part and we have considered including CSD and other time domain dependent tests (such as group delay) in our reviews. However, adding new tests and metrics properly takes time, so we would like to add CSD and other metrics when we can dedicate the proper amount of time and resources to it.
Have you guys considered changing you color coding system for your headphone reviews. Objectively if you look that the whole list of youre reviews it's give the impression everything that you have tested thus far is either bad or mediocre. Since most of the ratings end up in the 6-8 range pretty much everything is is yellow or worse with spots of green. With the current system you have the only headphones based on the numbers that will look good are Portable usage headphones. Everything else will probably be plastered with low rating for being bad at something they weren't designed for. Ultimately im saying the rating system needs to be revisited because it favors the wireless all rounders the most.
Thanks for your feedback. We do agree with you that our scoring can be improved to better match the subjective impression of them. We are planning on updating them in the near future and will consult your comments when doing so. However, not all of our ratings favor wireless headphones, for example, the Critical Listening usage rating, doesn't not include wireless.
are these compatible with a tracphone?
Depends on the model. If it supports a 3.5mm headphone jack, then yes.
If the Box Sennheiser RS-195 is purchased from Amazon.com will the SennHeiser 2-year warranty guarantee apply ?
We contacted Amazon.com and the item "Sold by avSoundz and Fulfilled by Amazon.com" is covred by the 2-year warranty. If you are planning on purchasing a different one, we would suggest that you chat with an Amazon representative to confirm.
I have been very pleased with the Bluedio headphones and would recommend them to others based their audio performance and comfort. They sound great compared to others at their price range. I am very happy with them.
Thanks for your feedback. Sound quality can definitely be a subjective thing, however, based on our test methodology which favors neutral sounding headphones the U-Plus doesn't do too well.
Hi, I purchased these headphones primarily because of the aptx Low latency feature because i want to use these a lot with watching video content. however i purchased an aptx low latency bluetooth transmitter, paired it with this device, and I'm getting the same performance as if i was directly connected to bluetooth on my iPhone. Platronics customer service just told me to make sure i was on the latest firmware which i was, and if it still didn't work to send the unit back. Before i do i was just wondering if you had any troubleshooting tips. And also confirm you've tested and have worked with these headphones with an aptx low latency device at 35ms like your specs describe. Thanks!
If you go the Latency section of the SBC vs AptX: Which Bluetooth Codec is the best?
article, there are two videos showing the actual latency test results for the Plantronics Backbeat Pro
2. We did this test with the Mee Audio Bluetooth transmitter, and an aptX-LL connection was established between both Bluetooth devices. The issue may lie with your transmitter and not the headphones as we have also have a Tao Tronics transmitter that is supposed to support aptX and aptX-LL but has never established an aptX-LL wireless connection with an aptX-LL ready headphone. If you can test with another transmitter, then you should be able to confirm if the issue is with your Backbeat Pro 2.
It's been almost 1 year ! You didn't review with Hi Res. It out a serious question on your review for reliability and trustworthiness. Folks pay high cost for high end technology. You even don't care about such measurements. Neither you cared about WH-1000XM2. You only care about the what's in current trends!! Kindly update your review very precisely with all factors for technology!
At the moment we are not able to connect our PC to the MDR1000X using one of their higher quality codecs, since our bluetooth dongle doesn't support it. Please let us know if you are aware of any PC bluetooth devices that support LDAC (and other codecs such as aptX HD), so we could measure the MDR-1000X
with other codecs as well.
You should put in disclaimers for if they are comfortable for glass wearers since I have the k702s and they hurt the sides of my head.
Thanks for your feedback. We will consult our colleagues in the office who wear glasses and will update the review if needed. However, we have noticed that not all glasses have the same effect on comfort or even sound, so the K702
may not be uncomfortable for everyone with glasses.
You guys are the best! Great work! I'm looking to buy some Bluetooth wireless headphones to watch movies and game through my pc, I'll hopefully be getting the MEE wireless transmitter you recommend with aptx LL. Are these the best headphones I can get that are Bluetooth for gaming and movies? Thanks!
Yes, the Plantronics Backbeat Pro
2 are the best Bluetooth headphones for gaming and watching movies that we've tested so far, as long as the transmitter you end up getting supports aptX-LL. We chose the MEE audio transmitter because it can also connect to two headphones simultaneously, which may be a feature you won't need.
Running and jumping?? and you BOTH took credit for this review? Whoa.
are not stable and would be a poor choice for sports use. Exercising with the headphones are part of our testing procedure but the text has been updated with a more direct explanation.
Your site is fantastic. I've really appreciated the information. I noticed in the "Best by Feature" section there is a note that the "Microphone" recommendations are coming soon. I use earbuds at work a lot and it's helpful to have a good microphone for client calls. Will you be releasing these recommendations soon?
Yes, in a couple of weeks.
I find the frequency response portion of this review to be a bit… eyebrow-raising. Specifically, I'm curious as to what methodology you use to determine what the level of the "target response" should be set to (I couldn't find anything about that in your test docs). In your review, it seems the target response level (i.e. the 90dB dotted line) was "pulled down" way too much by the trough in the midrange (and perhaps the treble), leading to some surprising scores for "Bass", "Mid" and "Treble". If the target response was set just a few dB higher, I suspect it would have made a large difference: it would have led to a near perfect score for Bass, a poor score for Mid (because of the trough), and a good score for Treble. That would have made more sense with regard to the overall shape of the frequency response.
