Plantronics intros Discovery 655 Bluetooth headset {Engadget Mobile}

Sep 5th 2006 1:42PM I recently got the Treo 700p and I am torn between the Plantronics Discovery 655, and the Palm Ultralightweight Headset (aka. the Plantronics 645). Both seem like great headsets with form factor being the only or the main distinguising factor? They both are reviewed very highly, any thoughts on which one operates/sounds/feels better?
