Poly Blackwire 5210 Mono USB-C Headset

The Poly 8X230AA is a mono headset that gives professionals clear voice communication and day-long comfort, whether they work from a home office, an open plan floor, or a shared classroom. It pairs a single ear cup with a headband that is lightweight and adjustable, so you stay aware of your surroundings while still hearing every word. A soft leatherette cushion rests gently against the ear, keeping fatigue to a minimum during back-to-back meetings or extended training sessions.

Your callers will hear you, not the chatter around you. The boom houses a noise canceling microphone that filters out nearby conversations and office equipment, and it rotates 280 degrees, allowing you to position it on either side for the most natural fit. Passive noise isolation in the ear cup reduces distractions on your end as well, helping you stay focused on the task at hand.

Versatile connectivity means less fumbling and more productivity. Plug the headset directly into a USB-C port on a laptop, Chromebook, or modern tablet, or detach the cable to reveal a 3.5 mm jack for phones or older devices. With the same headset you can join a video conference, listen to training videos on a tablet, and answer a mobile call without changing gear.

Everyday controls sit right on the cable. Answer or end a call, adjust the volume, or mute the mic with a quick press, instead of diving into on-screen menus. When it is time to move, the ear cup folds flat so the headset slips easily into a bag or desk drawer.

From its durable build to its 20 Hz to 20 kHz frequency response, the Blackwire 5210 line is trusted in corporate deployments and remote setups alike. If you need a reliable tool that keeps you heard and comfortable through an entire workday, this headset fits naturally into your workflow.
