Over all pleased with itHave had it cut off like other reviews have saidI think it has to do with you laying on your back.It happens when I am stretching.Also when you lay down it will hit the ground / bench so you can't wear it while bench pressing or any thing you relax your head on somethingOr it might be because I have a big head.But the sound is good & it last most off the week I charge it on Sunday night go to gym Mon Wed & Fri for music & the occasional phone call but I don't use it for any thing else & I am only using it about 45 min a day. I definitely recommend it for the gym. You don't have to worry about wires so it makes it safer & I have never had them slip off. Oh call quality is good no has told me to use the handset. I use to get that a lot w/my Samsung wep200 & Motorola h700.
