The new IOGEAR and SRS labs collaboration delivers SRS wow HD to your Bluetooth enabled devices. They claim you'll get "beautifully crisp" audio quality and 6 hours of playback.
Using the joystick on the front of the receiver, you can control volume and change tracks. The device looks fairly small, but you run the risk of looking a little geeky having this clipped to your shirt pocket.
If you're in the market for a stereo Bluetooth headset, this is a steal at 89.95. Comes with a set of headphones, charger with euro adapter, and a few extra cables. No software required.
