Plantronics Discovery 640 Bluetooth Headset Switches Back & Forth Between Two Phones

Plantronics is calling their Discovery 640 bluetooth headset the “ultimate bluetooth headset”. On the surface the Plantronics Discovery 640 looks like a pretty ordinary bluetooth headset, but it might just be the ultimate bluetooth headset after all since it’s capable of connecting to and switching back and forth between two bluetooth phones. Aside from those special powers, it weighs only 1/2 an ounce, and it has a range of up to 33 feet. Plantronics Discovery 640 bluetooth headset retails for $74.99 at Amazon. And in case your interested in this because you’re one of those folks who carry around two cell phones, Mobile Tech Review reviewed the Discovery 640 and gave it a 4 out of 5 star rating.
