Very good headfones.

these are just fine if you need a cheap pair of headphones. if you're buying them in hopes of getting a deal on some good earphones don't waste your time.

super excellent quality. the only issue I see. the cables are coming on the wrong side. the sweat from the neck will destroy the headphones cable. the slot for SD its great. i suppose if you only use the sd card instead of Bluetooth the battery might last more. the battery does last 8 hours

Sound is not clean.
