Motorola Miniblue Bluetooth Headset H9 - Motorola
This is not yet available, but I'm very interested in getting one once it is. I currently have a Motorola H500 that I'm happy with. However, the H9 is supposed to have superior noise canceling abilities. I also like how small it is and that it sits inside your year (I'm guessing that might help the quality and volume of the sound you hear).
