Altec-Lansing Backbeat 903 Stereo headset. $59 from newegg. I have a little trouble getting the music going from the inc to the headset, but for the most part I am incredibly happy with these. They exhibited a music cut out with my old Storm 9530 if the headphones were seperated from the device more than 4 feet. I do not get this phenomena with my inc, which says my storm bluetooth radio stunk to heck...
This headset has the exact same plug as the inc, however I'm not sure the power supply's match up voltage or otherwise...
