I have been with Sprint for more than 10 years and since upgrading my old faithful Motorola Star Tac phone to a Samsung A900 a few months ago I have also been looking for a bluetooth headset. I have a unique requirement though, it needs to work with a full face motorcycle helmet. My commute to work is an hour each way and there are times when I need to communicate with the office on the way in or at least be accessible if they need me. That is kind of hard to do on a motorcycle.
I have heard a lot of good things about the Cardo Wireless Scala Rider and am hoping the wifey will get one for me for my birthday in November

They also sell traditional bluetooth headsets.

3. Super-slim speaker fits any helmet and adjusts volume automatically
4. Large, easy-to-reach control button
5. Volume control buttons
