The Plantronics Voyager 855 Bluetooth Headset is the only BT headset I know of that features a detachable second earbud that is used to convert the mono sound headset into a stereo headset. This comes in handy when you want to listen to music and podcasts on your cell phone wirelessly. The second removable earbud also helps to cancel out background noise during phone calls in noisy places.

The Voyager 855 is designed for lengthy work days or long commutes. Its rechargeable lithium polymer battery will give you up to seven hours of talk time and 160 hours of standby time from a single charge. An easy-to-read indicator lets you quickly check your battery level. For extreme convenience, the earpiece features one-touch buttons that put call and music controls -- such volume, mic mute, last-number redial, voice-activated dialing, music pause and play, and track back and forward -- conveniently at your fingertips.
