Best bluetooth earpiece I've come across so far. Lightweight, comfortable for several hours a day, and good to excellent reception. Ocasionally someone tells me I sound like I'm "talking on a cellphone"...meaning not perfectly clear like a land line. So who cares...you get hands-free! Battery life is good...keeps going all day without needing a charge till the evening. It comes with several adapters for charging options. Also 3 sizes of earbuds. As I use a Blackberry 8700, this device is perfect.
