? COWIN E7, an over-ear Bluetooth headphone with Active Noise Cancelling technology and a huge number of happy customers.

COWIN might not be a brand that you have heard too often due to their young age. Nonetheless, the brand has skyrocketed with the sales driven by their COWIN E7, even becoming one of the top 5 most sold headphones at Amazon with more than 7000 highly positive customer reviews, a quantity above some extremely popular headphones such as the: Beats Solo2, BOSE QuietComfort 35, Audio Technica ATH-M50X, Kingston HYPERX CLOUD II, Sennheiser HD598, Beats Studio WirelessBose QuietComfort 25, to name a few. With such a large number of satisfied owners we decided to find out why they gained such a reputation and submit them to our COWIN E7 soundtests to see if they hold up to our reader’s standards.

The COWIN E7 features 40 mm dynamic drivers, Bluetooth wireless connection, NFC and Active Noise Cancelling (if you buy the COWIN E7 ANC model). The construction of this Bluetooth headphones is made of a combination of metal and plastic parts; the headband has a reinforced metal band and most of the details of the earcups, despite seeming metal, are made of silver colored plastics. Overall, they feel substantially tough and durable and give the impression to be less fragile than many Sennheiser headphones.

The cups of the COWIN E7 are rounded and fairly large allowing them to fit your ears inside the pads (over-ear headphones). The depth offered by the ear cups and the ear pads makes them very comfortable with the ears not touching the structure of the ear cups.

The COWIN E7 is compatible with Android and Apple devices.

You can buy the COWIN E7 in black, blue, white or red color and you can choose among 2 different models:

Accessories & Packaging

The COWIN E7 unboxing results in a micro USB charging cable, a detachable 3.5 mm audio cable for wired usage and a soft carrying pouch. Everything comes inside a hard packaging that protects them well.



Bass & Sub Bass

Active Noise Cancelling Off / Bluetooth On

The COWIN E7 bass is very rich with decidedly punchy mid-bass and sufficiently profound sub-bass. Mid-bass can be overwhelming unless you are really into heavy-bass headphones.

Applying an EQ, their mid-bass and sub-bass get insanely empowered, making them reach a respectably entry-level basshead rumble and impact that will massage your ears and nearby areas (advanced basshead EQ skills are needed to reach this level of impact).

The score of 8/10 that they are getting here is for mid-bass punch strength and basshead potential more than for bass quality.


Active Noise Cancelling On / Bluetooth On

Using the COWIN E7 in ANC mode, their mid-bass got tamed making them sound much more balanced. Their “party-styled” bass transforms into an almost conservative but not anemic style that will offer less invasive lower frequencies, when needed.

Applying an EQ in this mode can be beneficial if you set it to empower the lowest frequencies range, mostly you can feed anything below 50Hz making their sub-bass greatly deeper sounding and leaving their mid-bass as free of boomy sound as before equalizing.

The 7.25/10 that they are getting here is not for bass intensity; instead, represents a score for their non-invasive sound.


Like with every Bluetooth Headphone that we have reviewed we did not apply our extreme basshead tests to the COWIN E7 to avoid possible damage to their Bluetooth and ANC circuitry. Still, as you might have just read from the section above, the COWIN E7 are able to provide some basshead impact and rumble without the need of an amplifier like the Fiio E12 Mont BlancCayin C5, iFi micro or Mojo Chord, for example.

Mids & Vocals

Active Noise Cancelling Off / Bluetooth On

The COWIN E7 mids are very warm with strong mid-bass bleed, laid-back lower vocals and boxy sound. Higher mids are rolled off and not very crisp but this translates into 100% free of harsh peaks.

With an EQ, lower mids and lower vocals gain a total makeover, becoming much more clear sounding, remove their laid-back style and noticeably reduce mid-bass bleed but remaining warm and cozy.


Active Noise Cancelling On / Bluetooth On

With ANC turned on, mids show an important improvement of lower vocals and general lower mids thanks to a strongly less present mid-bass bleed. Still, mids sound overall warm and have a boxish style.

Using an EQ on this mode, the mids of the COWIN E7 become extraordinarily better with a clear and well resolved range, with non-congested lower vocals, crisp higher mids that do not sound neither forward nor harsh and an almost absolute removal of “boxiness”. To achieve this you will need to roll up your sleeves and get to work as it requires a custom EQ a bit more complex than usual, but we will save you a lot of work by giving you some EQ hints; dial down frequencies ranging from +/- 300Hz to 620Hz applying the strongest reduction near 400Hz. By now their mids will sound greatly better but if you want to go a step further and fine tune it a bit, play around feeding up frequencies at 1200Hz to 1800Hz but be conservative here or you will mess up their upper mids.

Take into account that the score of 5.75/10 is not considering their sound quality with the custom EQ applied, it represent the score for their non-equalized sound.



Highs & Treble

Active Noise Cancelling Off / Bluetooth On

The COWIN E7 highs are dark sound with a very small amount of detail resolved. There are no piercing highs at all and fairly low sibilance that is only perceptible with very sibilant prone songs.

An EQ adds an important extra brightness and some extra detail but still remains with a dark tint.


Active Noise Cancelling On / Bluetooth On

The overall highs of the COWIN E7 become much less muddy and noticeably more open sounding, the very dark sound from before is now better balanced yet with a dark style, this is mainly a perceptual sensation by the much less present mid-bass. Piercing and sibilant highs remain as with ANC Off.

An EQ makes their highs much brighter. The starting clearer baseline sound that they offer with their ANC ON, makes their highs bright and more open sounding with no dark tint. To achieve this, apply an EQ slightly boosting frequencies from 5kHz and above and slightly reducing those at +/-3.5kHz.

Sound Leak

The sound leaking out of the COWIN E7 is stronger than average if you set your volume above a moderate level; most probably not an issue on busy cities.

Sound Isolation

The sound isolation provided by the COWIN E7 is very noticeable even while not turning their Active Noise Cancelling. Your surroundings will get strongly subdued no matter which volume you set on your device.

Our measurements of their Active Noise Cancelling showed a maximum reduction of 22dB on their most effective reduction frequencies and averaging +/- 15dB on most of the “cancelled” range but they do not extend as much nor as strong as the Xiaomi Mi Noise Cancelling Earphones (consider that these Xiaomi earphones that we have reviewed and measured offered an active noise cancelling as strong as the BOSE QuietComfort 20, so we are confronting the COWIN E7 aganist two heavy weight champions).

Turning on their Active Noise Cancelling function, the reduction of noises such as those of airplane cabins get substantially suppressed with a level that a passive noise isolation headphone cannot offer.

The size and depth of the earpads + earcups offer a greatly comfortable fit that can embrace inside your ears without generating pressure or pain. The clamping force is secure, yet flexible to easily adapt to any head’s size without issues. Moreover, their pivoting earcups allow a perfect positioning and the 90 degree rotating system enables their earcups to lay flat when carrying them around the neck or inside the carrying pouch.

Response to Equalization

The response to EQ of the COWIN E7 was excellent, with much brighter highs in all modes, remarkably clearing up mids overall, reducing lower vocals congestion and “boxiness” (also in all modes) and making sub-bass reach an entry-level basshead impact and rumble without the need of any amplification (advanced basshead EQ knowledge is needed)
