This is easy to use with excellent stereo sound. It is compatible with voice command cellphones, too. Pauses music on playback when incomming call is received, and resumes after call. My phone has an excellent mp3 player, so it is great to be able to listen to it without wires - even from the other room, and it saves phone batteries. Headset also allows some other phone features from headset, like ignore call and voice announce of incomming number. Includes standard features such as volume adjust, and answer or call last number. Also, has skip to next or last song. Overall, a very good to excellent product. Comfortable on my 7 3/8 head, too. Built in Li-Ion Battery is not replaceable, which may be a future problem.
