Poly Blackwire C3215 Monaural Headset

The Poly 8M3X9A6#ABA is a wired headset with a single-ear design that gives you clear communication without cutting you off from what is happening around you. It connects through either USB Type-C or the attached 3.5 mm plug, allowing quick moves between a laptop, phone, or tablet.

Comfort lasts all day thanks to a headband made from light metal that keeps its shape and a soft leather-wrapped cushion that rests gently on your ear. A microphone on a flexible boom rotates into the ideal spot and uses noise cancellation so teammates hear your voice, not the background. Inside the speaker, wideband audio, Digital Signal Processing, and Dynamic EQ work together to sharpen voices during calls and then enrich music or video when you take a break.

Practical details make everyday use simple. A 7.4-foot cable lets you stand, stretch, or reach for a file without unplugging. An inline module puts call answer, end, volume, and mute controls exactly where your hand expects them. When you head out, the ear cup folds flat and slides into the included travel case, protecting the headset in a backpack or carry-on.

The Blackwire C3215 fits people who run contact centers, attend long virtual meetings, study online courses, or need a reliable headset for hybrid work. It works seamlessly with devices running Windows, macOS, iOS, or Android.
