Plantronics CS540A Wireless Mono Headset with Office Base, Black

The Plantronics CS540A is a DECT wireless headset designed for professional use in office and call center environments. It operates on a dedicated DECT frequency, which provides a stable wireless connection up to 120 meters from the base station. The mono headset weighs 21 grams, and its convertible construction supports three wearing styles: over-the-ear, over-the-head, and behind-the-neck. This design provides user-selectable options for comfort during extended use.

For voice communication, the headset is equipped with a noise-canceling boom microphone to reduce the transmission of ambient background sound. The audio output benefits from Digital Signal Processing (DSP) to refine sound quality. Call management functions such as answer, end, mute, and volume adjustment are accessible via controls located directly on the earpiece. The integrated battery provides up to 7 hours of talk time on a full charge, which accommodates a standard workday.
