Poly Blackwire C5210 USB-C Headset

The Poly 8M3W7A6#ABA is a Blackwire C5210 USB-C headset created for professionals who move through back-to-back meetings, training sessions, and focused work. It combines dependable wired connectivity with thoughtful design so you can stay engaged and productive wherever you plug in.

Long calls feel easier because the headband is cushioned and adjustable, and the soft synthetic leather ear cushion sits lightly against one ear. The mono layout keeps the other ear open, a practical choice when you need to stay aware of colleagues or household sounds while still hearing every word on the line.

A noise cancelling microphone filters out nearby chatter so your voice remains front and center. Dynamic EQ automatically fine-tunes audio for speech or media, while SoundGuard technology limits sudden spikes, helping protect your hearing during unexpected bursts of volume.

Connecting is straightforward. Use the 7.1 foot cable with its USB-C plug for laptops and Chromebooks, or detach the inline module and switch to the 3.5 millimeter jack for tablets and phones. The headset is certified for Microsoft Teams and Zoom, which means the call controls in the cord work the way you expect without extra setup.

When you head to a different desk or travel between home and office, fold the earcup flat, slide the headset into the included carrying case, and drop it in your bag. The dual connector design, durable build, and two-year limited warranty make it a solid daily companion for hybrid workers, call center agents, and students who rely on clear, reliable audio.
