The POLY CS540A is a professional wireless headset for everyday office calls. It combines an ultra-light design with advanced DSP processing for natural voice and a noise-canceling microphone for clear intelligibility even in noisy environments. DECT technology ensures stable range and secure communication without Wi‑Fi interference.
The headset supports three wearing styles (over-the-ear, headband, behind-the-head) and easy call control directly on the headset. With the optional HL10 lifter or EHC cable, you get remote call answer/end. Adaptive power conserves the battery and extends talk time, while SoundGuard protects hearing against acoustic shocks.
For team collaboration, you can pair up to 4 headsets to a single base, so colleagues can easily join a call or training. A range of up to 120 m gives you the freedom to move around the office without losing audio quality.
