Pushing the limits of headset technology, the Voyager PRO is the most advanced noise-canceling Bluetooth headset available. Two noise-canceling mics on a boom, AudioIQ² technology with its adaptive 20-band equalizer, and three layers of WindSmart technology ensure that you hear every word and that your voice is heard clearly despite the noise around you. This extremely comfortable, behind-the-ear headset is further proof of Plantronics' 40-plus years of commitment to headset engineering excellence.
