Summary: Pretty good, the only negative was that the people on the other end thought I sounded a little muffled. Not as good as using the actual phone, but really convenient as hell, good signal, good charge time.
Pros: Durable, Good Sound, Good Volume Control, Lightweight
Summary: I am pretty new to the blue tooth craze, but this is already the second headset that I own. I like that the whole unit doesn't hang from my ear, it is comfortable, and it works great ( not like the first one I owned, that I have since run over with my car).
Pros: Clear Signal, Good Sound, Good Volume Control, Lightweight
