HP CS545 Wireless DECT Headset

The HP CS545 is a DECT wireless headset operating at 900 MHz with a range of up to 400 ft. It is designed for office professionals who need hands-free communication while moving around the workspace. The convertible design offers three wearing styles: over-the-ear, over-the-head, and behind-the-head. A noise-cancelling microphone reduces background sound for clearer calls.

Sustained daily use and conference flexibility

The adaptive power system optimises performance for extended range and talk time during long workdays. Users can roam confidently up to 400 ft from the base unit without signal loss. The system supports conferencing up to four headsets on a single base for team collaboration. Electronic Hook Switch capability enables reliable remote call answering and ending throughout the shift.

Upgrade from wired or single-style headsets

This headset replaces tethered desk phone handsets that restrict movement to the length of a cord. It also upgrades single-style headsets that cannot adapt to different comfort preferences. The jump is worthwhile for teams needing multi-user conferencing on one base and remote call control via EHS or HL10 lifter. It is not for buyers who need Bluetooth connectivity to mobile devices or unified communications platforms without a desk phone base.

Questions about this item

Does the CS545 headset generate noticeable heat or noise during all-day use?

The DECT headset runs silently with no fan and produces negligible warmth during extended calls.

What desk-phone interface must I already have for the Electronic Hook Switch to work?

An EHS-compatible desk phone with the matching EHS cable is required for remote call control.

Can I pair this 900 MHz DECT headset with a legacy analogue phone that lacks EHS?

Yes — use the HL10 Handset Lifter on the older phone to answer and end calls remotely.
