Professional DECT Headset for Office Use

The Poly CS540 Wireless DECT Headset System Bundle delivers crystal-clear audio without Wi-Fi interference for professional environments. It offers up to 350 feet of wireless range for reliable communication across large workspaces. Weighing only 21 g, the convertible single-ear headset supports three wearing styles for all-day comfort. The bundle includes the base, headband, eartips, a Goby Labs cable, and a fiber cloth.

Upgrade from Wired or Basic Wireless Headsets

This system replaces tethered desk phones or lower-range wireless models that suffer from signal dropouts. The jump is worth it when you need DECT technology that eliminates Wi-Fi interference completely. It supports conferencing with up to three additional headsets for collaborative calls. Simple docking allows new headsets to be connected effortlessly without complex pairing procedures.

Check Desk Phone Compatibility and Power

Verify your desk phone has a compatible headset port or handset lifter for electronic hookswitch control. Ensure a power outlet is available near the base station for the AC adapter. The replaceable battery charges in three hours and provides up to seven hours of talk time. SoundGuard technology protects against levels above 118 dBA, and Anti-startle technology smooths sudden signal spikes.
