This earpiece is an okay product. I wouldn't say great though. It has definetely come in very handy and served it's purpose. However, it said that it had a noise cancelling microphone and I'm not sure if maybe I misunderstood what that meant. I assumed that it would block out sounds other than your voice to the person you were talking to but that is not the case. People have complained about hearing my air conditioning and my music. The music I could understand I suppose, but not the a/c. The other day I had another problem with it when it was plugged in to my cellphone but I couldn't hear anything but the person on the other end could hear me, so I had to unplug it and plug it back in again. Overall, I do like the earpiece but I wouldn't give it an exceptional rating.
