The Sony WF-1000x are decent mixed usage headphones with a few flaws. They're the only noise cancelling truly wireless headphones so far which makes them suitable for commuting. They have a high-end and durable design, they're stable enough for sports and they sound decent. Unfortunately, they have one of the worse latency performances for any Bluetooth headset and the right earbud would often drop connection regardless of range which can be frustrating.

Sony WF-1000X Design Picture

The Sony WF-1000X have a premium looking design that feels sturdy and durable. The earbuds are fairly compact but do stick out of the ears a bit compared to some other truly wireless designs like the Jaybird Run. They come with a great charging case that's a little bulky but flat, which makes it a bit easier to carry around in your pockets. They're stable and breathable enough to run with and come with multiple tip sizes and types including foam tips which should help you find a comfortable fit. Unfortunately, they have a poor control scheme and no volume buttons.

Style
Sony WF-1000X Design Picture 2

The Sony WF-1000X have a premium design that looks and feels high-end. The earbuds have a good blend of high-quality plastic and metal with a transparent tip that shows the antenna and lights up when in pairing mode. The case also has an elegant metal finish that feels durable and looks a lot more appealing than some of the other truly wireless designs like the Jaybird Run or the SoundSport Free from Bose. Unfortunately, the earbuds do stick out a bit once in your ear which may not be the ideal look for some listeners.

7.0 Comfort
What it is: Adjustability and degrees of freedom, pressure, stiffness and weight.
When it matters: When the headphones are going to be used for long durations.
Score components: Subjectively assigned
Sony WF-1000X Comfort Picture
Weight : 0.03 lbs
Clamping Force
What it is: The force that the headphones exert on your head, once you have them on. This is purely a measurement of the force applied, which does not take into account the earpad's surface area and the resulting pressure you will feel, on or around your ears.
When it matters: The tighter the headphones, the more force they put on your head. This can get uncomfortable or cause pain and soreness during long listening sessions.
:
0 lbs

The Sony WF-1000X have a pretty typical in-ear fit but thanks to a wide range of tips provided in the box, they're above-average comfortable. They come with 7 tip sizes including foam tips. The earbuds are relatively lightweight, and since they're truly wireless, there is no cable pulling on the buds which makes them less noticeable once in your ears. However, since they're in-ears, they do put a bit of pressure within your ear canal which may not be as comfortable as some of the earbud designs like the Bose SoundSport Free or the Apple AirPods. The tips are also not angled like the Jaybird Run which makes them slightly less comfortable.

6.1 Controls
What it is: The control scheme of the headphones, the number of functions provided, button layout and ergonomics as well as the quality of tactile feedback.
When it matters: If you want to control volume, pause your music or make phone calls without directly interacting with your audio device.

Noise Canceling Control : Yes
Talk-Through : Yes
Additional Buttons : Voice enabled controls

These earbuds have a mediocre control scheme with no volume control. They provide two buttons, one to end calls and pause tracks and another to cycle through noise-canceling modes. The buttons themselves are pretty clicky and have good feedback. However, the lack of functionality forces you to use your phone to turn up the volume or even change tracks, which is a little disappointing.

9.1 Breathability
What it is: How hot the headphones get when you wear them for an extended period of time.
When it matters: If you often have long listening sessions or use your headphones while doing physical activities like running or working out.
Score components:

Avg.Temp.Difference : 0.9 C

The Sony WF1000x are very breathable truly wireless headphones. Their compact in-ear design does not cause any significant temperature increase when exercising or working out. They do trap a little heat in the ear canal, but since they do not cover the ears like on/over-ear headphones, they won't make you sweat more than usual even during more intense work out routines.

9.5 Portability
What it is: The volume of space occupied by the headphones when folded into their most compact format.
When it matters: If you're often on the move and need to carry your headphones in a bag, purse , or pocket.

These headphones, like most truly wireless designs, are very compact and highly portable. They will easily fit into almost any pockets, and they are a lot smaller than the Bose SoundSport Free. Their charging case is pretty bulky. However, it is flat and won't be as noticeable in your pocket as the Jaybird Run or even the Bose.

7.5 Case
What it is: The provided carrying options to protect your headphones when transporting them.
When it matters: To prevent damaging your headphones, if you often carry them in your bag or pocket.
Score components: Subjectively assigned

H : 1.7 "
Volume : 5.5 Cu. Inches

These headphones come with a flat metal hard case that will easily protect the earbuds from impacts and drops and even mild water damage. However, the case does add a bit of bulk. But on the upside, since it's flat, it won't stick out in your pocket and it's a bit more convenient to carry around than the Bose and the Jaybird's truly wireless design.

