Poly Blackwire 3210 Monaural USB-C Headset

The Poly Blackwire 3210 is a monaural, USB-C-only wired headset from the Blackwire 3200 Series, built for enterprise desk calling. A noise-canceling omnidirectional microphone and Dynamic EQ — which optimizes voice quality on calls and automatically re-tunes for music and multimedia playback — are paired with a 28mm speaker for clear, reliable audio.

A lightweight metal headband with foam ear cushions keeps the monaural design comfortable for one-ear wear through long shifts, with simple inline controls for call answer/end/hold, redial, mute and volume. SoundGuard acoustic protection limits sound exposure to below 118 dBA, and the headset is certified to work with Skype for Business, Cisco Jabber and Avaya.
