BW-3320-USBAPoly Blackwire 3320 USB-A Stereo Headset
The Blackwire 3320 USB-A is the stereo, wired, USB-A member of Poly's Blackwire 3300 series — the straightforward choice when every machine on the floor has a spare USB-A port and you just want reliable, consistent call audio at each desk.
Rolling out to a mix of USB-A and USB-C machines? The Blackwire 3320 USB-A/C covers both connectors in one SKU. Prefer a single-ear design, look at the mono Blackwire 3310; for a comfort upgrade there is the Blackwire C5220.

Will it work with my softphone or meeting app?
Yes — it appears as a standard USB audio device and works with the leading UC clients on PC and Mac.