8.0 Build Quality
What it is: Durability, material quality, cheap/expensive feel.
When it matters: When the headphones are going to be used by multiple users (classes/studios), by children, in tough conditions, on a daily basis, or for exercise.
Score components: Subjectively assigned
Sony WF-1000X Build Quality Picture

The Sony WF-1000X have a great build quality that feels and looks premium. The earbuds have a metal back plate that adds to the high-end appeal of the headphones and also makes them a bit more durable. The buds feel dense enough that they won't break from a couple of accidental drops and the case is also a sleek metal build that feels sturdy and protects the headphones fairly well. The lid has a slight lift mechanism that may be cause for concern due to wear and tear over time. Overall, the build quality feels superior to that of the Jaybird Run and on-par if not better than the SoundSport Free. They would be as good as the AirPods if the case and buds were a little more compact while keeping the level of premium design and build quality.

7.5 Stability
What it is: How the headphones are designed to prevent them from slipping off your ears or falling off your head.
When it matters: If you plan on using the headphones while doing sports or other physical activities that requires a lot of movement.
Score components: Subjectively assigned
Sony WF-1000X Stability Picture

The Sony WF-1000X have a stable in-ear fit that goes fairly deep into the ear canal. That combined with the multiple tip sizes and the truly wireless design make them pretty good for working out as they will rarely move around once in your ears. They only have one set of stability fins for listeners with slightly larger ears which is not ideal but also not really necessary in most conditions, unlike the angled earbuds of the Jaybird run which fit a little looser.

Sound

What it is: How accurately the audio is reproduced. The tests are performed with the headphones' most commonly used features enabled (noise-cancelling, wireless, etc.)
Sony WF-1000X Frequency Response

The Sony WF-1000X is an average sounding pair of closed-back in-ears. They have a consistent, extended and punchy bass, but it is a bit light on sub-bass and sounds slightly boomy. Their mid-range is also very good, but slightly overpowering bass and treble regions. Their treble is very well-balanced and even, but it is noticeably sharp and piercing on S and T sounds. Also, like most other in-ears, they don't have a large and out-of-head soundstage due to lack of interaction with the outer pinna.

8.8 Bass
What it is: Frequency Response from 20Hz-250Hz
When it matters: When the material is heavy on bass frequencies, such as those of kick drums and bass guitar.
Score components:
Sony WF-1000X Bass
Std. Err.
What it is: The amount of deviation (weighted standard error) in bass frequency response (20Hz-250Hz) as compared to a target response that would sound perfectly balanced to most people.
When it matters: When a balanced and neutral (reference) bass performance is desired.
Good value: <4dB
Noticeable difference: 0.1dB

1.77 dB
Low-Frequency Extension
What it is: The lowest frequency at which the frequency response reaches -3dB of the target response.
When it matters: Shows how extended the bass is.
Good value: <40Hz
Noticeable difference: 5Hz
:
10 Hz
Low-Bass
What it is: The average amount of over/under-emphasis in frequency response from 20Hz-60Hz.
When it matters: Kick drums and low frequency effects get their 'thump' from this range. Mostly felt than heard.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-1.93 dB
Mid-Bass
What it is: The average amount of over/under-emphasis in frequency response from 60Hz-120Hz.
When it matters: Melodic bass instruments have most of their fundamental frequencies in this range. This is where the 'body' and 'punch' of the bass sits.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-0.39 dB
High-Bass
What it is: The average amount of over/under-emphasis in frequency response from 120Hz-250Hz.
When it matters: Most instruments get their warmth and full-ness from this range. When over-emphasized, mixes tend to get muddy and boomy.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
2.51 dB

These in-ears have a very good bass. Their LFE (low-frequency extension) is at 10Hz, which is excellent. But low-bass is underemphasized by about 2dB. This means that the Sonys are able to produce low thumps and rumbles, but at a slightly lower level than our reference. Mid-bass, which is important for the punch of bass and kick instruments, is virtually flat and flawless. High-bass, however, shows a 3dB bump which could add a bit of boominess to the sound. Overall, the bass of the Sony is deep and well-extended, but a bit light on sub-bass and a bit boomy sounding.

