I always check Consumer Reports for ratings before purchasing goods. They rated this bluetooth as a "Best Buy" and it was rated excellent for sound quality. I figured that to be the most important feature in a bluetooth headset, so I ordered one some months ago from a seller on Ebay (for the same price as the 2 I bought on Amazon). I LOVE mine...so, for Christmas I ordered one for my husband and one for his daughter--ad they both LOVE them, too. If I have any 'criticism' whatsoever, it is that the headset is easily 'bumped off' the ear by a coat collar, etc., but its not like you wouldn't notice it ;-). The sound quality is excellent--so much better than trying to hold a rigid cell phone up to your ear to try to hear someone talking. My husband has diminished hearing and this has been wonderful for him, as he can adjust the volume accordingly. In short, we think these are great! Not only that, the price on Amazon is less than 50% of the manufacturer's website price. It is an excellent buy in my opinion.
