Poly CS540A DECT Headset

The Poly CS540 DECT Headset is a premium convertible headset built for office workers who need mobility and all-day comfort in their conversations.

Simplify desk phone management with headset audio controls and adding either the HL10 Handset Lifter or Electronic Hook Switch Cable (EHC) for remote call capabilities.

Extended range and talk time

The adaptive power system optimizes for range and talks time by automatically downshifting to low power when the headset is close to the base — saving battery life and maintaining maximum density.

SoundGuard technology

SoundGuard acoustic limiting technology protects against Acoustic Shock by limiting sounds to below 118dBA ensuring listening comfort and protection against audio spikes.

Superior audio quality

Your choice of narrowband audio to extend talk time or advanced wideband audio for high — definition voice quality. Enhanced Digital Signal Processing (DSP) provides more natural sound, delivering clear audio the way it’s intended to be heard.

Maximum protection

The Poly CS540 DECT Headset includes DECT™ technology that provides better audio quality and eliminates interference from Wi-Fi networks while calls stay safe and secure.