8.4 Mid
What it is: Frequency Response from 250Hz-2KHz
When it matters: When the material is heavy on mid-range frequencies. This is the case for the majority of audio content.
Score components:
Sony WF-1000X Mid
Std. Err.
What it is: The amount of deviation (weighted standard error) in mid frequency response (250Hz-2.5KHz) as compared to a target response that would sound perfectly balanced to most people.
When it matters: When a balanced and neutral (reference) mid performance is desired.
Good value: <4dB
Noticeable difference: 0.1dB
:
2.15 dB
Low-Mid
What it is: The average amount of over/under-emphasis in frequency response from 250Hz-500Hz.
When it matters: Most instruments have their fundamentals or low harmonics in this range. Over-emphasis in this range sounds muddy and cluttered. Under-emphasis, thins out the vocals and lead instruments.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
2.71 dB
Mid-Mid
What it is: The average amount of over/under-emphasis in frequency response from 500Hz-1KHz.
When it matters: This range is occupied mostly by upper harmonics. Over-emphasis sounds forward and boxy. Under-emphasis pushes instruments to the back of the mix.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
1.0 dB
High-Mid
What it is: The average amount of over/under-emphasis in frequency response from 1KHz-2KHz.
When it matters: Most instruments, especially vocals, get their intensity and clarity from this range. Over-emphasis sounds honky and harsh, under-emphasis sounds weak and distant.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
0.34 dB

The mid-range of the Sony WF-1000X is pretty good. Low-bass shows about 3dB of overemphasis, which is actually the continuation of the high-bass bump. This makes the body of vocals and lead instruments a bit thick. Mid-mid and high-mid are flat but rather uneven. Overall, the mid-range of the Sony is a bit muddy and cluttered sounding.

8.0 Treble
What it is: Frequency Response from 2KHz-20KHz
When it matters: When the material is heavy on high-range frequencies, such as voice, cymbals, and any other material where brightness, brilliance and airiness is desired.
Score components:
Sony WF-1000X Treble
Std. Err.
What it is: The amount of deviation (weighted standard error) in treble frequency response (2.5KHz-20KHz) as compared to a target response that would sound perfectly balanced to most people.
When it matters: When a balanced and neutral (reference) treble performance is desired.
Good value: <4dB
Noticeable difference: 0.1dB
:
3.41 dB
Low-Treble
What it is: The average amount of over/under-emphasis in frequency response from 2KHz-5KHz.
When it matters: Almost all instruments rely on this range for their presence, detail, and articulation. Over-emphasis can sound harsh and painful. Under-emphasis hurts the comprehensibility of vocals and lead instruments.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-0.35 dB
Mid-Treble
What it is: The average amount of over/under emphasis in frequency response from 5KHz-10KHz.
When it matters: This is the sibilance range. Cymbals, vocals, and lead instruments rely on this range for brightness and presence. Over-emphasis sounds piercing and painful, under-emphasis sounds dull and lispy.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-1.57 dB
High-Treble
What it is: The average amount of over/under-emphasis in frequency response from 10KHz-20KHz.
When it matters: This range gives brilliance and airiness to the sound. Over-emphasis sounds hissy, under-emphasis sounds closed-up and lifeless.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-1.15 dB

The Sony WF-1000X have a very good treble. Low-treble is flat and within 0.5dB of our target, which is excellent. However, there is a 12dB bump around 10KHz which is going to make the sound of these headphones noticeably sibilant. Overall, their treble is well-balanced and detailed, but could sound sharp and piercing on S and T sounds.

Raw Frequency Response
What it is: The average uncompensated frequency response of the headphone. For in-ears and earbuds, this corresponds to the average of 5 measurements/re-seats on the dummy head (HMS). For over/on-ear headphones, this corresponds to the average of 5 measurements/re-seats on the HMS (Head Measurement System) for the mid and treble ranges, and 5 measurements/re-seats on 5 human subjects for the bass range.
When it matters: This is for those who want to see the raw and uncompensated frequency response of the headphone. Some of the more advanced users, are able to read and evaluate headphone frequency response in its raw form and without compensation. This will be especially useful to them if they have their own headphone compensation/target curve, which may differ from the compensation curve/target response used by RTINGS.com.
Score components:
9.1 Frequency Response Consistency
What it is: The amount of deviation of each frequency response pass, from the average frequency response.
When it matters: Shows how consistently the headphones perform after re-positioning them.
Score components:
Sony WF-1000X Consistency L Sony WF-1000X Consistency R
Avg. Std. Deviation
What it is: The average amount of deviation in frequency response of 5 re-seats, from the average frequency response.
When it matters: Shows how consistently the headphones perform after re-positioning them.
Good value: <0.5
Noticeable difference: 0.1
:
0.19 dB

The frequency response consistency is excellent. Assuming the user is able to achieve a proper fit and an air-tight seal using the assortment of tips that come with the headphones, they should be getting a consistent bass and treble delivery with each re-seat.

