PLAN_C3210-USB-APoly Blackwire 3210 USB Headset
The Blackwire 3210 is the mono headset in Poly's Blackwire 3200 series — a best-in-class audio experience in a headset built for enterprise rollouts, at a price that lets you put one on every desk. The sleek design and flexible microphone boom give each wearer a customisable fit, and it sounds as good as it looks.
It is also a headset people actually want to wear, which is what makes the investment pay off. Need both ears covered? The Blackwire 3220 is the stereo sibling. If your laptops are USB-C, the Blackwire 3310 USB-A/C covers both connectors.

Frequently asked questions
Is the 3210 mono or stereo?
Mono — one speaker, one ear covered. For stereo, choose the Blackwire 3220.
Will it work with my UC or softphone client?
Yes — it connects as a standard USB audio device and works with the leading softphone and meeting apps on PC and Mac.
Does it need any software or charging?
No — plug the USB-A connector in and it is ready. Being corded, there is no battery to manage.
Why buy this over a consumer headset?
It is built for enterprise needs: an adjustable noise-cancelling boom for clear speech, durable construction and consistent USB audio across your whole fleet.
