Plantronics Blackwire 7225 USB-A Headset - Refurbished

The Poly Blackwire 7225 USB-A Stereo Headset helps office professionals block out background distractions and boost productivity during all-day audio, video, and multimedia tasks. Combining a stylish, pioneering boomless design with hi-fi stereo sound and on-demand active noise cancellation (ANC), this corded headset delivers a professional audio experience.

Built with USB-A connectivity and advanced digital signal processing (DSP), the Blackwire 7225 ensures crystal-clear communication and a polished look for modern workspaces.

Advanced Performance and Professional Flexibility

Engineered for open office environments, the Poly Blackwire 7225 leverages four omni-directional microphones and advanced digital signal processing (DSP) to separate ambient noise from your natural voice. The inclusion of an OpenMic feature allows users to easily hear their surroundings when needed without removing the headset. Furthermore, dynamic voice alerts notify users of status changes such as mute on, mute off, volume limits, and noise cancellation modes, ensuring seamless call management throughout the working day.

Comprehensive Connectivity and Audio Excellence

Designed to handle both high-concentration tasks and multimedia streaming, the headset outputs 24-bit audio at up to a 96 kHz sample rate through robust 32 mm speakers. Dynamic EQ automatically optimises sound profiles for voice telephony or music playback. SoundGuard DIGITAL technology protects hearing against sound levels exceeding 118 dBA, incorporates G616 anti-startle protection during calls, and utilises time-weighted averages to prevent daily noise exposure from exceeding 85 dBA.

Network Reliability and Software Management

The headset supports seamless enterprise deployment and device management through Plantronics Hub for Windows/Mac and Plantronics Manager Pro. IT administrators can centrally monitor inventory, push firmware updates, and configure security settings across organisational rollouts. The plug-and-play wired interface ensures instant connectivity without complicated driver installations.
