Poly Blackwire 3320 Headset, Black

The Poly Blackwire 3320 is a wired, on-ear stereo headset engineered for professional communication. It connects directly to compatible devices via a USB-C cable, providing a stable plug-and-play interface for calls and media. Audio is reproduced by 32 mm dynamic drivers with a standard frequency response of 20 Hz to 20,000 Hz. The closed-back, on-ear design offers passive sound isolation. For user comfort during extended use, the headset incorporates a padded, adjustable headband and soft foam ear cushions, with an overall weight of 130 grams.

This headset features a boom microphone equipped with noise-canceling technology to minimize ambient sound and improve vocal clarity during calls. The microphone's frequency response is specified at 100 Hz to 10,000 Hz, focusing on the human voice spectrum. Integrated Digital Signal Processing (DSP) further refines audio for clear communication. An in-line control unit is located on the 2.0-meter cable, providing tactile buttons for managing volume, muting the microphone, and handling calls without interacting with the host device's software.