This is also reflected by the text under the frequency response, which describes a "good mid-range", a statement that makes very little sense when you look at that frequency response and see the massive valley right in the middle of that region! (Also keep in mind that the human ear is way more sensitive to low-Q resonances like the one in the midrange than high-Q resonances like the ones in the treble region - see Floyd, Toole E., "The Modification of Timbre by Resonances: Perception and Measurement", JAES 36, 1988.) It seems pretty clear to me that this product has an excellent bass response, a somewhat passable treble response, and a very bad midrange response. But that's not what the review says at all, and I think your choice of target response level might have something to do with it.
At the moment we normalize our headphone frequency responses full range (20Hz-20KHz), post compensation. So we flatten the response first, and then adjust the level so that the average reads 90dB SPL. This makes sure that the compensated graphs average to 90dB full range, instead of only at 500Hz (which is the way Tyll does it). This way the headphones tend to get the highest possible score against our target, since our target is at 90dB. Doing it at a single frequency like 500Hz or 1KHz doesn't really work for us, since not all headphones have the same response at those frequencies.
However, as you pointed out there are corner cases which could cause problems for our normalizing algorithm. Perhaps one way to improve it would be to apply the weighting curve we use for standard deviation to our normalizing algorithm as well. Kind of like applying a A or C filter to an SPL meter.
I suspect that the way you compute scores from the various parts of the frequency response is a bit overly simplistic with regard to the way the human ear perceives variations in frequency response.
Specifically, it is well-known that when it comes to resonances (i.e. frequency response peaks), low-Q (broad) variations are way more audible than high-Q (narrow) variations. Probably the most well-known study on the subject is the one by Toole, Floyd E., "The Modification of Timbre by Resonances: Perception and Measurement", JAES 36, 1988.
What this means in practice is that, for example, a headphone that is wiggling around in the treble (as most headphones do) is way less objectionable than a headphone that has a somewhat smooth, but tilted, response. At the most extreme, an overall bass/treble balance tilt is the most audible of them all (the study above showed that it's possible to notice a wide spectral tilt of only 0.1 dB!), and it's going to be way more audible than narrow peaks and valleys in the response.
The problem with your calculated score is that it is based on a standard deviation calculation, which is blind to these subtleties. Indeed, when calculating standard deviation, a series like [-10, 10, -5, 5] (to take a small example) will yield exactly the same value as [-10, -5, 5, 10], but if these were numbers from a frequency response a human subject would not agree that these sound as good as each other: the first series is simply hovering around a central value, while the second series is showing a clear overall tilt. They will be perceived very differently, and the deviations in the second series will be significantly more audible than in the first series.
Another phenomenon that your scoring function does not take into account is the well-known fact that peaks in the frequency response are more audible than valleys or dips. See Bücklein, Roland, "The Audibility of Frequency Response Irregularities", JAES 29, 1981.
In light of these findings I hope you'll agree that your scoring function has room for improvement, and perhaps it would be possible to come up with more appropriate math that would better account for the psychoacoustic properties of the human ear.
That's correct. At the moment our scoring is a weighted standard deviation, with the weight curve being quite similar to the equal loudness curve (less weight to low-bass/high-treble). However, adding more perceptual components to our scoring algorithm, like the ones you pointed out, is something we have been meaning to do for a while. Chances are that'll be one of the high priority tasks on the list after we publish our microphone test results.
First of all, let me say that I mostly agree with the way your highly rigorous headphones tests are conducted. You are, by a large margin, the most scientific, data-driven headphone review website that the Web has to offer, and that is absolutely amazing. Keep up the good work!
That being said, I'm the nitpicky type… and while I fully agree with most of your metrics, especially your target frequency response curve which is based on the latest research (Sean Olive be praised), some of them leave me a bit… sceptical, to say the least.
Specifically, the section that worries me most is the "Soundstage" section. This statement in particular:
"This means, unlike closed headphones that have limited acoustic interaction with the objects and walls in your environment. Open headphones encourage these subtle effects, which enhance sound quality and make it a more immersive listening experience. [closed-back models] don't excite the acoustics of your surroundings like open-back headphones, which is significant when critically listening."
Do you have a citation for this? Because that's the first time I've heard such claims, and I am quite skeptical of them. Quick back-of-the-envelope calculations suggest that the leakage from even a very open pair of headphones is far, *far* too weak to produce audible reflections off the surrounding environment. (I arrived at a -40 dB figure for a reflection off a wall 1 meter away in the most optimistic scenario, a level that has been proved to be inaudible in a number of studies - the threshold is more like -20 dB. See Toole, Floyd E. "Sound reproduction: Loudspeakers and Rooms", chapter 6 "Reflections, Images and the Precedence Effect" for a good summary of the research on the perception of acoustic reflections.)
In fact, there is evidence to suggest that the perceived differences between open-back and closed-back headphones can be explained purely by differences in frequency response (e.g. open-back headphones typically have less bass). For example, one of Olive's AES papers, "A Virtual Headphone Listening Test Methodology" (51st AES conference, 2013) shows that it is possible to make open headphones sound like closed headphones (and vice-versa) simply by equalizing them to the frequency response of a target headphone. The results are quite convincing.
For these reasons, I hope you can understand that I'm not convinced that your "Soundstage" section conveys useful information. I don't believe the "Openness" and "Acoustic space excitation" metrics are perceptually meaningful; I'm having trouble understanding PRTF (isn't that redundant with your target curve?); and there doesn't seem to be much point in measuring crosstalk since all the headphones that you've measured show very low values for that metric, as one would expect.
