Flat out this thing is the loudest and clearest bluetooth headset I've ever used. It has two detractors to it and that is why I rated it at four stars instead of five.One the thing is huge and a little goofy looking on your head but then again aren't all headsets?Two the mouth piece is so sensitive that people will hear what you are doing and that can be a bit distracting.All and all though this is a great product. I would Recommend it.
