Plantronics CS540 Wireless Headset (84693-01)

The Plantronics CS540 Wireless Headset is a lightweight, professional‑grade DECT headset designed for mobility, comfort, and crystal‑clear communication. Ideal for customer service teams, administrative staff, receptionists, and call‑intensive office environments, the CS540 delivers premium wideband audio, secure wireless performance, and flexible wearing styles to suit individual preferences.

With a wireless range of up to 350 feet and up to 7 hours of talk time, the CS540 ensures reliable performance throughout the workday. Its convertible design allows users to switch between over‑the‑ear, over‑the‑head, or optional behind‑the‑neck wearing styles, making it one of the most versatile headsets in its class.

DECT wireless technology eliminates interference from Wi‑Fi networks while providing superior audio quality and secure communication. The noise‑canceling microphone and enhanced wideband audio deliver clear conversations even in busy office environments. One‑touch call controls allow users to answer, end, mute, and adjust volume directly from the headset.

The CS540 supports remote call control when paired with an HL10 Handset Lifter or an Electronic Hook Switch (EHS) cable, enabling users to answer and end calls away from their desk. Its smart power management system optimizes range and battery life, and new headsets can subscribe to the base simply by docking.
