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 & eliminates interference from Wi-Fi networks while advanced wideband audio provides high definition voice quality. 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.
The DECT headset: Your security checklist
Committed to security.
The first headsets to meet the enhanced security standards of the DECT Forum Security Certificate, designed to reduce the risk of eavesdropping.
Interference-free technology.
Plantronics DECT headsets provide excellent range and audio quality because DECT operates at 1.9 GHz,a dedicated part of the wireless spectrum.
Multitask on the move
Roaming capabilities of up to 350 feet from the base set enable users to work where they want, when they want, and how they want.
Stronger data stream protection.
Standard on-air key allocation creates a secure link when the headset is registered, protecting communications from man-in-the-middle attacks.
A new key every minute.
Derived cipher key procedure limits the opportunity for hacking attempts by updating the cipher key at least once every 60 seconds during the encryption process.
Invalid connection attempts neutralized.
With evaluation of peer sides behavior, suspect behavior between the headset and the base station will terminate the call to reduce the chance of security risks.
One central view
Manager Pro deploys firmware updates for Savi 700 & Savi 400 products remotely from centrally managed applications and services, making it simple.
