HP Poly Blackwire C3210 Mono USB-A Wired Headset

Keep one ear available for nearby colleagues, visitors, and alerts while handling computer-based calls through a dedicated wired USB Type-A connection. The HP Poly Blackwire C3210 combines a single supra-aural earpiece with an over-the-head wearing style, making it suited to users who alternate between voice conversations and in-person communication. Its black finish keeps the headset appropriate for standard office, contact-center, and support-desk workstations. A boom microphone places voice pickup close to the speaker, while noise-cancelling microphone technology helps reduce surrounding sound during calls. The headset supports audio from 20 Hz to 20 kHz for voice, conferencing, training material, and general PC audio. Wired connectivity avoids pairing steps and battery charging, which is useful where a headset remains assigned to a fixed desk or shared computer. Within the Blackwire 3200 family, this configuration is defined by its monaural listening design and USB Type-A host interface rather than a stereo layout or alternate connector. Part number 209744-104 suits environments where a single-ear headset is preferred for maintaining awareness of the immediate workspace. The supra-aural cushion rests on the ear instead of enclosing it, supporting a lighter, more open wearing position for extended call handling.