So, if you could provide your references for your claim that the perceived differences between closed-back and open-back headphones are caused by acoustic interactions of the headphones with the listener's surroundings, I would be curious to peruse them. Thanks!
Thanks for your question. In general, we do agree that some of our tests are more theoretical than empirical. This is something we want to improve, however, this is also a relatively new field, and sometimes we had to come up with our own tests because we couldn't find something similar in the literature. So I'm going to briefly describe the theory behind our soundstage section, and we would be interested in hearing your thoughts on them.
The "gold standard" for our headphone sound measurements (i.e. a device that would get 10/10 in our Sound section) is "the perfect stereo system in the perfect room", whatever perfect means! So our headphones are measured against a theoretical perfect loudspeaker setup. For localization tests, our approach is to divide them into two: Soundstage and Imaging. Note that these are our definitions of soundstage and imaging, and others may have different definitions.
Imaging qualities are inherent to the audio content, the headphones have to 'reproduce' them rather than 'create' them. They determine how accurately the objects are positioned in the stereo image. In other words, the localization cues that are already in the music (ITDs and IIDs).
Soundstage qualities are not inherent to the audio content, the headphones have to 'create' them rather than 'reproduce' them. They determine whether the sound is perceived to be coming from inside or in front of the head, how open and spacious the soundstage is, how much the headphones acoustically interact with the environment, and how strong the phantom center is.
So basically the combination of HRTF, room/reverb effects and crosstalk is what we put under Soundstage. In other words: the difference between a pair of loudspeakers in a room and a pair of headphones. To test for these differences, we have developed 4 tests: PRTF, Openness, Acoustic Space Excitation, and Correlated Crosstalk.
The metric that we call PRTF (pinna-related transfer function), is derived by measuring the headphones on the dummy head, once with the pinna attached and once with the pinna removed (we have an extra ear with the pinna cut off specifically for this test). The difference between the two frequency response measurements is the PRTF. This result will be scored against our reference PRTF which was derived by measuring a loudspeaker with and without the pinna, in a simulated anechoic environment, more than a meter away, at 30 degrees in front. This shows how much of the FR at the DRP (eardrum) was created using the pinna. As you can imagine, in-ears do not interact with the pinna at all and therefore their two measurements are identical. On the other hand, the HD 800 S and the Edition X show the most interaction.
We do agree with you that this is not the best way of measuring the HRTF effects of a pair of headphones, since all the information we need is already in the impulse response (FR+Phase) and there's no real need for measuring the headphones without the pinna. But for that we would need to be able to isolate the HRTF information in the impulse response, and we don't know how easy that is to do. But this is something that has been on our radar for some time, since we know in-ears that simulate HRTF using DSP are just around the corner and we can't measure that with our current method.
Openness, which is the inverse of our isolation test, is there account for the subjective feeling of the music being part of the environment. We don't have research to backup our hypothesis, except for the listening tests that we have performed internally, and for us there was definitely a difference in the perceived openness and spaciousness of soundstage.
We also agree with you that the effects of Acoustic Space Excitation (i.e. the inverse of our leakage test) are very minimal, and in most cases barely perceptible. But we included it in the spirit of being thorough. That's why it's only 10% of the soundstage score. However, in our internal listening tests we have been able to detect it with very loud and very open headphones (e.g. Listen to loud percussive music on a pair of Grados and then walk in and out of a bathroom and see if you notice the bathroom reverb being mixed with the music).
Same for crosstalk. It's been included in the spirit of being thorough and true to our "gold standard". But we haven't measured a single headphone so far that produces any useful crosstalk.
Looking forward to your thoughts.
Hey, any chance you could do a comparison between the Apple AirPods
and the jaybird run earbuds? Please include microphone quality in the review. Also I'm sure it's on the horizon, but any word from bose of a similar product (completely wireless Bluetooth earbuds)?
We are not aware of a truly wireless headphone from Bose yet, but we are planning on reviewing the Run soon after they become available. The review will include a section for microphones as well.
When using a wireless set that has the ability to be wired also, does that wireless unit then lose all the latency usually associated with its bluetooth connection. Example would be Say the momentum 2(wireless) being used in wired mode vs its completely tethered brethren the momentum 2(wired). Have you tested the wireless headsets(any) in wired mode to see if there are any gains in performance if any?
Yes, the latency of a wireless headphone will be the same as a wired model if you use them a with an audio cable. In all the cases that we have tested so far, once you plug in an audio cable, the wireless headphones automatically turn off their Bluetooth receiver and behave like normal, wired headsets. There are other benefits to using a wired connection over a wireless one, like slight improvements in sound quality, as mentioned in the wired vs wireless
article. However, we have yet to test the full extent of wireless codecs, and cannot yet draw a conclusion as to how much better a wired headphone will sound compared to its wireless counter part.
I am going to upgrade headphone in my studio.
Do you think DT1770 pro will be a great experience for imaging or just keeping my M50x ?
Thanks for your question. Unfortunately, since we haven't measured DT1770 yet, we can't comment on how they would compare to the M50x.
Thank you for noticing the missing cable length. This issue is fixed and the review has been updated.
Any chance you'll ever review the Stax SR-009? I know it's $$$...just curious
Chances of us reviewing anything above $1500 at the moment is very very slim.
I'm a trap producer looking for a headphone to mix and master on. What do you recommend?
