Poly Blackwire 3325 Headset, Black/Red

The Poly Blackwire 3325 is a wired stereo headset engineered specifically for office environments, call centers, and daily communication tasks. It features a lightweight headband design paired with closed-acoustic, on-ear earcups finished in a black-and-red color scheme. Connectivity is handled through a versatile dual-interface design, allowing users to connect via a USB-C port or a standard 3.5 mm audio jack. This wired configuration ensures stable audio transmission without relying on wireless protocols or battery power.

For voice capture, the headset utilizes a boom microphone equipped with an omnidirectional pickup pattern and integrated noise-canceling technology to minimize background noise. Audio playback is supported in stereo, delivering balanced sound suitable for both conferencing applications and multimedia. Users can manage their active calls using the inline volume controls and a dedicated mute function to quickly suspend transmission. The control layout provides immediate, tactile access to these core settings during long meetings or extended shifts.
