Poly CS520/520-XD/WH350-XD Headset 900 MHz-US | Wireless UC

Support productive conversations without anchoring users to their desks. The Poly CS520/520-XD/WH350-XD headset is built for office voice workflows where wireless freedom and consistent call handling matter. Its 900 MHz wireless operation positions it for business environments that need a dedicated headset solution rather than a consumer accessory. This model is well suited to teams that spend much of the day on calls and need a headset that supports movement between tasks while keeping communication clear and controlled. In practice, that means less friction for reception, customer service, and administrative roles that depend on fast response times and uninterrupted voice access. Poly’s enterprise audio heritage gives this headset added value in deployments where standardization matters. Buyers often choose this class of headset when they need a more durable, business-oriented option than entry-level wireless models can provide. The result is a headset that helps preserve focus, reduce desk clutter, and support a more efficient calling workflow across the office.
