Feature review · Over-ear headphones
Verdict
The Cowin E9 is a comfortable, lightweight over-ear pair with noise cancelling that blocks office noise well, though its build feels plasticky.

Third-party reviews

What customers like about Cowin E9

  • Improved Hybrid Active Noise Cancelling (ANC) that effectively blocks out engine, traffic, and office noise.
  • Superior sound quality with support for high-end audio codecs like aptX, aptX HD, and aptX Low Latency.
  • Exceptional comfort provided by upgraded protein ear pads and a lightweight, adjustable headband.
  • Long battery life offering up to 30 hours of playtime on a single charge.
  • Clear call quality using CVC HD noise-canceling microphones.
  • Excellent value for the price, often compared favorably to more expensive models.

What customers don't like about Cowin E9

  • Long-term durability concerns, with some reports of the exterior coating tearing or parts breaking after several months.
  • Ear pads are not easily replaceable, requiring a difficult gluing process for third-party replacements.
  • Charging time is relatively slow at 4 hours compared to newer competitors.
  • Some users find them slightly less comfortable than the preceding SE7 model.
  • Potential for audio cutouts during vigorous physical activity like jumping or intense exercise.
  • The 30-hour battery life, while good, is surpassed by many modern alternatives in the same price range.

Verdict

The Cowin E9 is an over-ear wireless headphone featuring advanced hybrid active noise cancellation (ANC) technology with a depth of -33dB and a five-microphone system for clear CVC HD calls. It is equipped with 40mm large-aperture drivers, Bluetooth 5.0 for stable connectivity up to 15 meters, and broad codec support including aptX, aptX HD, aptX Low Latency, and AAC for high-fidelity audio. Key pros include a substantial 30-hour battery life from an 800mAh battery, a comfortable foldable design with protein ear cushions, and a frequency response of 20Hz–20kHz. Notable cons include a relatively long charging time of approximately 4 hours and reports of potential long-term durability issues with the exterior coating and ear pads.
