Headphones on. World off.
Cowin E-7 wireless headphones are engineered to sound better, be more comfortable and easier to take with you. Put them on, and suddenly everything changes. Your music is deep, powerful and balanced, and so quiet that every note sounds clearer. Even air travel becomes enjoyable, as engine roar gently fades away. No matter how noisy the world is, it’s just you and your music—or simply peace and quiet.

Key Features
- Better by design. E-7 Headphones are lightweight with pillowy-like softness on the headband and protein ear cushions, while the earcups rotate for a fine-tuned fit.
- Music minus noise. Advanced active noise reduction technology quells airplane cabin noise, city traffic or a busy office. So you can focus more on what matters—your music, movies and videos.
- Frequent flyer's delight. Fly once with Cowin Bluetooth over-ear headphones, and chances are you’ll never fly without them again. They reduce airplane roar to a whisper. It is made for a happy quiet fly.
- True-to-life sound. Precise guitars. Clear vocals. Clean bass and crisp percussion. Discover sound quality that brings out the best in your music—including subtle details you may never have noticed. Guaranteed by COWIN proprietary high quality 40mm large-aperture drivers.
