Designed as a follow-up to the original E7 Cowin headphones, the Cowin E7 Pro improves several aspects of an already reliable headset. Though it is not the most efficient and comfortable model in this price range, it performs better than its predecessor Cowin E7 and numerous low-budget noise-canceling headphones.

Affordably priced at less than $100, these entry-level headphones feature noise cancellation capabilities for a more enjoyable listening experience and can be regarded as a decent option for the daily commute​.

Cowin E7 Pro ANC Headphones Review

1. Cowin Overview – not finished

Type: Over-ear Noise Cancelling Headphones | Bluetooth: 4.0 | Battery: 30 Hours | Charging: 4 Hours | Drivers: Dynamic | Drivers-Size: 45 mm | Weight: 385g


Cowin E7 Pro’s package includes the following:

  • USB charging cable
  • 3.5 mm jack cable
  • Compact carrying case
  • Documentation

Considering it weird that B&O’s $500 noise-canceling model Beoplay H9 3rd Gen does not include a carrying case, we’re quite grateful for the presence of a compact, rugged carrying case allowing the Cowin E7 Pro to be transported safely.

Design & Ergonomy

For a relatively affordable wireless headset that also has noise-canceling technology, the workmanship of Cowin E7 Pro appears of good quality for its price. The quality mirrors that of the standard Cowin E7 model. Overall, a rather simple and sleek design.

The Cowin E7 Pro features a standard design with round earcups. The earcups are well-made, built of metal, and have a polished, glossy texture on the exterior. Both earcups are attached to joints that adjust horizontally and vertically to the head’s shape, allowing the headphones to swivel by at least 90 degrees and be placed on your chest when worn around the neck.

The headband is reinforced with metal, padded throughout, and covered with synthetic leather. The headphone is also height-adjustable, lightweight, and easy to maneuver. The only possible vulnerability could be in the rotational joints. Other than that, Cowin E7 Pro seems to have a carefully made, high-quality construction.

As far as wearing comfort is concerned, Cowin E7 Pro ANC headphones offer a typical mainstream comfort level similar to their competitors. It has soft paddings on earcups and headband that don’t put pressure on your head or ears. Despite all the technology integrated into E7 Pro, the headphones weighing 310 grams do not lie too heavily and are actually comfortable even after prolonged wearing sessions.

On the right earcup, Cowin E7 houses a built-in microphone, a switch control that powers on the headphones and activate the ANC, and a port for a 3.5 mm analog connection.

On the outer side, the earcup has a LED and buttons for audio management; by pressing the “plus” or “minus” signs, you skip between songs; by pressing and holding the same buttons, you adjust the volume.

Unexpectedly, the LED is responsible for more than signaling the status of the headphones. By briefly pressing it, the music stops/plays back.

You can also manage phone calls with it or pair the headphones manually. The charging port and the charging LED are located on the right earcup. Unfortunately, I couldn’t find out what exactly the LED on the outside of the left earcup does. It also never lit up.

Bluetooth & Technology

Cowin E7 Pro features Bluetooth 4.0 and has a better than average stable Bluetooth connection that holds up surprisingly well, even at greater distances. Even the battery life looks fine, too, with over 30 hours of playtime.

Cowin E7 Pro has an 800 mAh battery that offers a great autonomy of up to 30 hours of use. Enough time to use the headset all day long without having to recharge it.

For a full charge, it takes 4 hours. The charging is done via the USB cable supplied by the manufacturer. Alternatively, if the battery is dead, you can use the audio cable to play music.

The wireless connection is stable. You can move up to 10 meters from the source (audio player/smartphone). The headphones are easy to pair with your device and support NFC technology.

However, as the headset only supports SBC, watching movies in Bluetooth is not manageable due to the high latency.

Noise Cancelling

The ANC mainly takes out the low frequencies. This means that background noises with a lot of bass sound brighter. Overall, the airplane’s engine’s noises are reduced considerably, thanks to the ANC system and good passive noise insulation construction.

They reduce only certain noises. Not all sounds around you will be masked out. You will not be completely cut off from the outside world. The noises that are reduced to a high-degree are the lower frequencies, the engine noises, humming or buzzing noises from appliances, and to a lower degree, people’s voices, although they are not completely suppressed.

When the ANC is on, the headphones’ sound changes minimally; thus, one could use the ANC to adjust the lower frequencies without relying on an equalizer.

Sound Quality

Improving upon the performance of E7, the most notable change in the E7 Pro is the bass response. If the E7 allowed a booming bass that sometimes seemed muddled, now the E7 Pro delivers superior bass quality for a much brighter sound.

Performance is slightly improved relative to the Cowin E7. Audiophiles will not be satisfied, but for this price, the sound reproduction remains acceptable.

Because Cowin E7 Pro are closed-back headphones, they offer a decent bass reproduction. The bass is full-bodied and forceful, the highs are pleasant and relatively well balanced. On the other hand, the mid-range instruments do not have enough precision and presence, thereby impacting the reproduction of vocals and some instruments.

Without ANC enabled, the headphones’ bass feels too strong. Though, you can offset the effect with an equalizer.

With cheap headphones, especially noise-canceling wireless models, we almost always expect to use an equalizer to correct the sound response. With Cowin E7 Pro, the bass and highs are strong enough that drown the mids.

The activation of ANC also produces a minimal, noticeable white nosie. Still, it’s still a lot quieter than most cheap ANC models we’re reviewed.


Cowin E7 Pro shows its improvements from its predecessor on where it counts, sound quality. The original Cowin E7 had a more contained sound.

The E7 Pro, however, has a more powerful sound. The upgrade from 40mm to 45mm drivers is why Cowin E7 Pro sounds considerably better and provides a broader frequency response for a crisp and more vibrant sound experience.

Improvements can be noticed when we steer our attention to battery life. Here, the E7 Pro provides you with 800 mAh instead of 750 mAh (two more hours of playtime.
