The Cowin E7 are a budget over-ear headphones with an excellent wireless range but a mediocre sound quality. They tend to sound a little dark and muffled but 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.
- Low leakage.
- Great wireless range.
- Mediocre-at-best sound quality.
- Slightly bulky design.

The E7 have a decent design and build quality but feel slightly cheap. They're well-padded headphones that won't be as comfortable for all listeners since their headband doesn't extend far enough to accommodate different head shapes and sizes. They're also a bit bulky and slightly tight for some listeners. On the upside, they have a good but slightly cramped control scheme, and the tight fit prevents them from being too unstable. They won't be the ideal headphones for running and working out but they should be fine for casual listening sessions and even a light jog.
The Cowin E-7 look decently stylish but don't have the best build quality. They have a thick and well-padded headband that feels more high-end than the rest of the design. The ear cups are also equally well-padded but the plastic used in their build quality feels low grade and bit cheap. They also have a glossy finish which won't be for everyone.
The E-7 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 doesn't extend far enough they will feel a bit tight on some heads.
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 are not as intuitive and may take some time to get used to.
These headphones are above-average 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 are not sports headphones, due to their bulk and size they still sway a lot during strenuous activities so they won't be the 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.
These headphones do not fold to take less space. They're on the larger side for over-ear headphones with a slightly bulky design that's not convenient to carry on your person. The ear cups do lay flat, but it doesn't save much space, so you will most likely need a bag to carry them around.
The Cowin E7 have an average 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 won't break from a few falls, but the ear cups and hinges do not feel as durable as some of the recent budget headphones we've reviewed in this price range.
The Cowin E-7 are a mediocre sounding pair of closed-back over-ear headphones. They have a deep and extended Bass and perform very consistently across multiple users. However, their Bass tends to sound boomy, their Mid Range is muddy and overpowering, and their Treble lacks a lot of clarity and detail. Additionally, they don't have the most open and spacious Soundstage, and their distortion performance is about average.
Very good Bass Range performance. Low-bass is extended down to 10Hz which is excellent. It is also slightly over our target, adding a bit of extra thump and rumble which some may like. High-bass is overemphasized by about 5dB, making the sound noticeably boomy.
Mediocre Mid Range performance. Low-mid and mid are overemphasized by up to 6dB. This is the continuation of the high-bass bump, making the sound muddy and mid-rangy. The dip in high-mid has a small negative effect on vocals/leads by reducing their clarity and intensity.
Poor Treble Range performance. Low-treble is underemphasized by more than 10dB, negatively affecting the presence and detail, especially on vocals/leads. However, treble and high-treble are relatively flat and only slightly under our target.
Excellent frequency response consistency. Due to the plush pads and small ear cups, these headphones perform very consistently in both the Bass and Treble Ranges. Even users who wear glasses should be able to get a consistent and proper Bass response, given a proper fit.
Poor Soundstage performance. Due to the shallow ear cups, these headphones don't interact with the pinna like loudspeakers or larger headphones do. Therefore, their Soundstage may be perceived to be located inside the listener's head as opposed to in-front. Additionally, because these headphones are closed-back, they isolate the listener from their environment and won't sound as open and spacious as open-back headphones.
Average Imaging. Phase error is minimal and won't be audible to most users. However, the phase mismatch in the Bass and Treble Ranges could have a minor negative effect on the stereo image of these headphones.
Average Harmonic Distortion performance. The overall amount of distortion is elevated throughout the range. However, the Treble Range doesn't seem to be affected by an increase in level, and only the Bass and Mid Ranges show an increase in distortion under heavier loads, which is good.
The E-7 have a decent isolation performance. They actively cancel ambient noise so that you can use them during your commutes without getting distracted by all the noise around you, especially if you're listening to music. They also create a sufficiently good seal around your ears that doesn't leak much, which makes them an above-average option to use in quieter settings. However, at high enough volumes, they will be audible to the people around you, and their somewhat decent isolation won't be enough for particularly noisy environments.
Average Isolation performance. The active noise-cancelling system of the E7 achieves about 8dB of reduction in the Bass Range which is below average. In the Mid and Treble Ranges, these headphones isolate mostly passively using their ear cups, achieving 13dB and 33dB of reduction in the Mid 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.
Decent Leakage performance. The significant portion of leakage sits between 300Hz and 3KHz which is a relatively broad range and it covers most of the Mid Range. However, the overall level of leakage is not too loud.

The Cowin E-7 have an excellent wireless range and a decent battery life but a relatively slow wireless connection. They will easily pair with your mobile devices as the pairing procedure is not very complicated and remembers the last sync device. They also support NFC which makes pairing even easier with mobile phones. They have a long battery life that lasts more than 24 hours of continuous playback but takes a bit of time to charge. Unfortunately, they won't be the ideal headphones for watching movies due to their relatively high latency.
The Cowin E7 have a great wireless range that's suitable for both indoors and outdoor use. In direct line of sight, they reached up to 180ft before any major connection drops, and even when the Bluetooth source is obstructed they still had an above-average range of more than 45ft. They also support NFC which makes their already pretty simple pairing procedure even easier.
These headphones have about 160ms of latency. While this is about average for most Bluetooth headphones without any additional low latency codecs, it also means they won't be ideal for watching videos.
The E-7 have a long lasting battery life but a long charge time. Although they do give you about 45 minutes of playback from a 10 minutes charge, to charge them fully, you have to leave them plugged in for more than 3 hours which is not ideal. On the upside, they can be used completely passively, and they can continue playing audio while charging. Unfortunately, they do not automatically turn off to save battery.
