The Cowin SE7 are average, mixed usage, closed-back headphones. They have a new design that feels more high-end than the Cowin E7 and E7 Pro. They are also quite a bit more comfortable than these previous models. On the other hand, their audio reproduction is disappointing and feels boomy and cluttered, so they’ll be better suited for bass-heavy genres. Their ANC feature isn’t the best but will do a decent job at isolating out noise, especially if you’re playing audio. On the upside, they have a great wireless range and their latency is lower than the average pair of Bluetooth headphones.

Design

Score components:
Cowin SE7 Wireless Design Picture

The Cowin SE7 are an improvement in design from the previous E7 and E7 Pro. They have a matte finish that gives them a more high-end look and they don’t feel as cheaply made as the E7 Pro, which have thin plastic and a glossy finish. The Cowin SE7 are better-built, and the padding on the cups and headband is soft and comfortable. They won’t be the best headphones for sports, as they get quite hot, but if you don’t mind that they are fairly stable on the head. They are very lightweight and don’t put too much pressure, so you’ll be able to wear them for a while. You can also use the SE7 wired with the included 1/8” TRS audio cable.

Style
Cowin SE7 Wireless Design Picture 2

The Cowin SE7 have a more polished and high-end look than the Cowin E7 and E7 Pro. The cups have a matte coating and don’t have the same glossy finish and cheap plastic feel as the older models. They are also less bulky and don’t have the same circular design. They have a small metal circle for style on each cup, but other than that they are fairly low-profile. It seems Cowin went for a design that resembles the Bose Quiet Comfort 35 II a bit. The SE7 come in different colors to suit your style: black, gold, purple, or dark green.

7.5 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
Cowin SE7 Wireless Comfort Picture
Weight : 0.6 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.
:
0.9 lbs

The new Cowin SE7 design is more comfortable than previous models like the E7. The cups and headband are well-padded and soft. These headphones are lightweight and don’t put too much pressure on your head, but still feel stable. However, the ear cups might be a bit small and uncomfortable for some people, especially if you have bigger ears. Nevertheless, most users should be able to wear these for a while before feeling ear soreness.

7.2 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.
Cowin SE7 Wireless Controls Picture
Ease of use : Average

Channel Mixing
What it is: Being able to mix audio channels directly on the headphones.
When it matters: This is most useful when using a separate chat software so that you can mix in-game audio and chat audio depending on your needs.
:
N/A
Noise Canceling Control : Yes
Talk-Through : No
Additional Buttons : No

The control scheme of the SE7 is decent, but it has certain flaws. The physical buttons are very clicky and offer good feedback, but they aren’t the easiest to use. You get common functionalities like calling, music, and volume control, which is expected. You can also skip tracks, but the controls are inverted from what you usually see on headphones, meaning that holding volume down will skip tracks forward instead of backward. Also, you’ll have to hold their power button for several seconds to power them on. On the upside, you have a separate switch for enabling and disabling ANC. However, you’ll need to remember to switch both the ANC and the headphones off, or it will drain your battery.

6.3 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:
Cowin SE7 Wireless Breathability After Picture
Avg.Temp.Difference : 6.1 C

Like most closed-back over-ears, the Cowin SE7 aren’t very breathable by design. They trap a decent amount of heat under the cups, which will make a noticeable difference in the ear temperature over time. Also, there is a warning in the manual that reminds you to take these off every 1-2 hrs in the summer heat. These headphones will make you sweat more than usual and won’t be ideal for working out.

6.1 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.

Like most over-ears, the SE7 are not very portable headphones. They have a bulky design, but thankfully the cups swivel to lay flat, which makes them easier to slide in a bag. They also fold into a more compact format, and you can put these in their soft case, which doesn’t add too much bulk.

6.5 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.

Volume : 146 Cu. Inches

The Cowin SE7 come with a soft case. This will protect the headphones from minor water exposure and scratches but won’t do much against significant impacts. It is slightly disappointing when compared to the E7 Pro hard case, but it is better than the original E7’s case.

7.5 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
Cowin SE7 Wireless Build Quality Picture

The Cowin SE7 have a better build quality than other Cowin headphones. They don’t have the same glossy finish and flimsy plastic design that of the E7. The SE7 cups feel dense and solid enough to survive a few accidental drops without too much damage. The headband is reinforced with a thin metal sheet and is still flexible enough.

