Plantronics Voyager Focus UC Bluetooth Headset

Plantronics has also designed the headset to have intuitive control over all of its functions. Integrated intelligent sensors turn off the music when a call is received and the mute function is easily toggled via a button on the headset. A light on the USB key will let you know if you are in silent mode or not. An LED light on the outside of the headset will alert your colleagues if you are taking a call. If you just don't want to talk to them, this can be activated manually!
This headset uses a Bluetooth USB dongle to connect to PCs, but can also connect wirelessly to tablets and smartphones. You will always be able to keep your hands free during a call or listening to music whilst working. The 45-meter range gives you the freedom to move around and you also have up to 12 hours of talk time off of a single charge.
