Cisco Headset 531 wired mono overview

The Cisco Headset 531 is a wired mono headset built for professional voice communication. It connects through a Quick Disconnect RJ cable for use with Cisco IP Phones and soft clients. The over-the-head design targets workers in open offices who need clear audio and effective noise isolation during calls.

Quick Disconnect RJ fit and flexibility

The Quick Disconnect connector lets the headset detach from the cable without unplugging the phone or PC. This frees the user to step away while the call stays connected. The coiled cable provides reach at the desk and retracts to reduce clutter. Wired connectivity removes the need for batteries or charging.

50 Hz to 18 kHz range and 118 dB headroom

The 50 Hz to 18 kHz frequency response covers the full speech band and handles music playback adequately. The 118 dB sound pressure level delivers loud, clear output for noisy environments. The 90 Ohm impedance matches standard desk phone ports. The mono sound mode and single earcup limit stereo immersion for multimedia users.
