The first bluetooth that I had tried was the HS-655+ for $129.00! at Sprint. Most people I spoke to with it complained that there was alot of background noise and I felt that I could not hear that great so, it was returned.I found this modal at 1/3 the price of the other and it works much better! (actually unbelievably) No one I spoke with knew that I was on a head set and I could hear them better then with the phone. The size is much bigger but I think it's more comfortable. LOVE IT! The best bang for the buck!
