Give users a headset that fits the way modern desktops are built. The Cisco 321 Wired Single Carbon Black connects through USB-C, making it a clean match for laptops, docks, and workstations that have moved beyond legacy audio ports. For teams standardizing on Microsoft Teams, the Teams-qualified designation helps simplify selection for procurement and IT. The single-ear design is a practical choice for office roles that require awareness of the room while staying on calls. It supports a more open workspace than dual-ear models, which can matter for reception, administrative, and hybrid collaboration settings. The carbon black finish keeps the headset understated and professional across enterprise environments. Because it is wired, this headset avoids battery charging, wireless pairing, and radio management. That reduces support friction and keeps deployment predictable across large user groups. For organizations replacing mixed legacy headsets with a USB-C option that aligns with current endpoints and collaboration platforms, this model offers a straightforward, premium fit.
