The Plantronics CS540 wireless headphone system is the new standard in DECT headsets. This innovative accessory delivers great sound and eliminates Wi-Fi interference. The CS540 includes all the features expected from a wireless headset and is powered by a removable battery that charges in three hours and lasts up to seven hours. Key properties include a compact design with an ultra-light headset weighing 0.74 oz (21 g), an energy-saving adaptive power system that optimizes call range and time, Anti-Startle technology that detects and eliminates sudden surges in signal level, and adjustable speaker volume. Plantronics has made setup simple, as the CS540 base connects to other equipment using the included interface cable. Calls can be answered by tapping the button on the headset, or automatically by lifting the handset when the automatic answer function is enabled. Once connected, the system delivers high-definition voice quality using advanced wideband audio technology and a DSP processor that provides clear and natural speech. Noise-canceling microphones reduce background noise to improve sound quality and reduce listener fatigue. SoundGuard technology protects against noise levels above 118 dBA, while the Anti-Startle system eliminates sudden spikes in signal level, making the Plantronics CS540 comfortable and safe for extended listening.
