The Poly Blackwire C3225 is a wired, on-ear headset with 3.5 mm and USB-A connections, designed for office work and video conferencing. The stereo model with a microphone provides high sound quality, comfortable wear, and broad compatibility with computers and mobile devices.

The headset was designed with the Unified Communications environment in mind. Plug and Play technology allows for quick setup without installing additional drivers. Thanks to the dual connectors – USB-A and 3.5 mm jack – the headset can be easily connected to laptops, desktop computers, and smartphones.

32 mm drivers offer clear, balanced sound with a range of 20–20,000 Hz. A 32 Ω impedance and 94 dB sensitivity ensure adequate dynamics during calls and multimedia playback. The unidirectional microphone with a frequency range of 100–10,000 Hz and a sensitivity of -38 dB enables clear communication during online meetings.

The lightweight design with a padded headband and soft ear cushions enhances comfort during long hours of use. Swivel earcups allow for a better fit, and the 2.2 m cable provides freedom of movement at your desk.
