In the car, on the street or at the airport, be heard above the noise with the Plantronics Voyager 835 bluetooth earset. 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.
