The Plantronics CS540 XD wireless headset features 900 MHz technology, which allows a greater density of headsets within one area. More voice channels can be deployed in one spot without them interfering with each other. Wear and use the headset up to 350 feet away from the base, with up to six hours of talk time in the included battery.

Digital signal processing cleans up incoming audio through the single earpiece. Choose wideband or narrowband performance, allowing you to conserve battery life. The microphone on the Plantronics CS540 XD includes noise cancellation technology to block background noise from reaching your caller. A convertible design allows you to change the form of this lightweight headset into one that matches your preferred style.
