The sound quality is awful. Sounds like a $5 pair of headphones. Works fine inside, but go outside and it won't pick up a signal from a blackberry on your belt. It will however work, if you hold the phone within a foot (12 inches) of your head. Totally defeats the purpose of a wireless device. I have a friend that uses them with the Iphone, and he claims they work fine. Maybe I got a lemon? Or maybe Motorola needs to step up and give it a more powerful receiver and battery.Wait for the next generation to come out. At least wires work.cl
