VOYAGER FOCUS 2 We couldn't build a wall around you to block out background noise, so we did the next best thing: created a "focus zone" with the new Voyager Focus 2 headset. All you hear is your call with three levels of hybrid active noise canceling (ANC). All they hear is you with our pro-grade microphones using Poly Acoustic Fence technology. And while you're thinking about your call, it's thinking for you, alerting you so you never again have to say, "Oops, I forgot I'm on mute." Heck, just put on the headset and it automatically answers the call for you. It's all the Poly next-level engineering you expect with the wear-it-all-day comfort you need. ; Three levels of Advanced Digital Hybrid Active Noise Canceling (ANC). ; Advanced multiple microphone noise canceling with Acoustic Fence technology in a discreet boom. ; Stereo sound for calls and media/music. ; Dynamic Mute Alert senses and tells you when talking while muted.
