Poly Blackwire 3325 Headset, Black

The Poly Blackwire 3325 is a binaural, on-ear headset designed for professional communication environments. It offers versatile connectivity, featuring a primary USB-A interface for computers and an additional 3.5 mm connector for compatibility with mobile devices. Audio is produced by 32 mm dynamic drivers that cover a frequency response range of 20 Hz to 20,000 Hz. With an impedance of 32 Ω and a sensitivity of 94 dB, the headset is engineered for standard office equipment and unified communications platforms.

For voice clarity during calls, the headset incorporates a flexible boom arm with a noise-canceling microphone. This microphone is designed to isolate the user's voice from ambient noise and operates within a frequency range of 100 Hz to 10,000 Hz. Convenient in-line controls are integrated into the cable, providing direct management of volume, microphone mute, and call handling functions. The audio output is further refined with Digital Signal Processing (DSP) to optimize sound for both calls and music.