We would recommend a closed-back headphones like the Audio Technica ATH-M50x
. But if you want an open-back headphones, then the Beyerdyanmic DT 990 PRO
would be our recommendation.
Soundstage is missing prtf & crosstalk..
Thanks for pointing out the error. Fixed!
Hi, I'm a bit confused to see the HD600 and M50x both having the same critical listening score, that doesn't make any sense! is there an error or...
Thanks for your question. The M50x has a better bass and in general a better frequency response than the HD600. But the HD600 is open-back, which means it has a better soundstage. In our current scoring configuration, these difference cancel each other out.
Curious why you picked these to review over the Samson SR850? Samson is easier to drive, more comfortable, better bass performance.
Thanks for your suggestion. We picked the Superlux because it was high on our suggestion list, and we weren't aware of the SR850 until now. You can submit and vote for your suggestions here
Why does the mixed usage score, not give more ( or equal ) weight to 'home theater'?
We've decided that the Home Theater use case is more niche than the other score sets. Therefore, most headphones shouldn't be heavily penalized, for mixed usage, due to a below-average score for home theater use.
Is it just me, or do your score components, equal 99%? ( I know I got a D- in beginning algebra, but c'mon..lol )
This is a rounding error in our algorithm. We are aware of the issue and working on a fix.
'A sufficiently decent soundstage'?! Honestly?..between that and a poor imaging, a decent critical listening score is the most it qualifies for..
The conclusion text for this review has been updated to better reflect their current score.
'Not ideal for critical listening'?! That's being kind, and a bit of an understatement.. (?)(Lol ))
The Critical listening score set is not only based on sound, but we do agree that the Denon Globe Cruiser have a sub-par frequency response, soundstage, and Imaging. In other words, they sound too dark and closed for critical listening but they are very comfortable.
'Mediocre for critical listening', is being generous..
The Creative Sound Blaster EVO ZxR
have a poorly balanced audio reproduction which would not be suitable for more critical listeners. However, they do have the powerful bass range and an efficient parametric equalizer accessible through the app, which should be good enough for casual listening and fans of bass.
For those who mistake excess bass, for good sound...lol
We agree, the Bluedio U Plus
have a bit too much bass, which makes them sub-par headphones for critical listening. It's also why they have a below-average score for our Bass test.
This review needs updating..'average for critical listening', is a bit generous..
The SMS Audio STREET by 50 have not been updated with the new test bench. The text and score will not be directly comparable with our more recent reviews.
I have the samsung Level U pro which I know support the APTx codec but I'm not sure what devices support the tech. Do I need a specific Bluetooth version for the Aptx to work? or is it an independent tech which I need to look for in all my devices before purchasing?
For the aptX codec to work, both the Bluetooth source and the receiver need to support aptX. This means that codecs are independent of the Bluetooth version, so unless your source supports aptX, your Samsung Level U Pro
will default to the SBC connection. Learn more about Bluetooth
There are many Bluetooth transmitters available online that supports aptX and aptX Low Latency. We use the Mee audio Bluetooth transmitter, but there are other options available that may be more specific to your needs on Amazon.
'Above average for critical listening'?!...Really?!...
This is an older review so the text is slightly out-of-date. However, we are currently updating the text for many of our past reviews, so the conclusion for this headphone will be updated too.
'Decently well balanced sound' or 'poorly balanced sound quality' - well, which is it?! I own these, and feel the sound quality is fantastic for the price, and just plain good, overall. Thank you for your reviews though..
Thanks for pointing out the error. Some of the texts currently on the website are out-dated, due to updates to our test bench and scoring. We have started updating them, and most of them should be up-to-date by the end of the week.
Regarding the sound quality of the Koss UR20, they do have a good Bass, but they sound a little bit mid-rangy and their Treble is slightly inconsistent. So I would say their overall sound quality is about average.
Hi,I'm wondering how the sony mdr-1000x using the wire instead of the wireless feature compares to the sennheiser hd 650? I've used the side by side tool, but it was reviewed using the wireless feature. You guys said that without the wireless being used, the treble was pretty flat. And if so would be very similar the 650's. I saw the graph for the 1000x wired for THD, but how much did it improve? And does the imaging improve also when using them wired? The raw frequency response looked excellent using it wired. Also looking at the bass which may be the most noticeable, which pair of headphones do you think would be preferable considering everything? Thanks for your time.
The "Portability" for this one may be misgraded. It says 9.1, but the text seems to indicate that they are not very portable. Mistake?
Thank you for noticing the error in the Turtle Beach review. The portability score has been updated.
Are these safe to be used on plane trips?
That will depend on which airline you use. Bluetooth headphones in most cases should be fine as long as your Bluetooth source is not a phone or a device with a Sim card/cellular connection that has to be put into airplane mode. However, we would strongly suggest checking the airline's restrictions and regulations for your flight.
Hey, with that dummy head, I'd expect some impulse response graphs. square waves please!
Thanks for suggestions. Adding square waves would be a bit redundant since we already score the Bass Range separately. But adding impulse response is something that we have on our road-map, and will add it at some point in the future.
I'm looking for over-ear bluetooth headphones that will only be used for TV movie watching. These seem to fit the bill but what concerns me is the latency. 173ms seems way too much for it to be unnoticeable. 34ms for the aptX LL sounds great but how do I figure out if my TV (Sony 65X900E
) is compatible with the codec? There is an "a/v sync" option in TV menus that apparently adjusts timings when bluetooth devices are connected but I'm not sure if it's an actual lag compensation and whether it does anything. Am I better off forgetting about using bluetooth for movies? I'd really like to go wireless because plugging the cable in the back of the TV every time is a major hassle.
