This little earpiece is amazing. The sound quality is very impressive. Teh fit in the ear canal helps block out so much sound that it can actually be difficult to hear someone if you are NOT using the phone!It weighs next to nothing and the sound quality on theother end, I'm told, is as good as if I wasn't using my headset at all.Very affordable, very comfortable, great sound quality. The only downside is the batter life is short. Make sure you have your charger with you - it doesnt' take long to recharge it, but you will have to charge it more often than you expect.