9.0 Imaging
What it is: 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, and how transparent the imaging is.
When it matters: When accurate positioning of the objects in the stereo image, and clear and transparent imaging is desired.
Sony WF-1000X Group Delay Sony WF-1000X Phase Response
Weighted Group Delay
What it is: The average amount of group delay calculated based on a perceptual weighting filter. Group delay indicates how long it takes for each frequency to reach their maximum amplitude. This is a monaural quality and can be perceived even with one ear.
When it matters: Headphones with lower group delay have more transparent imaging and a tighter bass. Headphones with higher group delay in the bass range tend to have a wimpy and loose bass, and headphones with higher group delay in the treble range tend to have a less transparent imaging.
Good value: <0.5
Noticeable difference: 0.1

Weighted Amplitude Mismatch
What it is: The Left/Right balance of our test unit, that is, the amount of amplitude difference between the left and right drivers. This is not a design test, but a marker for manufacturing tolerance and ergonomics.
When it matters: When a properly balanced stereo image and low manufacturing tolerance is desired. A poor score indicates a noticeable difference in level between the left and right drivers.
Good value: <1.5
Noticeable difference: 0.1

What it is: The amount of difference (Std. Err.) between the phase response of the left and right drivers of our test unit. This is not a design test, but a marker for manufacturing tolerance and ergonomics.
When it matters: When an even and stable stereo image, as well as a low manufacturing tolerance is desired. A poor score indicates there may be inaccuracies in the stereo image reproduction at certain frequencies.
Good value: <16
Noticeable difference: 3
:
2.36

The imaging of the Sony WF1000X is excellent. Their weighted group delay is 0.09, which is among the lowest we have measured. The graph also shows that the entire response is below our audibility threshold. This ensures a tight bass and transparent treble reproduction. Also, the L/R drivers of our test unit were very well-matched. This indicates accurate localization and placement of objects (voices, footsteps, instruments) in the stereo field.

1.3 Soundstage
What it is: 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.
When it matters: When an accurately produced, large and spacious soundstage, similar to that of a stereo loudspeaker setup is desired.
PRTF Accuracy (Std. Dev.)
What it is: The standard deviation of the PRTF (Pinna-related transfer function) of the headphones compared to a reference loudspeaker's PRTF at 30°. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters: An accurate pinna activation is mainly responsible for how natural and speaker-like the soundstage is perceived to be. The less error in the shape of the PRTF, the more natrual and speaker-like the perception of the soundstage will be. High amounts of error may indicate a soundstage that is unnatural or odd.
Good value: <2.5
Noticeable difference: 0.1

PRTF Size (Avg.)
What it is: The average amplitude of the PRTF (Pinna-related transfer function) of the headphones compared to that of a reference loudspeaker's PRTF at 30°. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters: This value is responsible for the perceived size of the soundstage. The higher the value, the larger the perceived size of the soundstage. However, values above the reference (5.0dB) could result in a soundstage that is perceived as unnatural or odd.
Good value: >3.7

PRTF Distance
What it is: The depth of the "10KHz notch" of the headphone's PRTF, which is caused by phase cancellations at the concha. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters: This value is mainly responsible for the perceived distance and elevation of the soundstage. A small distance value may result in a soundstage that is perceived to be located inside the head. Larger values may help pull the soundstage out from inside of the head and bring it to the front.
Good value: >13
Noticeable difference: 1
:
N/A
Openness
What it is: How open the headphones are, and how open and spacious they sound. This quality is monaural and can be perceived even with one ear. This test differentiates between acoustically and electronically produced crosstalk and only takes the acoustically generated crosstalk into account. This value is the inverse of the Noise Isolation test score, and could be indirectly related the acoustic impedance of the headphones.
When it matters: When a headphone with a sense of an open, and spacious soundstage is desired. A value of 10 indicates a fully open headphone, and a value of 0 indicates a fully closed headphone.
Good value: >7.5
Noticeable difference: 0.5
:
3.3
Acoustic Space Excitation
What it is: How loud the headphones are, and how much they excite their environment acoustically. If the headphones are loud and open enough, the sound leaking from the headphones will be affected by the environment (reflections/reverb) before reflecting back into the open headphones and to the listener's ears. This quality is monaural and can be perceived even with one ear. This value is the inverse of the Leakage test score.
When it matters: Headphones with higher excitation values, similar to openness, tend to have soundstages that are perceived as more open and spacious.
Good value: >7.5
Noticeable difference: 0.5
:
1.9
Correlated Crosstalk
What it is: How strong and solid the phantom center is. This is mostly a stereo quality and its effects on mono content are minimal. This test is sensitive to the phase of the crosstalk and whether it is produced acoustically or electronically.
When it matters: When a true reproduction of the stereo image is desired. A value of 0 indicates no crosstalk, or that the existing crosstalk is not correlated enough to affect the phantom center. A negative score means the crosstalk is out of phase with the original signal, resulting in a slightly wider stereo image at the expense of creating a 'hole' at the center of the stereo field. A positive score means the crosstalk is in phase and positively affecting the phantom center.
Good value: >1dB
Noticeable difference: 0.3dB
:
0.0 dB

The soundstage of these in-ears, like most other headphones, are poor. Since creating a large and out-of-head soundstage is dependent on a good pinna (outer ear) activation, in-ears such as these ones end up with a small and inside-the-head soundstage. Also, because of their closed-back design, their soundstage won't feel as open as open-back earbuds such as the Apple AirPods and the Bose SoundSport Free.

