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.
