This device looks too good to be true. So small it just sticks to your ear, with no wires to deal with! this was my first Bluetooth headset so I can't compare it to others, but it seems that when they make a headset this small, the mic is so far from your mouth that it has to be very sensitive to pick up your voice-- that means it picks up all the other noise as well! It is unusable in a moving car at freeway speed. It has a little analog static and noise that is annoying. My advice, don't buy a phone like the RAZR V3 planning to use a bluetooth headset until you have talked TO someone calling you from one! Side note, I had to buy an extended (2x thickness of the OEM battery) so that I could use a bluetooth device for more than an hour.
