Plantronics Discovery 650

Plantronics Discovery 650 ... at a time a PDA and a mobile phone, for example. The Discovery 650 is ultra lightweight, weighing just 9 grams, but it manages to incorporate the legendary Plantronics sound quality, as well as a host of useful features ranging from a headset pocket with call alert and auto answer, to a AAA battery charger that extends standby time up to 170 hours.
