Contact-centre mono headset

The Jabra Biz 2400 II Mono NC is a corded headset built for contact-centre agents who spend all day on calls. Its noise-cancelling microphone filters ambient and breathing sounds so the far end hears clear speech. A reinforced cord and unbreakable boom arm withstand constant handling in high-volume environments. Quick Disconnect plug gives instant compatibility with a wide range of desk-phone systems.

Agents needing single-ear awareness

This mono design suits professionals who must hear colleagues or announcements while staying on a call. Buyers who want stereo audio for multimedia or music playback should consider a dual-speaker model instead. Teams requiring wireless freedom will need a different form factor because this unit is tethered by its cord. The QD connection also means a separate bottom cable is required for each phone platform.

Sustained comfort over long shifts

At 40% lighter than competing headsets the Biz 2400 II reduces neck strain during hundreds of daily calls. Super-soft leatherette headband and ear cushion distribute pressure evenly so agents stay productive through marathon sessions. Acoustic shock protection blocks sudden loud spikes to safeguard hearing during extended use. Durable construction keeps the headset reliable across back-to-back shifts without performance drop-off.

Questions about this item

What desk phone system or QD adapter do I need to plug the 2403-820-205 headset into?

The headset uses a Quick Disconnect plug, so you need a compatible desk phone or a separate QD adapter cable that matches your phone's port.

Will the noise-cancelling microphone on this 2400 II Mono NC model still filter background sound when I keep my older desk phone?

Yes, the microphone's noise-cancelling and breathing-noise filtering work independently of the phone, so they function with any desk phone you connect via the QD plug.

How can I confirm the acoustic shock protection is active after I connect the 2403-820-205?

Make a test call and listen for sudden loud tones being suppressed; the protection engages automatically on any line once the QD connection is secured.
