The Cowin E7 are budget noise cancelling headphones with a great wireless range but mediocre sound quality. They're decent for most uses but tend to sound a little dark and muffled. On the upside, they have a moderately comfortable design, a long battery life, and block a decent amount of noise for commuting. Unfortunately, their budget price shows in their build quality, which feels a bit cheap at times.

Our Verdict

6.4 Mixed Usage

The Cowin E7 are mediocre for mixed usage. These headphones block enough ambient noise for commuting and don't leak much in quieter settings like the office. They're not the most comfortable for all listeners, but they have a stable enough fit that they won't immediately fall off your ears if you run with them. Regrettably, they have a sub-par sound that will not be ideal for critical listening and may even sound too dark for more casual listeners.

Pros
  • Low leakage.
  • Great wireless range.
  • Good battery life.
Cons
  • Slightly bulky design.
  • Mediocre microphone.
6.0 Neutral Sound

The Cowin E7 are passable for neutral listening. They have good bass and an average mid-range but lack a good treble performance, which makes them sound a bit dark and muffled. They also have a relatively narrow soundstage due to their closed-back, noise cancelling design. They won't be the best headphones for neutral listening.

6.8 Commute/Travel

Decent for commuting. The Cowin E7 Wireless block enough noise for moderately loud environments. They don't leak much and have a decent control scheme. However, they're a bit bulky and are not the most portable headphones to carry around on your person.

6.8 Sports/Fitness

The Cowin E7 are decent for sports. They're wireless and have a tight fit on some listeners, which prevents them from easily falling off your head. However, they're a bit bulky for running and working out. They're also not as comfortable. They're a bit more breathable than most over-ears, but will still make you sweat more than usual during intense exercises.

6.5 Office

The Cowin E7 are okay for office use. They don't leak much, at relatively high volumes so you won't distract your colleagues. They also block a decent amount of ambient noise but may not be able to cancel out the chatter of a particularly lively office. Unfortunately, they're not the most comfortable headphones to wear for really long and extended listening sessions.

4.8 Wireless Gaming

The Cowin E7 aren't recommended for gaming. They have too much latency, they're not compatible with consoles via Bluetooth, and can't be customized to the extent of other gaming headphones. They also have a mediocre-at-best integrated microphone.

6.4 Wired Gaming

The Cowin E7 are mediocre for use as a wired gaming headset. Although they have well-padded ear cups and are decently comfortable, the headband is rather short and won't fit all head sizes. Latency shouldn't be an issue when they're used wired, and they have enough bass extension to produce deep thumps and rumbles. Their microphone is passable and recorded speech sounds understandable, but can come across thin and muffled.

6.0 Phone Calls

The Cowin E7 are passable for making phone calls. Speech tends to sound thin and muffled but is still understandable. The microphone should be fine in a quiet setting, but it struggles to separate speech from background noise in a noisy environment.

The Cowin E7 look decently stylish; however, they're a bit on the bulky side and their glossy finish picks up fingerprints and smudges easily.

The Cowin E7 are well-padded and decently comfortable headphones, but the headband doesn't extend far enough to accommodate all head sizes. They're relatively lightweight and the padding used for the ear cups and headband is soft, which reduces some of the clamping effect that these headphones have on some listeners. They're not especially uncomfortable, but because the headband is rather short, they will feel a bit tight on larger heads. For a more comfortable budget headset, take a look at the Mpow H10 Wireless or the Anker SoundCore Life 2.

The button layout for the Cowin E7 feels a bit cramped but delivers good feedback. They have responsive and clicky buttons for volume control, call/music, and skipping tracks. They also have a dedicated switch to enable Bluetooth and noise cancelling. However, the cramped layout and the odd placement of the volume controls aren't as intuitive and may take some time to get used to.

Breathability
Avg.Temp.Difference 4.6 C

The Cowin E7 are decently breathable for an over-ear design. They'll warm up your ears and make you sweat during more intense exercises, but you can listen to them for longer periods without being too bothered by the temperature difference. However, they won't be the most ideal headphones for sports or long listening sessions. In this case, in-ears or open-back headphones would be better options.

The Cowin E7 aren't particularly portable headphones. They're fairly large and they can't fold up to save space. The ear cups can lay flat, making them a bit more comfortable when resting the headphones around the neck.

The Cowin E7 come with a basic pouch that'll protect the headphones against minor scratches but won't shield them from impacts, drops, or water damage.

