Upgraded version of the famous Cowin e7 active noise cancelling headphones. The proprietary 45mm large sound drivers provide crisp and powerful sound with deeper bass. The earpads are upgraded for more comfort. The headband is improved for more durable and comfortable long period of time use.
The microphone is much higher quality and BT v 4.0 provides higher quality hands free calls. The battery life is 30 hours at Bluetooth mode, great for long travel.
Pretty excellent headphones for the price if you ask me.