The Sony 65X900E does not support aptX Low Latency. We tested our Plantronics Backbeat Pro
2 on the X900E
and noticed a significant improvement in latency when the A/V sync setting was enabled. There is still somewhat noticeable delay, but it won't completely ruin your movie experience. However, for home theater use, RF headphones are a bit more suitable than Bluetooth ones. Check out our best Home theater recommendations here
I believe a lot of users would appreciate if you could test 250 Ohm or 600 Ohm version of these headphones. Based on multiple reviews, it should perform better than 32 Ohm version. And I am sure that most of us would be very interested to see reviews of the new generation Beyerdynamic headphones that use Tesla coils.
Thanks for your suggestions. We will consider testing a higher impedance version of the 880, but it'll be a lower priority for us, since we have other headphones in line to be reviewed and published.
Regarding the SHP9500S they do have differences than the 9500 since the 9500S is a striped down version of the 9500 with cheaper rubber instead of gold on the jack port and not including the bag and adapter as well as a shorter wire. The biggest thing to note though is a lot of people have said the 9500 has more bass but less treble while the 9500S has more treble and less bass. Being the striped down version of the 9500 there is a difference in price with it being $55 on newegg for the 9500S and $75 on amazon for the 9500 (although the 9500 on amazon I seen reviews say its really the 9500S that you get since the 9500 was discontinued).
Thanks for your information. We were aware of the cosmetic and build differences between the two models, but not the reported sound differences. We will consider reviewing the 9500S, but it'll be lower on our priority list.
However, since Philips has mentioned on their forums that the difference is purely in build and cosmetics, it is possible that the reported difference would be due to manufacturing tolerances and/or listener's positioning preferences.
supposedly get better with a software update on iOS through 10.3.3. One of the features that were presented in this update was less latency, are you guys able to do a retest. Possibly to get more accurate results with the new update?
We retested the AirPods
running Firmware version 3.7.2 and did not notice any improvements in latency. However, we test the latency of all our Bluetooth headphones with the same three Bluetooth dongles and not with an iPhone or iOS device. There may be an improved encoding algorithm with iOS 10.3.3 or a software based compensation, that delays the video to be more in sync with audio, but we cannot reliably measure that with our current test bench. Learn more about our Latency test here
Could I use the Sennheiser PXC 550 or momentum for bluetooth TV use?
Thank you !
Yes, you can use the PXC 550 Wireless
or the Momentum 2.0 Wireless
with a Bluetooth-enabled TV. The Momentum especially have a bit less Base latency than the PXC 550 but they're not as comfortable or as feature-packed. Unfortunately, both have relatively high latency so they won't be the ideal headphones for watching videos. Check out our Wireless
article and Home Theater
recommendations for more options.
I want to know the effect of Volume-optimized EQ of this earphone
We haven't noticed any notable change in the frequency response of these headphones, by changing the level of the test signal between 100dB SPL and 70dB SPL.
Since you're pretty much recommending this model (Jaybird Freedom
F5), you could do one more helpful thing for everyone: Adjust the built-in parametric EQ using MySound so that it matches your target response as close as possible, and then make that sound profile available to the public, which can be done in the MySound app itself, I think.
I pretty much ignore the "Soundstage" portion of the reviews because I've never heard anything like realistic imaging from any headphone without resorting to a Smyth Realiser or something similar. And I imagine that it would really be distracting without a head tracker. For me, it's best for "soundstage" not to call undue attention to itself. But what could really be done is to optimize the frequency response, which does affect the sound quality in a big way--perhaps the biggest single factor.
That said, I'm going to assume that the measurements for this model were made using the pictured Comply foam tips. Typically, insertion depth-dependent resonances are damped out by the foam and you don't see the kind of spikes that you see in the frequency response like in your measurements for the Jaybird X3
. (I'm going to guess that those were made with the silicone tips.)
So if you published MySound settings for the Comply foam, the results would likely be more repeatable than for silicone. And it would probably help more folks than if you did the same with full-size headphones, which are affected by individual listeners' pinnae and the diffraction effects that come with them. It would make great starting point for further adjustments than from the stock sound.
BTW, I'd love to see you guys measure the JBL Everest Elite 750NC. That too, has a built-in EQ, plus it has TruNote Auto Sound Calibration that supposedly makes the response close to the Harman Target on each individual wearer.
Thanks for your suggestion. We have thought about publishing correction curves for our measurements, but at the moment is not our highest priority task.
It's true that headphones, in general, don't have a very good Soundstage at the moment. But still, some perform better than others in the Soundstage department. Also, depending on the use, Soundstage with head-tracking could actually be more distracting than a Soundstage with no head-tracking.
Both the X3 and Freedom were measured using silicon tips. We are aware of some variations in the Treble Range across humans, both with over-ears and in-ears, and we are thinking of ways to account for that.
We have already measured the Elite 700. Do you know what the different between the 700 and 750 is? We couldn't find any useful information on the JBL's website.
Purchasing strictly for Blue tooth use with TV. For this purpose, do you think that Bose QC 35 is the best choice? Better selections ? Thank you!