Build Quality

The Cowin E7 have an ordinary build quality that feels a bit cheap. The headband is well constructed with a metal frame for reinforcement. However, the plastic used for the ear cups feels low grade and a bit cheap. They shouldn't break from a few falls, but the ear cups and hinges don't feel as durable as the more recent Cowin SE7 Wireless or even some of the other budget headphones we've reviewed in this price range.

7.0
Design
Stability

These headphones are decently stable. They have a relatively tight fit on some heads, which means they won't move a lot during casual listening sessions and even a mild jog. However, they're not sports headphones. Due to their bulk and size, they still sway a lot during strenuous activities, so they won't be the most ideal headphones for running or working out. On the upside, they're wireless, so they won't get yanked off your head because the cable got hooked on something.

Sound
Sound Profile
Bass Amount

The Cowin E7 have a dark sound. The over-emphasis in the high-bass and low-mid introduces some muddiness, and there's a sharp dip in the high-mid and low-treble, making vocals and leads sound farther away and less detailed.

8.4
Sound
Frequency Response Consistency
Avg. Std. Deviation
0.31 dB

The frequency response consistency is great. The Cowin showed very little variance in bass delivery across our five human subjects. This could be due to their noise cancelling system, similar to what we noticed with the Bose QuietComfort 35 and the Sony WH-1000XM2. Overall, they should be able to deliver consistent bass and treble across multiple re-seats and users.

The Cowin E7 have a very good bass accuracy. They have great bass extension to produce a thumping sound, but the over-emphasis in the high-bass makes them sound a bit boomy.

The mid-range accuracy is mediocre. Low-mid is overemphasized, making vocals and lead instruments sound muddy and thick. The dip around 2kHz hurts the presence and projection of lead instruments.

The Cowin E7 have a bad treble accuracy. The overall response is rather inconsistent, which could result in an uneven treble. The lack of low-treble negatively impacts the presence and articulation of vocals and lead instruments. Mid-treble is also underemphasized, placing the overall treble tone and brightness just south of neutral.

Peaks/Dips

The peaks and dips performance is mediocre. The huge dip in the high-mid and low-treble causes vocals and leads to sound distant, and the over-emphasis in the mid and high-treble can make the headphones sound piercing on some tracks.

The imaging is decent. The maximum weighted group delay of the Cowin is 0.21, which is pretty good. It can also be seen in the graph that the group delay is constantly below our audibility threshold. The rise in the group delay below 20Hz isn't ideal, but shouldn't be audible to most. Additionally, our test unit showed decent matching between the L/R drivers. This helps with accurate placement and localization of objects (like footsteps, voices, instruments) in the stereo image.

The soundstage of the Cowin E7 is poor. The PRTF response doesn't quite follow our reference speaker's in accuracy, size, or distance. Also, due to the closed-back design and active noise cancellation, their soundstage won't feel as open and spacious as open-back headphones. The overall soundstage will be average in size, but mediocre in distance and accuracy, which may be perceived as unnatural and located inside the listener's head.

The weighted harmonic distortion of the Cowin E7 is decent. There's slightly more distortion in the treble range when listening at moderate volume levels, but it shouldn't be noticeable for most people.

The noise isolation performance of these headphones is okay but not as good as some similar headsets we've tested like the Anker SoundCore Space NC. The active noise cancelling system achieves about 8dB of reduction in the Bass Range which is below average. This range is occupied by the rumble of airplane and bus engines. In the mid and treble ranges, mostly occupied by speech, these headphones isolate passively using their ear cups, achieving 13dB and 33dB of reduction in the nid and treble ranges respectively. Both values are within decent limits. However, these headphones are a bit on the noisy side, performing below average in our self-noise test. See our recommendations for the best noise cancelling headphones.

Leakage

Overall Leakage @ 1ft
38.56 dB

The leakage performance is decent. The significant portion of leakage sits between 300Hz and 3kHz which is a relatively broad range and it covers most of the mid-range. This results in a leakage that sounds fuller and more comprehensible than the leakage of in-ears and earbuds. However, the overall level of leakage isn't too loud, so the leakage should not be an issue in most situations unless you blast music in a quiet environment.

They have a long-lasting battery life but a long charge time.

On the upside, they can be used passively even while charging.

