Poly Blackwire 3215 Mono Headset, Black

The Poly Blackwire 3215 is a wired, monaural headset designed for office and call center environments. It offers flexible connectivity with both a USB-C and a 3.5 mm connector, enabling use with a wide range of computers and mobile devices. The supraaural (on-ear) form factor is built on a lightweight 96 g frame intended for extended wear. Audio is produced by 30 mm drivers that cover a frequency range of 20 Hz to 20,000 Hz, suitable for voice-centric applications.

For communication, the headset features a boom microphone with noise-canceling technology to reduce the transmission of ambient sounds. This microphone utilizes an omnidirectional pickup pattern and is complemented by Digital Signal Processing (DSP) to enhance audio clarity. An in-line control unit is integrated into the cable, providing physical buttons for volume adjustment and a microphone mute function. The headset has a closed-back acoustic design to provide a degree of passive sound isolation.