The QuietComfort 35
have a pretty high base latency so they won't be the ideal headphones to use with your TV. Our best Bluetooth recommendation for home theater use are the Plantronics BackBeat Pro 2
. However, to get their best latency performance you may have to purchase a Bluetooth dongle/transmitter that supports aptX Low Latency.
If you strictly need a home theater headphone, then the Sennheiser RS 165
are your best option. They are radio frequency headphones, limited by an RF transmitter stand but have an excellent base latency that's ideal for watching video content. Check out our best home theater recommendations here
I see that you have tested the 250 ohm version of the headphones for this review. Did you run these 250 ohm headphones through a headphone amp when conducting the review (and is that where these Sound quality stats come from) and if so which amp? Wondering if an amp is necessary or if I can reach these sound quality scores you've posted using a smartphone/CD player.
We use an RME UFX as our DAC an a Schiit Ragnarok as our amp, but you don't need very expensive equipment for the DT-990. We also have an Asgard 2 amp and our headphones measure basically the same on both, but the Asgard 2 doesn't get as loud.
It shouldn't be much different with a smartphone either, but again, if you listen to older tracks or podcasts that generally are not too loud by themselves, they may only get moderately loud.
If u can use dac/amp to drive westone w40 i think it will get better score, i really dont understand how would bose QC30 will have better sound quality than w40. I suggest you to listen to them for 3 days and can start to compare them.I own sony mdr1000x, akg 712, bose qc30, senh 600,sph9500s, akg n20, senh momentem in earwestone w40, w60, ve6 and some diy in-ear earphone. I really dont think bose qc 30 would have a 6.9 critical listening score since w40 has lower.
Thanks for review my question.
We use an RME UFX as our DAC an a Schiit Ragnarok as our amp, so there's not much we can improve there. Regarding the target response, it could definitely be a matter of taste, but based on the target response we have settled on (which is loosely based on the Harman Target Response), the W40 doesn't perform too well. Also, our results are supported by this paper that concluded there was no correlation between the price of headphones and their frequency response.
You can find out about our target curve in a video here.
It says no for the passive playback but in the description you mention that the audio quality doesn't deteriorate much after the battery runs out. Can you confirm if it actually has passive playback and does the mic work without the battery?
Thank you for catching the error on the Skullcandy Crusher
review. Yes, they can be used completely passively without any batteries. The text is accurate and we have now updated their status for passive playback. However, when used passively you don't get any bass enhancements, which sounds about the same as when the bass slider is set to 0.
Is the latency value of the SBC codec? I want to know the latency at the AAC codec on iOS devices. Is there a change in the frequency characteristics of this earphone depending on the size of the volume?
Yes, the current base latency value is that of the SBC codec. We have yet to find a reliable Bluetooth dongle that supports AAC and also works with our test bench. Therefore we cannot yet comment if the sound quality of these headphones will be significantly better.
How does the auto off timer work? Do the headphones go off after the allotted time, no matter what you are listening to? Or does the timer refer to times when the headset is not actually playing anything but is still on and thus goes shuts down in idle to save battery?
Yes, the auto of timer only switches off the headphones when they are idle (i.e not playing any audio).
This is being replaced with the SHP9500S model. Have you had any experience with it?
Some have said its just a cheaper version and the quality has really gone down
We heard about the S model just recently, and don't have any first hand experience with it. However, based on what we found on Philip's official forum it seems that the two models are meant for different regions in the world, and the difference between the two is mostly cosmetic and not in sound.
What would you recommend for home tv/movies and games that is wireless as an alternative??
The Plantronics Backbeat Pro
2 would be the best suited for gaming and watching movies especially if you have a Bluetooth dongle with apt-X or apt-X (LL). You could also consider the Parrot Zik 2.0
they're a lot cheaper than the Zik 3.0
and they have a relatively fast Bluetooth connection without the additional aptX codecs.
I've used this site many times in the past for its exceptional accuracy & reliability for TVs. I started looking at your headphone reviews. I'm honestly a bit disappointed, I did not expect a site so renown for knowledge to put a "target response curve for a headphone as a completely flat line.
Sean Olive has done a lot of reasearch in this area & has published a "harman curve" as many call it to show an approximation of what a headphone should sound like. I would urge you to either use the Harman curve or none at all & explain its generally easier to compare a headphones FR to ones you know as the dummy head itself can have a great effect on the measured response.
Thanks for your email. The graphs on our website are compensated, based on a compensation curve quite similar to Harman's. We have flatten our target curve so it would be easier to read. You can find out about our target curve in a video here
Given the type of headphone you are reviewing, I think it would be nice to also have amplifier recommendations, whether general, like basic specs or more specific like models.
Thanks for your suggestion. That would require us to review headphones amps, and reviewing a new product category takes a lot work. We may add them when we have the time to develop a proper test bench for headphones amps.
How does the sound quality compares to the Bose QuietComfort 35s.
They are quite similar. The main difference is that the JBL could sound a bit sharp and sibilant on certain tracks, compared to the QC35. But if you look at their frequency responses, they are within a couple of dBs of each other up to 9KHz.
Soundmagic e10 please review, excellent in ears
Thanks, noted! By the way, we have a new tool for suggesting products to be reviewed and you can submit and vote for your suggestions here
Hey I'm trying to protect my ears and would like to know the maximum volume decibels and the half volume decibels. I use them for about 2 hours in the morning and want to make sure I'm staying under about 80 decibels.
This is highly dependent on the type of program you are listening too. A heavily compressed electronic tune could go above 100dB SPL at full volume, but an audiobook may go up to only 90dB at full volume. Unfortunately there's not an easy way of finding out how loud your listening level is, unless we can use the same source that you are using.