These are budget Bluetooth headphones that support NFC for easy pairing with smartphones. Unfortunately, they can't pair simultaneously with multiple devices but should be relatively easy to pair with one Bluetooth source.

These headphones have about 160ms of latency when used with a PC, and when using them with an Android or iOS mobile device, it's generally in the same ballpark. While this is about average for most Bluetooth headphones with no additional low latency codecs, it also means they won't be ideal for watching videos. If you need to watch movies either use them wired or get the Audio-Technica ATH-M40x for their wired connection and good sound.

Compared to other headphones

Comparison picture

The Cowin E7 are average mixed usage headphones thanks to their great wireless range, good battery life, and decent noise cancelling. However, they're not the most comfortable pair of headphones compared to some of the other budget headphones we've reviewed. See our recommendations for the best headphones and the best-over ear headphones.

Cowin E7 Pro Wireless

The Cowin E7 Pro are a slightly better headset overall than the Cowin E7 Wireless. The E7 Pro have a more balanced sound profile that favors instruments and vocals, compared to the E7's more bass-heavy sound. This makes the Pro variant a bit more suitable for critical listeners. The E7 Pro also last a bit longer on a single charge than the regular E7, but take considerably longer to charge, too. On the other hand, the regular E7 delivers better value for the price, since they perform almost as well in all other categories when compared to the Pro, but are slightly more affordable. The more bass-heavy profile also makes them a better pick for bass-lovers that want a noise cancelling wireless headset on a budget.

Anker Soundcore Life Q20 Wireless

The Anker Soundcore Life Q20 Wireless are slightly better-mixed use headphones than the Cowin E7 Wireless. The Anker are quite a bit more comfortable, have better controls, feel better built, have a longer battery, and have much better ANC. On the other hand, the Cowin have a more balanced sound profile and lower overall latency.

Cowin E8 Wireless

The Cowin E8 Wireless are better noise-canceling headphones than the Cowin E7. The E8 have a better noise canceling performance and are a bit more comfortable than the E7. They also have easier to use controls and a better-balanced sound overall. On the other hand, the E7 have more bass, which some listeners may prefer. They also have a longer battery life and support NFC, so they're a bit easier to pair with your phone.

Mpow H5 Wireless

The Mpow H5 Wireless are better budget noise cancelling headphone than the Cowin E7 Wireless. The Cowin have a better noise cancelling performance and a longer battery life. The Cowin also have a lightly clearer mic and a better isolation performance overall, since they also leak a little less. On the other hand, the Mpow look and feel a bit more premium, have better and less confusing controls, and also have a more comfortable fit even if they're a little tight on the head. The Mpow also have much better sound.

Mpow H10 Wireless

The Mpow H10 are better headphones than the Cowin E7. They are more comfortable to wear for long periods of time and the padding is very soft compared to the rigid one on the E7. The Cowins also have mediocre sound quality with heavy bass and treble that lacks a lot of detail. The H10 also isolate more ambient noise and will be better suited for commuting. The only thing that the E7 have over the H10 is that their battery life is slightly longer, but it takes more time to charge. However, this doesn’t overcome the massive difference in sound quality.

TREBLAB Z2 Wireless

The TREBLAB Z2 Wireless are better headphones for mixed usage than the Cowin E7 Wireless. The TREBLAB feel more comfortable and durable, have easier to use controls, and support multi-device pairing. Their sound profile is also much better-balanced, with a much more accurate treble range. On the other hand, the Cowin last longer off a single charge, and have a slightly better ANC feature, though neither headphones block very much background noise.

Anker SoundCore Life 2 Wireless

The Anker SoundCore Life 2 Wireless are better headphones than the Cowin E7 Wireless. The Anker are noticeably more comfortable, have a slightly better-build, and their sound quality is also better and more accurate. On the other hand, the Cowin don’t get as hot as the Anker after use and don’t have an in-line microphone like the Anker. The Cowin's build has a plastic feel, and their glossy finish is fingerprint-prone.

Mixcder E9 Wireless

The Mixcder E9 Wireless are better headphones than the Cowin E7 Wireless. They are noticeably more comfortable, better built and they offer a superior sound quality. The controls are also better and the overall noise attenuation of the Mixcder is better than the Cowin. They also come with a nice hard case that protects the headphones better than the Cowin’s pouch. On the other hand, the Cowin offer more battery life and have NFC pairing, but that’s about it.
