Wired Contact-Center Headset

The Jabra Biz 2400 II QD Mono NC is a wired, single-ear headset built for contact-center agents who spend the entire shift on desk-phone calls. Its Quick-Disconnect plug lets staff step away without unplugging the cord, while the flexible boom positions the microphone precisely for clear HD Voice pickup. The leatherette ear cushion and three wearing styles — headband, neckband or ear hook — keep one ear free for office awareness.

Passive Thermals and Zero Power Draw

Because the unit draws no battery or USB power, it adds no heat to the workstation and runs completely silent. The PeakStop circuit clamps sudden acoustic spikes before they reach the ear, protecting hearing during high-volume periods. Wind-noise reduction on the boom suppresses drafts from HVAC vents or open windows, so background sound stays low without active processing.

Quick-Disconnect Flexibility for Desk Phones

The QD interface connects directly to compatible desk-phone cords or amplifiers, freeing the user from a fixed cable length. A protective bag is included for safe storage between shifts. The design targets extreme, high-frequency daily use in call-centre environments; it does not suit buyers who need stereo audio, wireless mobility or a USB connection for softphone platforms.

Questions about this item

How do I connect the QD plug to my desk phone and what step is often missed?

Plug the QD connector into a compatible desk phone or QD adapter cord; the step often missed is ensuring the QD clicks fully locked so audio passes through both microphone and earpiece.

Which parts of the headset will need replacement after heavy daily use?

The leatherette size L ear cushion and the PeakStop-protected microphone boom are the components most likely to wear out first under extreme, high-frequency contact-centre use.

What is the first limitation I will hit during an all-day shift?

The single-ear, on-ear design with leatherette cushion creates heat and pressure buildup that becomes the comfort limit before any technical restriction appears.
