Poly Blackwire 3320 Headset, Black

The Poly Blackwire 3320 is a wired, on-ear stereo headset intended for professional communication in office or call center settings. It is equipped with 32 mm drivers that cover a frequency response range of 20 Hz to 20,000 Hz. For voice transmission, the headset utilizes a boom microphone with noise-canceling technology designed to isolate the user's voice from ambient background sound. The on-ear design and 131-gram weight are structured for sustained use throughout a workday.

This headset connects via a native USB-C plug, and an included USB-A adapter provides compatibility with a wider range of devices, including PCs and Macs. Audio is refined using Digital Signal Processing (DSP) to enhance clarity for calls and media. An in-line controller is integrated into the 2.18-meter cable, providing physical buttons for volume adjustment, microphone muting, and call management. This allows for direct control without reliance on software interfaces.
