The Plantronics Voyager Legend has three precisely tuned microphones and enhanced DSP that optimize your voice and minimize noise caused by wind, movement, and background sounds. Industry-first Smart Sensor technology intuitively directs calls to your phone or headset and allows you to automatically answer by placing the headset on your ear. The headset also takes voice commands such as “pair”, “answer” or “ignore” to keep you in control of your technology.
