Jabra Biz 2300 Duo Headset

The Jabra Biz 2300 is a wired on-ear headset built for unified communications. Dual ear cups help users focus in noisy offices or contact centres. A flexible boom arm rotates 360 degrees thanks to the FreeSpin mechanism so you can set the microphone exactly where you need it. Kevlar reinforcement protects the cable from daily wear and tear.

Installation and common issues

Plug the USB connector into a host device and the headset is recognised without extra drivers. Position the boom close to the mouth; the air-shock design with internal foam reduces breathing noise automatically. PeakStop technology clamps sudden loud sounds before they reach your ears. If the microphone picks up too much background, adjust its angle using the free-rotating arm.

Pre-purchase checks

Verify that your computer or desk phone offers a standard USB-A port for the wired connection. Confirm that your softphone or UC platform supports wideband audio to benefit from HD Voice clarity. Ensure the on-ear form factor suits the user's comfort preference for extended shifts. The headset is mono-optimised for voice, not stereo music playback.
