BW-5210-USB-ACPoly BW-5210-USB-AC
The Blackwire 5210 is the mono model in Poly's mid-range Blackwire 5200 corded series — built for people who wear a headset for hours at a time and want more comfort and polish than an entry-level model offers. This USB-A/C version ships with both connector types covered, so it follows you from desktop to laptop without adapters.
Long stretches of concentrated call work? The binaural Blackwire C5220 covers both ears. Watching budgets, the Blackwire 3310 is the value mono alternative, and the Blackwire C5210 is this model's close relative.

Frequently asked questions
How does the 5210 differ from the cheaper 3300 series?
The 5200 series is Poly's comfort-focused corded range — an ergonomic design intended for people on calls most of the day, where the 3300 series is the value line for lighter use.
Do I need a USB-C adapter?
No — this USB-A/C variant covers both USB-A and USB-C connections out of the box.
Mono or binaural?
This 5210 is mono, best when you need to stay aware of colleagues. For immersion in noisy environments, choose the binaural C5220.
Will it work with my softphone?
Yes — it is a standard USB audio device and works with the leading UC clients on PC and Mac.
