Stop juggling devices just to take a call! The Plantronics Voyager 510 Bluetooth Headset System with Lifter lets users switch between calls from their desk phone and Bluetooth cell phone or other Bluetooth device with the touch of a button. Thanks to its "smart" technology, the Plantronics Voyager headset knows which phone or device to connect to, and with the included handset lifter, users have the freedom to take and end calls up to 33 feet from their desk. The headset's advanced noise-canceling and WindSmart technologies ensure that calls will be heard loudly and clearly every time.
