Jabra Biz 2400 II QD Mono Headset

The Jabra Biz 2400 II QD Mono UNC is a wired monaural headset built for professional voice communication. It connects via Quick Disconnect for desk phone use and weighs 1.59 oz without the cord. The HD Voice frequency band covers 300 Hz to 3.40 kHz for clear speech reproduction.

Quick Disconnect fits desk phone workflows

A Quick Disconnect interface lets the headset detach from the desk phone cord instantly, freeing the user to step away without removing the headset. The package includes an ear hook, neckband, headband, leather-feel ear cushion, clothing clip and protective bag so each wearer can choose their preferred wearing style.

Upgrades basic mono headsets in noisy offices

This model replaces standard mono headsets when background noise is the main problem. The ultra noise-cancelling microphone and PeakStop protection meet G616 limits, making the jump worthwhile for call centres and open-plan teams that need durable cords and a 360-degree Freespin boom arm.
