We have 2 H-700s, and were very pleased with the ease of set-up, and the overall quality of the device.Voice quality incoming and outgoing seem to be very good- nobody tells you it sounds like you're in a cave!The only down-side we've experienced is fairly short battery life. No, I haven't measured it, but recharges are needed far more frequently than our light usage would suggest.That said, it could be the nature of BT headsets in general. I don't have a comparison point, so YMMV.
