Briefly and to the point - do not buy this item. I am returning it. Much worse than 3 different blue tooth ear pieces I own. Bought for my girlfriend who finds earpieces uncomfortable. After 3 days of using this on her 2 hour round trip commute and getting constant complaints about the quality of the conversations she is back using a $29 earpiece device. We tried many different positions for the device in her car (new, quite Acura) with both of us being the talker and driver and the only even remotely acceptable voice quality was when we held it about 4-6 inches directly in front of our mouth. Incoming audio quality was very good but outgoing quality was extremely distorted.