6.3 Total Harmonic Distortion
What it is: The subtle, unwanted frequencies (harmonics) produced alongside the intended frequencies.
When it matters: When clean and pure sound reproduction is desired, though its effect is not as noticable as frequency response.
Score components:
Sony WF-1000X Distortion
Weighted THD @ 90
What it is: The overall amount of harmonic distortion measured at 90dB SPL. To make the score more perceptually relevant, more weight is given to the higher frequencies.
When it matters: How pure the sound is at moderate listening levels.

Weighted THD @ 100
What it is: The overall amount of harmonic distortion measured at 100dB SPL. To make the score more perceptually relevant, more weight is given to the higher frequencies.
When it matters: How pure the sound is at loud listening levels.
Good value: <0.300
Noticeable difference: 0.1
:
41.51

Mediocre harmonic distortion performance. The amount of harmonic distortion in the bass range is low and within very good limits. This suggests that they should be able to take a good amount of EQ boost in the bass range before distorting. However, the spikes in THD between 1KHz and 2KHz could make the sound of that region (vocals/leads) a bit harsh and brittle.

7.2

Isolation

Score components:

The Sony WF-1000X have a decent isolation performance and are the first truly wireless design with active noise canceling. They should isolate enough for most commuters and have an aware mode which is better suited for runners that need to monitor their environment. However, noise cancellation, although decent, isn't as good as some of the other in-ear/earbuds with ANC like the Bose QuietControl 30 so they will let in some ambient noise in louder environments. On the upside, they barely leak so you can turn up the volume to mask some of the noise without distracting those around you with leakage.

6.7 Noise Isolation
What it is: How much outside noise is blocked out by putting the headphones on.
When it matters: If the headphones are going to be used in a noisy envinronment (airplane, subway, etc.)
Score components:

The ANC (active noise cancellation) performance of the Sony WF-1000X is about average. In the bass range, where the rumble of airplane and bus engines sit, the total isolation is about 9dB, which is decent. But some other in-ears like the JBL Free, Jaybird X3, Run, and Beats BeatsX achieve similar results with passive noise isolation. In the mid-range, which is important for cancelling out speech, the Sony achieves a good 22dB of isolation. In the treble range, where sharp and S and T sounds sit, they isolate by more than 30dB, which is good. It also seems that the ANC system hurts the passive isolation of the headphones in the treble range especially around 3KHz.

8.4 Leakage
What it is: The amount of sound bleeding out of the headphones.
When it matters: When the listener doesn't want people around them (in office, recording studio, etc.) to hear what is being listened to.
Score components:
Sony WF-1000X Leakage
Leakage Audio
What it is: The simulated sound leakage heard 1 foot away from the user, while the user is listening to a 100dB SPL signal. This recording is created using an EQ and is not an actual recording.
When it matters: When you don't want people hear what you are listening to.
:
Overall Leakage @ 1ft
What it is: The amount of sound leakage heard 1 foot away from the user, while the user is listening to a 100dB SPL signal.
When it matters: When you don't want people hear what you are listening to.
Good value: <35dB
Noticeable difference: 1dB
:
31.73 dB

The leakage performance of the Sony WF-1000X is very good. Like most other closed-back in-ears, the significant portion of the leakage is a narrow range in the treble section. The level of the leakage is quiet as well. This makes the leakage of these headphones barely audible, even at loud volumes.

5.6

Microphone

What it is: The microphone section shows the quality of speech capture and transmission by the mic, as well as how well the microphone under test handles noisy environments.
When it matters: For your speech to be transmitted to and understood properly by the listener, the microphone needs to have a good recording quality. If the environment the microphone is being used in is noisy, a microphone with a good noise handling performance would be needed as well.
Score components:
Integrated
What it is: The microphone integrated in the ear cup or ear bud of a wireless headphone.
When it matters: For calls, gaming and voice over IP software or for any other use of the microphone.
Good value: Yes
:

Detachable Boom
What it is: A boom mic that is detachable from the headset.
When it matters: If you want to use your headphone outdoors without the bulk and hassle of the Boom mic.
:
N/A

The performance of the integrated microphone is sub-par. Speech recorded/transmitted with the mic of the Sony will sound relatively thin and quite muffled. This could make the speech a bit difficult to understand. They also struggle in noisy situations and they may have difficulty separating speech from ambient noise even in moderately loud environments, such as a busy street.

