The headset supports the A2DP Bluetooth profile and has an attachment that adds a second earbud. There are several buttons on the headset to control both phone functions as well as music player functions, but the best part comes in the form of the slider that serves two purposes, the first is to obviously bring the microphone closer to your mouth, but it also acts as the answer/end call function.

This tiny headset weighs in at a mere 15 grams and fits right in your ear with no hook or clip or other attachment until you add the second earbud, then you are granted an ear hook that is also the wire for the second earbud. Plantronics is claiming a 7 hour battery life with non-stop use and 200 hours on standby alone.

They were also kind enough to integrate some audio processing technology that should improve the quality of both your calls and your audio listening. This particular work of art will be launched in October for about $150 with the stereo earbud setup (still removable though), without, aka mono will be about $20 cheaper and will be called the 815.
