The CS540 Wireless Headset System by Plantronics sets the new benchmark in DECT (digital enhanced cordless telecommunication) wireless headsets. DECT technology delivers crystal-clear audio while avoiding interference from Wi-Fi networks. The CS540 combines sleek, modern design with a lightweight 0.74 oz (21 g) headset featuring intuitive one-touch call/answer, volume, mute, and flash controls. Enjoy up to 350 feet of hands-free mobility with a replaceable battery that charges in three hours and provides up to seven hours of use. The noise-canceling microphone minimizes background noise for superior audio quality and reduced listener fatigue. SoundGuard technology safeguards against sound levels exceeding 118 dBA, while Anti-startle technology prevents sudden audio spikes. Setup is effortless—just connect the CS540 base to any desk phone using the included interface cable. Answer calls with a button press or enable auto-answer for touchless operation. Experience HD voice quality with wideband audio and advanced DSP for natural, clear speech. Pair new headsets by docking them to the base, and connect up to three additional headsets for collaboration. Optional Electronic Hookswitch Cables or Handset Lifters enable remote call management (sold separately).
