10mm Speakers combined with Bluetooth V4.1 create premium sound with rich bass and crystal clear treble.
The upgraded version can pair with mobile phone up to 33 feet.
Long battery life allows the headphones to play up to 5 hours of continuous music at a time.(100% volume with 3H;80% volume with 4.5H;60% volume with 5H)
Thanks to the winged tips, which come in three sizes --small, medium, large, the earbud sits loosely in your ear yet remains securely in place.
The upgraded version with Bluetooth V4.1 can simultaneously pair with your mobile phone and Mac. No trouble switching between the two devices when a call came in as you were watching a video on the computer.
