This unit works! I had 2 Motorola bluetooth headsets and I was about to give up on bluetooth headses altogether. This one sounds good in the car for both the listener to whom I am talking to and for myself. In fact it actually sounds better than pressing the phone up to my ear. It can be loud as well which is good and bad. The good is when you have a lot of background noise, this thing can be heard. The bad, is it can be really loud!
