Voyager 835, Bluetooth Headset w/ Dual-Mic AudioIQ Noise CancelingIn the car, on the street or at the airport, be heard above the noise with the Plantronics Voyager 835 Bluetooth headset. Dual-mic AudioIQ noise canceling technology provides clear sound by separating and enhancing your voice to minimize distracting background sounds. Windsmart technology reduces the wind noise your callers would otherwise hear. A comfortable, contoured eartip channels sound directly into your ear, so you can focus on what’s important—your conversation. Plantronics QuickPair technology lets you easily pair your headset with your Bluetooth® phone and multipoint technology lets you stay connected with two Bluetooth® phones—like a PDA and personal phone— all from one lightweight headset.