7.0 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
Cowin SE7 Wireless Stability Picture

These over-ears are decently stable. They fit nicely on your head and apply enough pressure to stay in place, even when shaking your head. Their lightweight design doesn’t make them slide off when tilting your head forward or backward and should be stable enough for running. They are also wireless, which means you don’t have to worry about the headphones getting yanked off because the cable got hooked on something.

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.)
Cowin SE7 Wireless Frequency Response

The Cowin SE7 are mediocre-sounding closed-back over-ear headphones. They have a boomy bass that lacks thump and rumble, and their mid-range is overemphasized which makes the vocals and lead instruments sound thick and cluttered. Also, their treble is fairly underemphasized, and high frequencies will lack detail and presence. Overall, these headphones will be better suited for bass-heavy music and will not be ideal for vocal-centric genres.

We also noticed a big difference in bass delivery when the noise-canceling feature was turned on. The bass seemed to drop when ANC was working, and the drop is quite noticeable. Since they provide only average isolation, some may prefer not to use the ANC since it negatively affects the audio quality.

6.6 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:
Cowin SE7 Wireless 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.

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.

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
:
6.86 dB

The Cowin SE7 have okay bass performance. The low-frequency extension (LFE) of 48Hz and the 5dB underemphasis in low-bass indicates that these headphones will be light on the thump and rumble that is common to bass-heavy genres like EDM and hip-hop. Mid-bass, responsible for the body of bass guitars and the punch of kick drums, is within 1dB of our neutral target. However, high-bass, responsible for warmth, is over our neutral target by 7dB, which adds excess muddiness to the overall sound. We also noticed a significant drop in bass when using the ANC feature.

5.5 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:
Cowin SE7 Wireless Mid

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.

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
:
4.98 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
:
2.97 dB

The mid-range of the Cowin SE7 is sub-par. Low-mid is overemphasized by more than 8dB. This is the continuation of the high-bass bump and makes vocals and lead instruments sound thick and cluttered. Mid-mid is also overemphasized by about 5dB, which brings the vocals forward in the mix. High-mid is also overemphasized, but slightly less. The 8dB tilt through the mid-range is going to favor the lower frequencies.

6.4 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:
Cowin SE7 Wireless 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
:

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
:
-3.16 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
:
-6.0 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
:
-6.23 dB

The treble performance of the SE7 is average. The whole range is noticeably underemphasized, especially around 6KHz. This will have a negative effect on the detail and brightness of sibilances (S and T sounds). This will be most noticeable on vocals, lead instruments, and cymbals.

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.
7.2 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:
Cowin SE7 Wireless Consistency L Cowin SE7 Wireless Consistency R
Avg. Std. Deviation

When it matters: Shows how consistently the headphones perform after re-positioning them.
Good value: <0.5
Noticeable difference: 0.1
:
0.56 dB

The frequency response of the SE7 is decently consistent. In the bass range, the maximum deviation measured across our five human subjects is about 3dB, which is subtle but noticeable. In the treble range, up to 10kHz, the maximum deviation measured across five re-seats was about 12dB, but mostly in a narrow range around 5kHz.

8.7 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.
Cowin SE7 Wireless Group Delay Cowin SE7 Wireless 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.

The imaging is great. The weighted group delay is at 0.21, which is very low. The GD graph also shows the group delay response is almost entirely below the audibility threshold, suggesting a tight bass reproduction and a transparent treble. The jumps in group delay in low-bass won’t be very audible since they fall below the LFE of the headphones. Additionally, the L/R drivers of our test unit were well-matched in amplitude, frequency, and phase response, which is important for the accurate placement and localization of objects (voices, instruments, video game effects) in the stereo image. However, these results are only valid for our test unit, and yours may perform differently.

5.6 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.
Cowin SE7 Wireless PRTF
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.

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
:
10.68 dB
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
:
4.2
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

2.2
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 the Cowin SE7 is sub-par. The graph suggests good pinna interaction/activation, but mediocre in distance and accuracy. So the soundstage may be perceived as unnatural and located inside the listener's head. Also, due to the closed-back design and active noise cancelation, their soundstage won't feel as open and spacious as open-back headphones.