Before testing, was the headphone updated to the lastest firmware update?
Yes, they were measured with the latest firmware available.
How does the sound quality compares to the Sennheiser Momentum Wireless?
They are more balanced than the Momentum. The Momentum has too much Bass and not enough Treble.
Beats. Why does this website recommend them when EVERYONE else doesn't? Is it just a trend to bash beats into the ground?
Because the more recent Beats (post Apple acquisition) are actually really good! That seems to be the consensus online as well.
Your noise cancellation measurement of Bose QC25 and QC35 shows non-cancelling at about 70 Hz. In other measurement on the internet (innerfidelity.com, about.com, etc.), does not have that non-cancelling at about 70 Hz. What makes the difference? The headphones are from different batch? Or measurement artifact?
The Isolation box that we measure our headphones in, has a bit of a buildup at around 60Hz but that's compensated for post-measurement. Because of the build-up, some headphones can't handle the loud levels that are produced around 60Hz and therefore their noise cancelling system clips. We are looking into improving this, but it is not a big issue in our opinion since it is the same for all headphones. Not all of our noise cancelling headphones have the bump around that range, meaning that some headphones are better at handling low-frequency noise up to 120dB SPL, and some others can't.
Alright, so i'm looking for some good, closed, portable, fullsize headphones. They would have to be under 250 and be stable enough to stay on when I run. I don't care if they're bulky or if they're ugly so long as it's comfortable. My previous headphones are the hd 598 and the ath 900x if you need to know. Thanks in advance!
Here are our suggestions: Bose SoundTrue Around-Ear II, Bose SoundLink Around-Ear II, and Plantronics BackBeat Pro 2.
Between the 3: SoundTrue is the cheapest, but wired. SoundLink sounds best, but doesn't have noise cancelling. Backbeat Pro 2 does have noise cancelling, but doesn't sound as good as the other two. The difference in sound is not huge between the 3, and all are good sounding, so it comes down to your preference and budget.
Can I use the MDR-XB950B1
wirelessly with the Playstation 4 via Bluetooth?
Weren't able to pair it. Our PS4 says that it does not support Bluetooth Audio Devices.
Hello, I am trying to seek your expert advise for a set of headphones. My goal is to find a set that is wireless so I can use them while I do yard work and block out sound while listening to music, talk radio etc from my iphone. I also work from home in my office and would like the same pair to be able to connect to my cordless Panasonic phone via included cable with the headphones to the 2.5mm headphone jack. Reason being is that I am on a lot of conference calls and that had to be a big factor in my search. So needing active noise cancellation, wireless and a cable to be able to connect to my phone for work. So far I narrowed it down to the Sennheiser PXC 550, Sony MDR-1000X
and the Bose QC 35. I would love your advise on which one and even if its a different model I have not thought of. One thing to note is that I do understand that it will be a jack of all trades headset and i dont have to have the best noice cancellation or audio. The most important is the call functions with the cord. Thank you in advance!
QC35 and MDR1000X have superior noise cancelling compared to the PXC550. With MDR1000X you have the option of turning the ANC off, but with QC35 the ANC is always on. On the other hand, the QC35 has the best sound quality out of the three, but it requires a 1/16th TRS jack instead of a 1/8th (2.5mm).
If you don't care about being able to turn off the ANC, and can find a 1/16th jack adapter, then we'd recommend the QC35. Otherwise, the MDR1000X would be a better fit for you than the PXC550 because of their better ANC.
Did these ratings change recently? They seem quite different, and some of the text doesn't seem to correspond to the scores. For example, 8.1 for imaging meaning average imaging?
Yes. The review has been updated with our latest test bench. The text will be updated after all the headphones have been updated.
I'd like to get an inexpensive pair of headphones for listening to podcasts while mowing the lawn. I want ANC to eliminate/reduce mower noise so I can listen at a reasonable volume. It looks like there aren't really any reasonably priced (under $1000) options that do a good job of noise cancellation though. Would the Plantronics Backbeat Pro
be any good? What about the CB3 Hush?
Both in our measurements and subjective tests, the Sony MDR-1000X
performs best in Noise Cancelling. However, we don't have a reference for the noise profile and loudness of a lawn mower, so it may or may not be adequate. Our other recommendations would the Bose QuietComfort 35
and QuietControl 30
Can you please elaborate on your methodology when measuring with human subjects? Do you still also measure on the dummy head? I don't understand it.
We are working on a video to better explain our issues and workarounds for headphones measurements. In short, we measure over/on-ear headphones on 5 human subjects, 5 times each. We also measure the headphones 5 times on the dummy head. We then merge the results of the two sets of measurements (human and dummy head) in the Mid Range to get the final Frequency Response.
I'd love to see the HD 700 reviwed
We have a new tool for suggesting products to be reviewed! You can vote for the HD 700 here
Why didn't you lock 1 kHz to 90 dB? And did you change the compensation curve recently? A lot of the measurements seem to have a hump around 2 kHz while there used to be a dip (800S, M50x, HEX, SHP9500
We don't lock down the response at 1KHz, because it won't align the Frequency Response across the Target SPL properly. Currently we align the response full range (20Hz-20KHz), but we are open to suggestions for doing it differently.
We have just updated our Target Response (compensation curve), which you can see below, and we are in the process of updating our measurements and scores with the new target. That's the reason for some changes on the website.
