Voyager Focus UC wireless headset

The Plantronics Voyager Focus UC 211709-101 is a stereo headset built for professionals who switch between PC and smartphone throughout the day. It connects through a 2.4 GHz ISM wireless link and includes active noise cancellation to reduce background distraction. Smart sensors automatically answer calls when the headset is put on and mute when removed.

Suits unified communications users.

This model suits workers who need seamless movement between laptops, mobile phones and Bluetooth-enabled desk phones. Precision-tuned triple microphones with enhanced DSP suppress noise on both sides of the call. Buyers who require a purely wired connection or a DECT-based system should consider other options.

The 825 USB adapter creates the dedicated 2.4 GHz wireless channel for the headset and also presents a standard USB audio interface to the operating system.
