View RequirementsProduct Overview
With DECT 6.0 technology, the CS540 provides interference-free wireless communication with up to 350 feet of range from the base station. The advanced wideband audio using CAT-iq technology delivers high-definition voice quality, making speech sound clearer and more natural. Enhanced Digital Signal Processing (DSP) further improves audio clarity for professional conversations.
The CS540 features a convertible design with three wearing options: over-the-ear with earloop, over-the-head with headband, or behind-the-head with optional neckband. One-touch controls for call answer/end, volume, and mute are at your fingertips, and teams can conference up to four headsets on a single base for enhanced collaboration. For remote call answer/end capabilities, pair with the optional HL10 Handset Lifter or Electronic Hook Switch (EHS) cable.
