Mono headset for Teams-certified calls

The Poly Blackwire 3310 is a mono on-ear headset built for professionals who spend long hours on Microsoft Teams calls. Its single-ear design keeps one ear open to the surrounding office while the USB-A connection provides instant plug-and-play compatibility with Windows PCs. The 32 Ohm impedance and 20 Hz to 20 kHz frequency response deliver clear voice reproduction for conference sessions.

USB-A and 3.5 mm dual connectivity decides fit

The headset terminates in a USB Type-A plug and includes a 3.5 mm mini-phone connector, giving two wired options for different devices. This dual interface is the specification that determines whether the 3310 matches your workstation or mobile phone port. The 7.10 ft cable length provides enough reach for desk setups without excess slack.

Inline controls replace software setup

An integrated inline controller handles call answer, end, mute and volume adjustment directly on the cable. No driver installation or companion application is required to access these functions. The omnidirectional boom microphone pivots out of the way when not in use, and the lightweight frame rests on a single ear cup for all-day wear.

Questions about this item

What does the 20 Hz to 20 kHz range mean for call quality?

It covers the full range of human hearing so voices sound natural and background noise is reproduced accurately during calls.

What does the USB Type A and 3.5 mm combo connection limit?

It limits use to devices with a USB-A port or a 3.5 mm jack; newer USB-C only laptops need an adapter.

How much space does the 7.10 ft cable need on a desk?

The 7.10 ft cable gives ample reach from a desktop PC or dock without pulling tight across the workspace.
