Keep voice communications consistent across laptops, desktops, and mixed-device environments with a wired headset designed for practical enterprise use. The Poly Blackwire 3220 Stereo USB-C Headset + USB-C/A Adapter gives IT teams a simple way to standardize audio access without adding battery management, pairing steps, or wireless interference to the support load. Built for users who spend the day in calls, the stereo design helps separate conversation from ambient office noise, while the included USB-C/A adapter broadens compatibility across modern and legacy endpoints. That matters in environments where procurement wants one headset model that can cover new USB-C systems and existing USB-A fleets without creating multiple SKUs. As a bulk-packaged headset, it fits deployment models where consistency matters more than consumer-style extras. The wired connection supports predictable performance, and the Blackwire line is a familiar choice for organizations that want a clear path from purchase to rollout. For teams that value dependable audio, straightforward connectivity, and lower support overhead, this model delivers the essentials with enterprise discipline.
