Poly BlackWire 3320 USB-C Headset

The Poly 8M3U9AA#ABA is a Blackwire 3320 USB C headset that delivers clear, dependable audio for calls, video meetings, and everyday listening. With a single USB C plug, it pairs instantly with modern laptops and tablets, making it a simple addition to office workstations, remote setups, and shared hot-desking environments.

Comfort matters during long workdays, so Poly shaped the headband with soft padding and fitted each ear with a cushion that uses plush leatherette. The result is a headset that feels light on the head and gentle against the ears, even when you wear it for hours.

Sound clarity comes from Poly’s noise-canceling microphone and built-in digital signal processing. Background chatter fades, and your voice sounds natural on the other end of the line. A boom arm that rotates through 280 degrees lets you position the mic on either side, then move it out of the way when you step away from the desk or switch to music.

The rugged wired design stands up to daily handling and travel. A 7.1 ft cable gives you room to move during presentations, and the headset remains powered without batteries or charging breaks. Because it is TAA compliant and certified for leading platforms such as Microsoft Teams and Zoom, IT administrators can deploy it across government offices, enterprise fleets, and call centers with confidence.
