The DECT headset now features a sleeker design, optimized performance, and the same reliable hands-free operation that has made the CS family a bestseller for nearly ten years. With the call answer/end button, as well as the volume and mute buttons, calls can be managed from up to 110 meters away from the base station. To simplify collaboration, the CS500 system also allows you to hold conferences with up to three additional headsets. Guest headsets can be registered simply by docking them to a base station. Use the system with an Electronic Hook Switch cable or a handset lifter for remote call answering/ending.

An elegant charging station is included with the CS500 series. To extend battery life, the adaptive power management optimizes range and talk time by automatically switching to low power mode when the headset is near the base station. DECT technology delivers optimized sound quality and suppresses interference from WiFi networks, while the improved wideband audio connection ensures incredible voice clarity. Choose between professional narrowband or wideband audio quality: the narrowband mode maximizes talk time, while the wideband mode enhances call quality. An extended microphone arm and the noise-canceling microphone filter out background noise, ensuring that conversation partners are clearly understood. Enhanced digital signal processing also provides a more natural sound.

The electronic hookswitch control module APS-11 (available separately) can be used with a Plantronics DECT headset to take over the automatic control of the DECT phone, eliminating the need for an HL10 lifter.