5.2 Recording Quality
What it is: Microphone recording quality shows how natural, neutral, extended and intelligible speech would be with the device under test, in a quiet environment.
When it matters: A microphone with a good recording quality ensures that the person listening to you would hear a full, clear, and easily understandable speech. Therefore, it is important whenever a good quality of speech transmission and intelligibility is needed.
Score components:
Sony WF-1000X Microphone Frequency Response
Recorded Speech
What it is: Actual audio recording of the headphone's microphone, recorded while placed on the dummy head, with speech being played back through the dummy head's mouth simulator.
When it matters: When a clean, full, and intelligible speech transmission is required.
:
LFE
What it is: Low-frequency extension shows how deep the bass response of the microphone is, and therefore, how deep and full your voice would sound to the listener. It is the lowest frequency at which the frequency response reaches -3dB of the target response.
When it matters: LFE is not a big factor in speech intelligibility and even speech recorded with a mic that has an LFE of 500Hz could still be easily understood. Therefore, it is mostly important if you are concerned with how deep and full your voice would be heard.
Good value: <150Hz
Noticeable difference: 30Hz
:
239.73 Hz
FR Std. Dev.
What it is: Frequency Response Standard Deviation shows how accurately and balanced sound is captured by the microphone at each frequency. FR Std. Dev. is calculated between LFE and HFE, and the rest of the spectrum is ignored.
When it matters: A good frequency response is desired when a natural and neutral speech quality is desired. As opposed to HFE which is more a metric for speech intelligibility, frequency response could be considered as a metric for a natural and neutral sound.
Good value: >3.5dB
Noticeable difference: 0.5dB
:
4.75 dB
HFE
What it is: High-frequency extension is the highest frequency at which the frequency response reaches -3dB of the target response. It shows how extended the treble response of the microphone is.
When it matters: HFE is one the most important factors in speech intelligibility. The higher the HFE, the brighter, more open, and more extended the speech quality will be which makes it a lot easier to understand by the listener.
Good value: >8KHz
Noticeable difference: 1KHz
:
1684.1 Hz
Weighted THD
What it is: The unwanted frequencies (harmonics) produced alongside the intended frequencies, which cause deformation of an output signal compared to its input.
When it matters: When clean and pure sound reproduction is desired, though its effect is not as noticable as frequency response.
Good value: <1.5
Noticeable difference: 1.0
:
13.726
Gain
What it is: Shows how much louder the microphone can go above our reference loudness level. The gain value is reported relative to our reference level, which is 94dB at a distance of 5cm from the mouth.
When it matters: A microphone with a high gain is important when the input signal (speech) is very quiet. For example when whispering, or talking on the phone in a library.
Good value: >18dB
Noticeable difference: 3dB
:
39.67 dB

Sub-par recording quality. LFE (low-frequency extension) is at 240Hz, indicating a thin sound. The HFE (high-frequency extension) of 1.7KHz means that speech recorded/transmitted with the mic of the Sony WF-1000X will sound muffled and lacking presence. This will have a negative effect on the intelligibility of recorded/transmitted speech.

6.0 Noise Handling
What it is: How well the microphone is able to separate speech from background noise, so that the transmission would include more voice and less noise.
When it matters: When a clean and intelligible speech transmission is desired in a noisy situation like talking on the phone on a busy street or on the bus.
Score components:
Sony WF-1000X SpNR
Speech + Pink Noise :
Speech + Subway Noise :
SpNR
What it is: Speech to Noise Ratio is the difference in level between speech and background noise as heard by the listener
When it matters: If the microphone is going to be used in a noisy environment, it is important for it to be able to separate the speech from background noise, so the voice would be easily audible and understandable.
Good value: >24dB
Noticeable difference: 3dB
:
12.05 dB

The noise handling capabilities of the Sony WF1000X's mic is mediocre. In our test, they achieved a speech-to-noise ratio of 12dB, which is below average. This means that this microphone is only suitable for quiet environments and may struggle to isolate speech from noise even in moderately loud environments.

