Jabra Biz 2300 USB UC Duo

The Jabra Biz 2300 USB UC Duo is a wired stereo headset designed for contact centre professionals. It connects via USB to all leading unified communications platforms and softphones. The dual-ear design helps users focus in busy open-plan offices. A 360-degree rotating boom arm and Kevlar-reinforced cord withstand daily heavy use.

Suited to high-volume desk workers.

This headset suits agents who spend full shifts on calls and need durable, all-day comfort with two ear cushions included. Buyers who need wireless freedom to move away from the desk should consider other options. The fixed USB cable also limits use with mobile devices or desk phones lacking a USB port.

USB connectivity for UC platforms

The single specification that decides fit is the USB interface, which provides plug-and-play compatibility with major softphone and UC applications. No additional drivers or adapters are required for standard computer-based calling. Ensure the workstation has an available USB port before purchase.

Questions about this item

Which USB port on my computer does the Jabra Biz 2300 USB UC Duo need?

Any standard USB-A port provides both power and audio for the headset.

Will the 360-degree FreeSpin boom arm interfere with my existing desk phone handset?

The boom rotates fully without contact, so it clears a desk phone cradle or any nearby hardware.

How do I confirm HD voice and the noise-cancelling mic are active after plugging in?

Open your UC softphone audio settings, select the headset as input and output, then make a test call — clear speech and suppressed breathing pops show both features are working.
