Power in the base

A sleek charging base is included with the CS500 Series. An adaptive power system optimizes for range and talk time by automatically downshifting to low power when the headset is close to the base to save battery life.
Outstanding audio quality

Voice-dedicated DECT™ technology provides better audio and eliminates interference from Wi-Fi networks while advanced wideband audio provides high definition voice quality. Your choice of narrow or wideband professional grade audio quality — choose narrowband to extend talk time or wideband mode to enable clearer conversations. An extended boom and noise-canceling microphone filter out background noise, so listeners can hear conversations clearly and enhanced Digital Signal Processing (DSP) provides more natural sound, delivering clear audio the way it’s intended to be heard.
DECT security certified

Advanced Dect wireless security. Using the latest standards in DECT wireless security, CS500 series headsets keep conversations safe and secure. With eight discreet security measures, including a 64-bit encryption, confidential information remains private.