5.3

Active Features

What it is: Headphones with active components that require a battery. This includes noise cancelling and wireless headphones that actively reduce noise or transmit audio via a wireless connection.
When it matters: How suitable the power and wireless specifications of an active headphone will be, depending on your listening habits. The range and/or discharge time of the active headphone you select will be important if you're often on the move or have long uninterrupted listening sessions.
Score components:

The Sony WF-1000X have a below-average battery life but a great app that offers a good amount of customization options. They last about 3 hours, but a bit less if you're using the active noise cancellation. They have an additional 6 hours in the case for a total of 9 hours of playback if you take breaks. They won't be ideal for more heavy users but on the upside, they have a better companion app than most other truly wireless designs that give you EQ presets, as well as adaptive sound control and noise canceling aware mode options.

5.2 Battery
What it is: The power source of your headphones. All headphones with active features have a battery that will deplete over time.
When it matters: To continue using the active features of your headphones. Some models lose features or switch off completely when the battery is drained, which limits what you can do with them until the next charge.
Battery Type
What it is: The type of battery that the headphones use. Usually AAA or embedded, Li-ion rechargeable batteries.

:
No
Passive Playback
What it is: Active headphones that still work when all their active features are turned off or out of power.
When it matters: If you run out of power and do not have spare AA/AAA batteries or access to a power source to recharge your headphones.
:
No

The Sony WF-1000X have a sub-par battery life. They have less than 3 hours of continuous playtime, especially when using the active noise canceling feature with adaptive sound enabled. This makes them a bit worse than most of the other truly wireless designs but on the upside, the charging case has 2 additional charges totaling in 9 hours of battery life if you take breaks. This should be decent enough to last you through the day but won't be ideal for more heavy users with long listening sessions.

7.0 App Support
What it is: The additional app provided to enhance your listening experience. They typically deliver a set of practical features that give you more control over the sound, noise cancelling and effects that the headphones produce.
When it matters: An app with a lot of features allows you to customize your listening experience to suit your taste and preferences. For example, additions like an equalizer can give you more bass or treble and room effects can simulate a bigger Soundstage in closed back headphones.

These in-ears support the Sony| Headphones Connect app which gives them a bit more control over their active features and more customization options than some of the other truly wireless designs. The app is easy-to-use and provides adaptive sound profiles for when you're walking or standing still as well as different noise canceling options. You also get EQ presets but unfortunately, it's not a parametric equalizer like on the WH-100XM2. You can't make your own custom EQs and there are no room effects which is why the app has a slightly lower score for these headphones.

2.6

:
62 ft

The Sony WF-1000X has a decent wireless range but an unreliable wireless connection. They reached up to 31ft when the source was obstructed but performed much worse in direct line of sight than most Bluetooth headphones. The right earbud would also frequently lose connection and would be very unreliable regardless of the distance from the Bluetooth source. This seems more like a poor implementation of the truly wireless design than the wireless range of the headphones.

Compared to other Headphones

Sony WF-1000X Compare Picture

The Sony WF-1000x are great looking and well-built truly wireless headphones. They're one of the only truly wireless design with active noise cancellation which makes them bit better suited for commuters. However, they have a relatively short battery life, a decently balanced but slightly sharp sound quality but a terrible latency performance which makes them one of the worst headphones for watching videos.

Bose SoundSport Free

The Sony WF-1000X are a slightly better truly wireless option than the Bose SoundSport Free, but not by much. The WF-1000X have an in-ear fit and isolate much better in noisy conditions which makes them a bit more versatile for commuting and different environments. They also have a more polished and premium looking design and come with a great case but do not feel as durable as the Bose. The SoundSport Free, on the other hand, have a much better balanced sound quality that does not need an EQ for most listeners. They also have a more comfortable earbud fit that you can wear much longer than the Sony's. Their open fit is also a bit more suitable for outdoor runners since it lets you monitor your environment for traffic and obstacles but also block a lot less ambient noise.

Sony WF-SP700N

The Sony WF-1000X are slightly better headphones overall when compared to the WF-SP700N. They are both noise canceling, truly wireless in-ears but the WF-1000x have slightly better isolation although not by much. The WF-1000x also have a better and more premium looking build quality that most will prefer over the plasticky design of the SP700N and a better default sound quality that's not as bass-heavy but does sound a bit sharp. On the upside, the SP700N sound a bit more exciting out of the box. They also have slightly lighter and more unique design that some will prefer over the WF-1000X. 

B&O PLAY E8

The Beoplay E8 are a slightly better truly wireless headset than the Sony WF-1000X. The E8 have a more compact and portable design and a better charging case. The E8 also have a better latency and a more balanced default sound that you can customize thanks to the Beoplay app. They also isolate a little better than the WF-1000x despite not being the noise canceling. On the other hand, since the WF-1000x have ANC, they do a bit better against low-frequency noise like the rumbling sounds of an engine.  