6.4 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:
Cowin SE7 Wireless 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 loud listening levels.
Good value: <0.300
Noticeable difference: 0.1
:

The harmonic distortion performance is average. The overall amount of harmonic distortion produced is relatively high, especially in the mid-range. This could make the sound of these headphones a bit impure. However, there is not a big rise in THD under heavier loads, especially in the bass range, which is good. The peaks at 5KHz could make the treble of these headsets harsh and brittle, which might be fatiguing over a long listening session.

6.6

Isolation

Score components:

The Cowin SE7 are active noise-canceling headphones with a passable isolation performance. They don’t cancel enough ambient noise to use for regular commutes, but you can play your music at higher volumes to block more noise. They also do not leak as much as much as some of the other closed-back over-ears, which makes them an above-average option to use in quieter conditions.

It should be noted that turning their ANC feature ON has a negative effect on the overall sound quality and seems to result in a noticeable drop in bass.

5.8 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 Cowin SE7 have a sub-par isolation performance, which is disappointing for ANC headphones. In the bass range, where the rumble of airplane and bus engines sits, they isolate by about 8dB, which is average. In the mid-range, important for blocking out speech, they achieved about 11dB of isolation, which is also average. In the treble range, occupied by sharp sounds like S and Ts, they reduce outside noise by about 32dB, which is good.

8.1 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.

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
:
33.3 dB

The leakage performance of the Cowin SE7 is good. The significant portion of leakage sits between 1kHz and 6kHz, which is a relatively narrow range. This results in a leakage that sounds fuller and more comprehensible than the leakage of in-ears and earbuds, but not as much as open-back headphones. However, the overall level of leakage is not too loud. With the music at 100dB SPL, the leakage at 1 foot away averages at 33dB SPL and peaks at 47dB SPL, which is just under the noise floor of most offices.

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
:
16.99 dB

The integrated microphone of the SE7 has a sub-par performance. LFE (low-frequency extension) is at 220Hz, indicating that speech recorded/transmitted with this mic will sound relatively thin. The HFE (high-frequency extension) of 3kHz results in speech that's noticeably muffled and lacking in detail. However, the recorded/transmitted speech would still be reasonably comprehensible in quiet environments, since that is mostly dependent on the 500Hz-3kHz range.

5.8 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.

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
:
8.9 dB

The noise handling of the SE7's mic is sub-par. In our noise handling test, they achieved a speech-to-noise ratio of 9dB, which means they will mostly be suitable for quiet environments and will struggle to separate speech from background noise even in moderately loud environments.

Compared to other Headphones

Cowin SE7 Wireless Compare Picture

The Cowin SE7 are average, noise-canceling, over-ear headphones that set themselves apart from the previous Cowin headphones by their new, comfortable, and well-built design. However, they have a very boomy and cluttered audio reproduction, and their ANC feature doesn’t isolate much. If you’re looking for a pair of headphones to use during your commute, check our recommendations for the best noise cancelling headphones and the best noise cancelling over-ear headphones, or if you don’t want to break the bank to get a good product, look at the best headphones under $100.

Cowin E8 Wireless

The Cowin E8 are better headphones than the Cowin SE7 model. They have a more neutral sound profile and won’t sound as boomy and cluttered as the SE7. Their isolation performance is noticeably better and their ANC does a good job at isolating against low-frequency noises like bus engine rumble. They also have a better battery life. On the other hand, the SE7 leak less and can fold in a more compact format. They also have lower latency and support the aptX codec, which means you won’t notice too much of delay when watching video content with these.

Cowin E7 Pro Wireless

If sound quality is the most important thing for you when choosing headphones, then the Cowin E7 Pro are a better option than the Cowin SE7 model. They won’t sound as boomy and cluttered, and won’t lack detail in the treble range. However, they might sound too sharp for some. They also have twice the SE7’s battery life. On the other hand, the SE7 are better-built and more comfortable headphones. This new design feels more high-end, doesn’t have a glossy finish that is fingerprint prone, and doesn’t feel flimsy.

