Poly Blackwire 3310 Mono USB-C Headset (Microsoft Teams Certified)

The Poly 8X216AA is a headset built for professionals who jump from video meetings to phone calls and back again without missing a beat. Part of the Blackwire 3310 family, it uses a single ear design so you can stay aware of what is happening around you while still hearing every word from your computer or mobile device. A padded headband and a soft ear cushion make it comfortable enough for day-long use, whether you spend your hours at a desk, in a shared office, or working from a kitchen table.

Voice clarity comes from a flexible boom microphone that you can position exactly where it needs to be, helping teammates or customers hear you the first time. Inline controls sit right on the cable, giving you instant reach over call answer, volume, mute, and even media playback when you are catching up on training videos between meetings.

Connection options are straightforward. Plug the USB-C cable into a modern laptop, snap on the included USB-A adapter for older desktops, or switch to the 3.5 millimeter jack when you take a call on a tablet or phone. Because the headset is certified for Microsoft Teams, a dedicated button puts you into a meeting or brings up notifications without hunting through menus.

The wired design delivers steady audio with no batteries to charge, and the 7.15 foot cable gives you room to stand, stretch, or reach for a notebook while you talk. When the day is done, the headset folds flat and slips into a bag or drawer, ready for the next shift or trip across town.
