Poly Blackwire 3210 Mono Headset, Black

The Poly Blackwire 3210 is a wired, monaural headset intended for professional use in office and call center environments. Its on-ear construction allows for situational awareness, while the lightweight yet durable metal headband provides a stable fit. The audio profile is optimized for voice clarity, utilizing a dynamic equalizer that automatically adjusts sound settings for speech or multimedia playback. It connects directly to a computer via an integrated USB-A cable for a reliable, plug-and-play setup.

This headset integrates a boom microphone with noise-canceling technology to isolate the user's voice from ambient background sound. Digital Signal Processing (DSP) is used to further enhance audio quality for both the listener and the speaker. Convenient in-line controls provide quick access to volume adjustment and microphone muting. For portability, the ear cushion folds flat, and the overall lightweight design of 87 grams supports extended use without significant fatigue.
