Review:
Unlike any other Bluetooth headsets, the Plantronics Voyager 510 USB Bluetooth headset is the first to simultaneously support both VoIP softphones on your PC and your Bluetooth mobile phone using their exclusive Multipoint Technology. Weighing just 5.6 ounces and measuring 4.0 x 2.5 x 0.8 inches, the Plantronic Voyager 510 headset is pretty lightweight on your ear.

The Voyager 510 USB includes a plug and play Bluetooth USB adapter that works without the need for any software drivers. Very usefull when your notebook or desktop doesn't have a built-in bluetooth module already.

If you install the PerSonoCall application, you can answer/hang-up remotely to your PC. Supports Skype and other leading VOIP softwares in a breeze.

The Voyager 510 headset features a noise-canceling microphone for clearer conversations and the mic boom swivels to position on either ear. It also supports adaptive frequency hopping (AFH) which helps avoiding interference from WiFi networks.
