Mono USB-C headset for Teams calls

The Poly Blackwire 3310 is a monaural on-ear headset certified for Microsoft Teams. It targets office workers and remote professionals who need a single-ear design to stay aware of their surroundings while taking calls. The 32 Ohm impedance suits direct connection to laptops and mobile devices without extra amplification.

Wired USB-C and 3.5 mm connectivity only

The headset uses a fixed USB Type-C cable with an included USB-C to USB-A adapter for broader port compatibility. A 3.5 mm mini-phone jack provides an analogue fallback for devices without USB-C or USB-A ports. Audio and microphone signals travel over the wired link, so there is no battery to charge and no wireless pairing process to manage.

Plug-and-play setup with fit adjustments

Windows and macOS recognise the device automatically when the USB connector is inserted, and the Teams certification enables one-touch call control in the Teams client. The headband extends to fit different head sizes, and the ear-cup rotates to rest on either ear. The single cable cannot be replaced if damaged, so careful routing around desk edges helps avoid the most common failure point.

Questions about this item

Should I pick the 3310 monaural model or a stereo version from the 3300 series?

Choose the 3310 if you need to stay aware of your surroundings while on calls; its single ear-cup leaves one ear open. Pick a stereo model from the 3300 series only if you prefer both ears covered for immersive audio.

What does the 32 Ohm impedance mean when I plug the headset into my laptop?

The 32 Ohm rating makes the Blackwire 3310 easy to drive from any USB-C or 3.5 mm port, delivering clear voice volume without needing an external amplifier.

How does the USB-C connection with the included USB-C/A adapter affect compatibility?

The headset uses a wired USB-C interface and ships with a USB-C to USB-A adapter, so it works with both modern USB-C laptops and older USB-A ports while keeping plug-and-play simplicity.
