Poly Blackwire 3320 Headset, Black

The Poly Blackwire 3320 is a wired, on-ear stereo headset designed for professional environments. It connects directly to devices via a USB-C cable, and an included USB-A adapter ensures broad compatibility with various computers. The headset is equipped with 32 mm dynamic drivers that deliver a standard frequency response of 20 Hz to 20 kHz, suitable for voice calls and general media use. Its lightweight construction, weighing 130 grams, is intended for sustained comfort throughout a full workday.

For communication, the headset incorporates a flexible boom microphone with noise-canceling technology to reduce the intrusion of ambient background sounds. Audio quality is further refined by Digital Signal Processing (DSP) for clearer conversations. An in-line controller is integrated into the cable, providing direct access to call answer/end functions, volume adjustment, and a microphone mute button.