Samsung Gear IconX

The Samsung Gear IconX are a much better headphone than the Sony WF-1000X. The Gear IconX isolate better in noisy environments despite not having ANC like the Sonys. They also have more features that make them better for sports than the WF-1000X. They're also more portable than the Sonys and have a better latency performance. The Sonys on the other hand, have a better more premium looking build quality. Their noise cancellation also does a bit better in the bass range than the IconX and their app is slightly more customizable than that of the IconX.

Bose QuietControl 30

The Bose QuietControl 30 are a much better wireless noise-canceling headset than the Sony WF-1000X. The QC 30 have a more comfortable earbud fit, better noise isolation performance, better sound quality and a longer battery life and wireless range than the Sonys. They also have a better latency performance, although both headphones would not be the ideal choices for watching a lot of video content. On the upside, the Sony WF-1000X are a lot more compact than the Bose and will more easily fit into your pocket despite their fairly large charging case. The Sony also have a slightly more premium looking truly wireless design which some will prefer over the Bose even if their wireless connection is not as stable.

Jaybird Run

The Jaybird Run are slightly better truly wireless headset than the Sony WH-1000XM2. The Run have a more comfortable and stable fit for the gym than the Sonys. They also have a much more customizable sound that you can fully EQ, unlike the Sonys which only have presets. The Jaybird also have a much better latency performance although they won't be the best headphones for watching videos since their latency is also fairly high. On the upside, the WF-1000X have better build quality and more premium looking design. They also come with a more portable and sturdy case that also supports NFC pairing. The Sony also isolate more in noisy conditions with their more typical in-ear fit, and active noise cancellation though their ANC is not that strong and should not be the defining feature for getting these headphones.

Apple AirPods

The Apple AirPods are also well-built truly wireless headphones with a decent sound and a good set of active features. They have a much better latency performance, which makes them somewhat OK when watching videos, especially on iOS devices. However, they lack a bit of bass due to their open fit, they're not as stable and they're more optimized for iOS. They won't be as good as the Sonys for Android users. If you 're not going to be watching a lot of videos, the Sony WF-1000x could be a decent option but the AirPods have a way more reliable Bluetooth connection and should be your first choice.

Conclusion

6.8Mixed Usage
What it is This is the combination of the different use cases to evaluate how versatile the headphones are. Therefore an everyday headphone should be well-rounded enough to adapt to most situations and environments without significant losses in sound quality, design ergonomics or isolation.
Score components:
Decent for mixed usage. They're good for sports and decently comfortable. They're also one of the only truly wireless headphones with active noise cancellation which makes them suitable for commuting. Unfortunately, they have an unreliable wireless connection which has a lot of latency. They won't be ideal for home theater and gaming but should be okay for most other use cases.
7.1Critical Listening
What it is The level of audio fidelity a headphone can reproduce. Therefore a balanced and true representation of bass, mids, treble, soundstage and imaging, as well as a comfortable listening experience, is essential for critical listening.

Average for critical listening. The Sony WF-1000X have a decently well-balanced audio reproduction. They have a good amount of bass but can sound a bit boomy and slightly sharp due to the peak in the higher frequency range. They also do not have the best soundstage since they're closed back in-ears.
7.2Commute/Travel
What it is How well the headphones handle the loud environments involved in commuting or traveling. Therefore your listening experience should be comfortable, hassle-free and as isolated from noise as possible.
Score components:
Above-average for commute and travel. They have active noise canceling which is rare for a truly wireless design. That combined with their in-ear fit isolates enough for most noisy commutes. Unfortunately, they do not have the best control scheme and they have a relatively short battery life.
7.8Sports/Fitness
What it is How well-adapted the headphones are, to use while doing sports or strenuous exercise. Therefore the headphones should not be too cumbersome and deliver a stable and comfortable listening experience.
Score components:
The Sony WF-1000x are good breathable and stable headphones for sports. They're compact, truly wireless and come with a large variety of tips to help you find a comfortable fit that stays put while you exercise. Unfortunately, they have a poor control scheme and a spotty wireless connection.
6.9Office
What it is How well the headphones can deliver a comfortable and isolated listening experience in an office-like environment. They should not leak much and should block the noise of a busy office.
Score components:
Decent for office use. They block a good amount of ambient noise and don't leak much so you can play your music at higher volumes. However, they have a relatively short battery life and a fairly typical in-ear fit which might not be ideal for really long listening sessions.
5.3Home Theater
Score components:
Sub-par for home theater. They have way too much latency for watching videos. They also have no wired option to alleviate some of the latency issues which makes them considerably worse.
4.6Gaming
Score components:
Poor for gaming. They have very high latency which is a deal breaker for this use case. They also have a sub-par microphone and aren't as customizable as most gaming-oriented headsets.
