Plantronics CS540 DECT Headset 21g 350ft Range Noise Cancel Mic

Description

Product Overview

The Plantronics CS540 is a premium DECT 6.0 wireless headset engineered for professionals who demand comfort, reliability, and crystal‑clear audio. Weighing only 21 g, it is one of the lightest commercial headsets on the market, reducing fatigue during long shifts. DECT 6.0 technology provides a dedicated 2.4 GHz band, delivering interference‑free communication up to 350 ft (100 m) from the base. The adaptive power system automatically adjusts output to maintain optimal range and battery life.

Usage

Designed for open‑plan offices, call centers, and remote workstations, the CS540 connects to most corded desk phones via an RJ9 cable—no software required. Its three wearing styles—over‑the‑ear earloop with interchangeable gels, monaural headband, or optional behind‑the‑neck band—let users choose the most comfortable fit for their workflow. The headset excels in noisy environments, making it ideal for supervisors, trainers, and agents handling high‑volume calls.
