Cowin E7 Active Noise Cancelling Bluetooth Headphones With Microphone Review

Test Results

Blueprint

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

Weight 0.6 lbs

Clamping Force 1.1 lbs

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 take on some listeners. They're non especially uncomfortable, merely considering the headband is rather brusk, they will feel a flake tight on larger heads. For a more than comfortable budget headset, take a look at the Mpow H10 Wireless or the Anker SoundCore Life 2.

OS Compatibility Non OS specific

Ease Of Use Mediocre

Feedback Decent

Call/Music Control Aye

Volume Command Yep

Microphone Control No

Channel Mixing No

Dissonance Cancelling Command On/Off

Talk-Through No

Additional Controls No

The push layout for the Cowin E7 feels a bit cramped but delivers practiced feedback. They have responsive and clicky buttons for volume command, call/music, and skipping tracks. They besides take a dedicated switch to enable Bluetooth and noise cancelling. Yet, the cramped layout and the odd placement of the volume controls aren't as intuitive and may have some fourth dimension to get used to.

Avg.Temp.Difference 4.6 °C

The Cowin E7 are decently breathable for an over-ear design. They'll warm upward your ears and brand you sweat during more than intense exercises, but you lot can listen to them for longer periods without existence too bothered by the temperature divergence. 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 meliorate options.

Transmitter Required No

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 comfy when resting the headphones around the neck.

Type Pouch

L Due north/A

W Due north/A

H N/A

Book N/A

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

The Cowin E7 accept an ordinary build quality that feels a bit cheap. The headband is well synthetic 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, just the ear cups and hinges don't experience every bit durable as the more contempo Cowin SE7 Wireless or fifty-fifty some of the other budget headphones we've reviewed in this price range.

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 almost ideal headphones for running or working out. On the upside, they're wireless, so they won't get yanked off your caput because the cable got hooked on something.

Audio

Bass Amount 2.13 dB

Treble Corporeality -6.74 dB

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

Avg. Std. Deviation 0.31 dB

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

Std. Err. 2.46 dB

Low-Frequency Extension 10 Hz

Low-Bass -3.42 dB

Mid-Bass -two.12 dB

Loftier-Bass 1.72 dB

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.

Std. Err. 4.64 dB

Low-Mid one.87 dB

Mid-Mid 0.02 dB

Loftier-Mid -6.06 dB

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

Std. Err. 13.43 dB

Mid-Treble -7.04 dB

Depression-Treble -xv.86 dB

High-Treble -10.88 dB

The Cowin E7 take 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 joint of vocals and lead instruments. Mid-treble is also underemphasized, placing the overall treble tone and effulgence merely south of neutral.

Peaks two.41 dB

Dips three.26 dB

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

Weighted Group Delay 0.21

Weighted Phase Mismatch 23.26

Weighted Amplitude Mismatch 1.26

Weighted Frequency Mismatch 2.06

The imaging is decent. The maximum weighted group delay of the Cowin is 0.21, which is pretty adept. Information technology can besides be seen in the graph that the grouping delay is constantly below our audibility threshold. The ascent in the grouping delay below 20Hz isn't platonic, but shouldn't exist aural to nigh. Additionally, our exam unit showed decent matching between the L/R drivers. This helps with authentic placement and localization of objects (like footsteps, voices, instruments) in the stereo image.

PRTF Accuracy (Std. Dev.) iii.eighteen dB

PRTF Size (Avg.) 4.72 dB

PRTF Distance ix.9 dB

Openness

Acoustic Infinite Excitation

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

Isolation

Overall Attenuation -17.85 dB

Bass -7.5 dB

Mid -thirteen.23 dB

Treble -33.15 dB

The noise isolation performance of these headphones is okay but non as good as some like headsets nosotros've tested like the Anker SoundCore Infinite NC. The agile noise cancelling system achieves about 8dB of reduction in the Bass Range which is below boilerplate. This range is occupied by the rumble of plane and bus engines. In the mid and treble ranges, mostly occupied past 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. Nonetheless, these headphones are a chip on the noisy side, performing below average in our self-noise examination. Come across our recommendations for the best noise cancelling headphones.

Overall Leakage @ 1ft 38.56 dB

The leakage functioning is decent. The meaning portion of leakage sits between 300Hz and 3kHz which is a relatively wide 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. Notwithstanding, the overall level of leakage isn't likewise loud, so the leakage should not be an issue in well-nigh situations unless you blast music in a tranquillity environment.

The integrated microphone has a mediocre recording quality. Recorded speech sounds sparse and muffled, but withal comprehensible for the nigh part.

SpNR 10.72 dB

Noise Gate Always On

Oral communication + Pinkish Noise Handling

Speech communication + Pink Racket Sound Sample

Spoken communication + Subway Noise Handling

Speech + Subway Dissonance Audio Sample

The noise treatment of the mic is mediocre. In our noise treatment test, it achieved a speech-to-noise ratio of 11dB, which means these headphones volition mostly exist suitable for repose environments and will struggle to separate speech from background noise even in moderately loud environments.

Our previous Test Bench 1.iv measurements reported 'PC Latency' at 164 ms, 'iOS Latency' at 151 ms, and 'Android Latency' at 130 ms. Notwithstanding, our new test bench uses an average of three measurements instead of one, resulting in 131 ms of latency on PC, 54 ms on iOS, and 46 ms on Android. As a result, we have updated our text to better reverberate test bench i.5 measurements.

These headphones have good Bluetooth connectivity and support NFC for easy pairing with smartphones. Unfortunately, they can't pair simultaneously with multiple devices simply should be relatively easy to pair with ane Bluetooth source. Overall, their latency on PCs as well every bit Android and iOS devices is also adequately low, so you shouldn't detect delays betwixt your audio and visuals.

The E7 Pro too last a bit longer on a single charge than the regular E7, simply take considerably longer to charge, too. On the other hand, the regular E7  performs almost too in all other categories when compared to the Pro. The more bass-heavy profile too makes them a better pick for bass-lovers that want a noise cancelling wireless headset on a budget.

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 besides have easier to apply controls and a better-counterbalanced sound overall. On the other paw, the E7 have more bass, which some listeners may prefer.

Their sound profile is also much improve-balanced, with a much more accurate treble range. On the other mitt, the Cowin last longer off a single charge and have a slightly meliorate ANC characteristic, though neither headphones block very much background racket.

The Mpow H10 Wireless are better headphones than the Cowin E7 Wireless. They are more than comfortable to article of clothing for long periods of time and the padding is very soft compared to the rigid ane on the Cowin. The Cowin also take mediocre sound quality with heavy bass and treble that lacks a lot of detail. The Mpow also isolate more ambience dissonance and will be better suited for commuting.
