Poly Blackwire 3310 Monaural USB-C/A Headset

The Blackwire 3310 is the mono model in Poly's Blackwire 3300 corded series — a sensible, budget-friendly choice for hybrid desks, reception positions and anyone who needs one ear on the call and one on the room. This USB-A/C version covers both connector types, so it moves happily between desktop PCs and modern laptops.

Spend most of the day in back-to-back calls? The duo Blackwire 3320 USB-A/C covers both ears; if you only ever connect to USB-A, the Blackwire 3320 USB-A keeps things simple. For a plusher mono option see the Blackwire 5210.
