The HP Poly CS540A DECT Wireless Headset TAA Certified US (7W073AA#ABA) was designed for contact centers that use desk phones, government settings and busy workplaces, this wireless headset is lightweight and convertible. It provides clear, interference-resistant audio with a great roaming range, usually up to a few hundred feet from the base, using secure DECT wireless technology in the 1920–1930 MHz band. Even in busy open workspaces, a noise-canceling microphone, wideband audio and acoustic protection technologies assist guarantee that both parties have natural, fatigue-free talks. Its convertible design allows users to select over-the-ear or over-the-head comfort and its TAA certification qualifies it for government and regulated deployments. The HP Poly CS540A was created as a professional DECT office headset that allows users to wander about while on calls by pairing to a desk phone via its small base station. When used in conjunction with suitable lifters or electronic hook switch (EHS) cables, the base provides functions like remote call control and connects via a regular telephone interface cable. Because the headset is incredibly light, it helps lessen pressure and neck discomfort during extended phone calls. The CS540A strikes a compromise between long conversation times and high-density deployments in multi-user settings with an adaptive power system that maximizes transmission strength dependent on distance from the base. For call-intensive jobs, SoundGuard-style acoustic protection helps prevent abrupt volume surges.

Key Features

• DECT wireless technology in the 1.9 GHz band for interference‑resistant connectivity and better audio isolation than standard Bluetooth office headsets.     
• Convertible wearing styles, including over‑the‑ear with earloop and over‑the‑head with headband; many deployments can also add an optional behind‑the‑head neckband.     
• Ultra‑lightweight design (well under 1 oz for the headset) to minimize fatigue for agents and knowledge workers on calls all day.     
• Long wireless range, typically up to around 350–400 ft line‑of‑sight from the base, allowing users to roam the office, retrieve documents, or consult colleagues without dropping calls.     
• Battery talk time of up to about 7 hours, supported by an adaptive power system that automatically reduces transmit power when closer to the base to conserve battery and increase density.     
• Noise‑canceling microphone with DSP to reduce background noise and enhance clarity for the far end, making conversations more professional and easier to follow.     
• Acoustic protection technology (SoundGuard‑class) that limits sudden loud sounds to safe levels to help protect hearing during long-term use.     
• Desk phone–centric connectivity via RJ‑11 interface on the base, with optional accessories enabling remote call answer/end.     
• Multi‑headset conferencing support, allowing several CS540A headsets to pair to one base for quick ad‑hoc collaboration.     
• TAA compliant variant designed to meet U.S. Trade Agreements Act requirements for government and public sector procurement.