All the headphones will be updated to the latest test bench (which includes measuring the bass of over/on-ear headphones on 5 human subjects), by the end of April.
I prefer ON-EAR Wireless headphones because they seem to fit better and are less bulky, especially when my head is on a pillow (OVER-EAR headphones seem to get pushed around). I saw the Beats Solo 3 are ON-EAR and have favorable user ratings on Amazon, but I cannot find a review of this model at Rtings.com. Do you have a review of this pair of headphones, e.g. are they comparable to anything else?
You can check our latest review of the Beats Solo3 here
My Bose SoundLink Around-Ear II
are paired with my Bluetooth ready TV. The volume suddenly gets louder at times. Don't hear a pop, but it's not a gradual increase, more like something just started working. I can't pinpoint any particular type of program and it doesn't back & forth. I just want to be sure it's not the headphones themselves, hoping it's a distance or something else problem a 76-year-old lady can't figure out. Thanks,
To confirm whether your headphones or the TV caused the sudden volume increase; We suggest connecting your headphones to another Bluetooth source, if possible, and checking if the issue persists on other devices. Also, if you have the brand and model number of your TV, we will try to reproduce the problem with our SoundLink Around-Ear II
. We will update you on the results and possible fixes for the issue, once we receive a bit more data.
I am looking for a recommendation for a great headphone to use for PC gaming. Are critical listening headphones ideal for PC gaming, or is there another type of headphone you can recommend me?
Most of our Critical Listening recommendations are open-back and don't have a microphone, so if a microphone and isolation are not a concern, then they should be a great choice for gaming. Otherwise, we would suggest a pair of wired closed-back headphones (for the lowest latency) that also come with a mic, like the Bose QuietComfort 25
Here is the raw FR plot for MDR-1000X
at 100dB SPL (Red Wired, Blue Wireless)
and here is the THD plot for MDR-1000X
at 100dB SPL (Red Wired, Blue Wireless)
Is this Qi-enabled? I have one and the USB port is broken and can't be charged with wire charger
Unfortunately, the Bohm B-66
do not support Qi wireless charging. We have yet to test a headphone that is Qi-enabled and would appreciate any suggestions
to add to our to-do list.
Did you guys notice any issues while multitasking and using bluetooth? I was using these headphones during my morning train commute, and noticed a lot of intermittent drops when using anything that required data. But if I left the iPhone locked, no issues. This makes the device unusable (for me) outside of exercise or reading a physical book. Did you guys notice the same issues? I have an iPhone 7+.
We tested the Jaybird X2
with both Android and iOS (the Nexus 6P and the iPhone 7 respectively). We played youtube videos, audio from Spotify and the native media players on both operating systems while switching between different apps. There were no connection drops as long as the devices were within range. We suggest pairing the X2
to another Bluetooth device, if possible, to isolate the issue and confirm if the connection drops happen on other devices or only with your phone.
How do these headphones compare to Bose Quietcomfort 35's?
We have experienced some measurable Sound Quality issues while using our MDR-1000X
wirelessly, but they are not terribly audible. Assuming this can be taken care of with a firmware update, the Sound Quality of the Sonys are very similar to the QC35. But the main difference between the two is the superior noise-cancelling of the MDR-1000X
and the fact that you can turn off the NC and still use the headphones wirelessly. Additionally, the QC35 would have the edge in comfort and the MDR-1000X
in build quality.
This test result only Aptx codec?
Yes, when available we use aptX for our measurements. But for the MDR-1000X
we double-checked our results without aptX as well, and still had the same issues above 10KHz.
Can you please also consider reviewing JBL Everest Elite 700 headphones? It's been well received by critics, especially since the headphones has gotten cheaper.
We have a new tool for suggesting products to be reviewed! You can submit your suggestions here
How about the over the ear version of the amazon basics headphone? Is it significantly better in terms of sound quality?
We haven't reviewed the Over-ear version of those headphones, so can't comment on it yet. But we will consider reviewing them. You can now submit your review suggestions here
Hello, I would like to know when the gaming section will be released as I see it says "Coming Soon".
Most likely in the second half of the year.
When will you test/publish the results of the LDAC codec testing of the MDR 1000X?
We have yet to find a reliable Bluetooth dongle that supports the LDAC codec, as it is typically only available on Sony devices. However, when we do, we will update the review accordingly, but it may take some time.
I noticed recently that the frequency response measurement for the M50x has changed considerably, I don't know exactly, but I remember seeing it differently. Were the measurements updated/corrected?
We are in the process if re-testing our old headphones against a new test bench and that's why the scores may fluctuate a bit for the next month, until they stabilize. A key feature of the new test bench is measuring the low-end of headphones on 5 human subjects, 5 times each to cover for seal/leakage issues experienced with measurement heads. The M50X was just updated.
First of all, thank you so much for this detailed review, I really appreciate it that you made a review based on measurements instead of own experience. However I do have one unanswered question, could you tell me which firmware of the Bose QC is used for this review? I am wondering about this since I have read that there are some considerable differences in sound quality between one firmware and another. Thanks in advance.
We measured the QuietComfort 35
on firmware 1.0.6. We will retest the headphones with the most recent firmware 1.2.10 and append the review with the new data and any significant changes. However, we also have a new test bench, which means we are re-measuring all our previously posted headphones, so not all the changes will be due to the firmware update. We've bumped the QC 35 in our priority queue so the review should be up-to-date in a week or two.
