Wired USB-A Monaural Headset

The Plantronics Blackwire 3210 connects to a PC or Mac through a single USB-A port and covers one ear for call clarity. It targets users moving to desktop telephony who need a simple plug-in device for webinars and conference calls. A noise-cancelling boom microphone and wideband audio aim to keep speech natural during long sessions.

Fit and Deployment

No software installation is required because the headset is not app-enabled and draws power directly from the host computer. The over-the-head metal headband adjusts for a custom fit while the leatherette cushion rests over one ear. Leaving the other ear open lets the wearer stay aware of office surroundings without removing the headset.

Audio Scope and Limits

The drivers reproduce frequencies from 20 Hz to 20 kHz while the microphone captures between 100 Hz and 10 kHz. SoundGuard acoustic limiting caps output at 118 dBA to protect hearing during sudden volume spikes. The mono design means stereo multimedia playback is not supported, and the wired USB-A connection prevents use with devices that only offer 3.5 mm or wireless interfaces.
