BW-C5210-USBCPoly Blackwire C5210 USB-C Wired Headset
The Blackwire C5210 is Poly's entry-level wired USB-C headset for desk-based calling — a straightforward, reliable choice for anyone who is on softphone or UC calls for most of the day and wants a headset that just plugs in and works.
It is a mono (single-ear) design, so you can still hear the room around you, which suits open-plan offices and hybrid desks. For a stereo version for focused calls and music, the wider Blackwire 5200 range covers that too — ask us for the matching stereo model.
Being USB-C rather than the older USB-A connector, it is a good match for modern laptops and docking stations without an adapter.
Key features
- USB-C plug-and-play no drivers, works with major UC platforms out of the box.
- Noise-cancelling microphone cuts background office noise so callers hear you clearly.
- Foldable, lightweight design comfortable for a full day of calls and easy to pack for hybrid working.
- In-line call controls answer, end and adjust volume without touching your PC.

Frequently asked questions
Is this mono or stereo?
Mono — one ear free, which suits people who need to stay aware of the room while on calls.
Will it work with my softphone?
Yes, it's a standard USB-C UC headset and is recognised by all the major softphone and UC platforms without extra drivers.
Does it work with a desk phone?
It's a USB headset built for PC/softphone use rather than a traditional desk phone handset port — for desk phone use, ask us about our RJ9 wired options.
