Poly couldn't build a wall around you to block out background noise, so Poly 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 the pro-grade microphones using Poly Acoustic Fence technology. It's all the Poly next-level engineering you expect with the wear-it-all-day comfort you need. Connect to a computer with the included BT700 USB-A adapter and to a mobile via Bluetooth v5.1.
