Poly Blackwire C5210 USB-C Headset

The Poly 805H4A6 is a versatile USB-C headset designed for professionals who spend much of the day on calls or virtual meetings. It offers a single on-ear speaker that keeps one ear open to the room, so you can stay engaged with colleagues or stay alert to your surroundings while still hearing every word from the other end of the line.

Comfort is built in from the first call to the last. A headband made of metal feels light yet durable and includes a soft cushion that rests gently on your head. The ear pad uses memory foam covered in smooth leatherette, so it molds to your ear and stays comfortable through long sessions.

Calls sound clear because the headset pairs a noise-canceling microphone with passive noise-blocking ear padding. Together, they reduce distractions and let your voice come through naturally. Internal digital signal processing fine-tunes audio even further, giving conversations a balanced, lifelike tone.

Flexibility is another strong point. The headset connects by USB-C for modern laptops and tablets, and it also includes a 3.5 mm plug for phones or any device with a standard audio jack. Inline controls sit on the cable where your hand naturally lands, making it easy to answer or end a call, adjust volume, or mute yourself without hunting through software menus.

When your day takes you away from the desk, the ear cup folds flat and slips into the included carrying case. That design protects the headset in a backpack or briefcase, making it a smart choice for hybrid workers, frequent travelers, and anyone who switches between home and office.

Compatibility with leading meeting platforms means you can join sessions on Microsoft Teams, Zoom, Google Meet, and more without extra setup. Simply plug in, select the headset in your audio settings, and start talking.
