I have a Road King and would love to have it just so I can listen to music on my iPhone. That way I dont have to install a radio. Bluetooth (a wireless option) is perfect for this. I would love to hear if anyone has been able to use a headset under a helmet. The BlueAnt Interphone looks great but is a little expensive (about $139) wherever I've looked. Lots of these headsets are $50 or less. Thanks for the help.