Bose QuietComfort 35 II/QC35 II Wireless 2018

The Bose QuietComfort 35 II are better than the Cowin SE7 in pretty much every category. They are one of the most comfortable headphones we’ve reviewed so far, their ANC feature blocks an impressive amount of ambient noise, and they have a great audio reproduction. They have longer battery life and will be a more versatile pair of headphones than the Cowins. The Cowin have the edge in wireless range by a few feet, but they do have noticeably lower latency issues. They are also quite cheaper than the QC 35 II.

Mpow H5 Wireless

The Mpow H5 are better-sounding headphones than the Cowin SE7 and can also be connected simultaneously to two devices, which can be useful. Other than that, the two headphones are fairly similar in terms of controls and noise isolation. However, the Cowin seem to be a bit more comfortable, thanks to their soft padding. Their build quality seems a bit more durable, which explains their slightly more expensive price point. If sound is your biggest criteria, get the Mpow H5, but if durability and comfort are most important, the Cowin would still please most users, especially fans of bass-heavy music.

Anker SoundCore Space NC Wireless

The Anker SoundCore Space NC are better headphones than the Cowin SE7. Their ANC does a good job at isolating out background noise, making them more versatile for everyday casual use and especially for commuting. They also have an in-line microphone on their included audio cable which we expect to perform better than Bluetooth-integrated mics. On the other side, the Cowin might sound better for some, especially if you don’t use their lackluster ANC feature, which negatively affects their sound profile. They are also Bluetooth 5.0 compatible, which can give you better range and connection stability performance if your source supports it.

Conclusion

6.5Mixed 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:
Average for mixed usage. They have a boomy and cluttered sound profile that won’t be ideal for a wide variety of music genres during critical listening, and their ANC feature is quite lackluster, which won’t be ideal for commuting. They are fairly lightweight and stable on the head for sports, but the over-ear design will trap a decent amount of heat. Their decent battery life will last you for a whole workday, but they don’t isolate a lot of ambient chatter, which would have been useful at the office. Also, like most Bluetooth headphones, their latency may be slightly too high for watching videos, and their microphone won’t be great for online gaming.
6.6Critical 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.
Score components:
Average for critical listening. The Cowin SE7 have a boomy bass that lacks thump and rumble, and their mid-range is overemphasized which makes the vocals and lead instruments thick and cluttered. Also, their treble is fairly underemphasized, and high frequencies will lack detail and presence. We also noticed a significant drop in bass and overall sound quality when turning the ANC feature ON. Overall, these headphones will be better suited for bass-heavy music and will not be ideal for vocal-centric genres. On the upside, they are comfortable to wear for a while.
6.6Commute/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:
Okay for commuting. Their ANC feature isn’t the best, but it blocks an average amount of lower frequency noises like bus engine rumbles. You’ll also be able to mask more noise when playing audio. Thankfully, they are comfortable, so you’ll be able to wear these for a while, but they might get hot. Also, their bulky design won’t be very portable, but this shouldn’t be too much of a problem if you wear them around your neck thanks to the swiveling cups.
6.8Sports/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:
Decent for sports. These headphones are lightweight, and their bass-oriented sound profile can be good for staying pumped during a workout. They apply a good amount of pressure on the head to stay stable, but side movements of the head will make them wiggle off. You’ll be able to jog with these, but you might sweat more than usual since they trap heat under the ear cups.
6.8Office
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 the office. They block an okay amount of ambient chatter and reduce the noise of A/C systems well. Their battery life will also last you more than a full workday, which is good. Unfortunately, their microphone won’t be ideal to take business calls with, and they can’t connect to 2 devices simultaneously which would have been useful to switch between your phone and work computer.
6.0TV
Score components:
Mediocre for watching TV. While the Cowin SE7 have good wireless range and are comfortable headphones, their latency may be slightly too high for watching video content. However, their latency is better than most Bluetooth headphones, and they support the aptX codec, which may give you a better performance. Also, some devices and apps offer some sort of compensation, so you may not notice the delay as much with these headphones.
5.6Gaming
Score components:
Sub-par for gaming. Their sound quality is boomy and will make video games sound thick. They are decently comfortable for long gaming sessions, but their latency is too high for gaming. They also have a sub-par microphone that won’t be ideal for online gaming with friends and teammates. Even if you don’t need a microphone for single player games, these headphones won’t be a great choice for this use.
