Poly Blackwire C3215 USB-C Monaural Headset

A simple, durable corded headset for one-ear awareness: the Blackwire C3215 connects over USB-C for PC calls and drops to a 3.5 mm plug for phones and tablets, with inline controls for answer/end, volume, and mute. The noise-canceling boom mic keeps calls clear, and the 28 mm driver handles media as comfortably as meetings.

This is the TAA-compliant bulk-pack variant (8M3X9A6) and includes the travel case — an easy fleet buy for offices standardizing on USB-C.
