I am disappointed at the sound quality of this headset. If I turn up the volume loud enough for me to hear clearly, then my voice is garbled and full of background noise to those on the other end of the call. The only way to make my voice come across clear is to lower the earpiece volume very low.I tried Motorola support via the web, but the automatic emails I get back want the model number of the H700 - makes no sense to me.Lesson learned - I'm going back toa wired headset with a boom mic closer to my mouth.
