PLAN_C3225Poly Blackwire C3225 Binaural USB Headset
The Blackwire C3225 is the binaural model in Poly's Blackwire 3200 series: a corded USB headset that covers both ears, making it the natural pick for open-plan offices and busy home setups where users need to block out what is going on around them and concentrate on the call.
It is a dependable standard-issue headset for softphone users — nothing to charge, nothing to pair. The same model is also listed here as a USB-A specific variant, and if you want the lighter single-sided approach the Blackwire C3215 USB-C is its stablemate.
Key features

Frequently asked questions
What does binaural mean?
Binaural means the headset has a speaker over each ear. It gives better focus and call clarity in noisy environments than a single-ear (monaural) design, which instead keeps one ear free for the room.
Does it work with my softphone?
It connects as a standard USB audio device, so mainstream softphone platforms will pick it up for calls. Tell us your platform if you would like us to double-check before a larger order.
What is in the box?
The headset and a quick start guide.
