I tried 4 different types of BT headsets, and this is the best. Because of the need for batteries, they have to be heavier than wired ones. Therefore the over the head design is far more comfortable, and functional too.Netagives?The buttons seem to respond slowly.Sound is a little digital sounding, but better than most I tried. State of the art is not very good in this area.Any time it gets away from the phone it has to be reassociated, which is a pain. I suspect this is a falut of the phone, not the headset. It does cause me to go back to my wired headset a lot though because you can't realistically turn it on with short notice.
