Jabra BIZ 2400 II Duo UNC QD headset

The Jabra BIZ 2400 II Duo UNC is a wired VoIP headset built for professional voice communication. It uses a Quick Disconnect interface that requires a separate lead to match your desk phone or softphone setup. Dual ear cups and an adjustable headband provide all-day wearing comfort in busy offices.

Suited to open-plan workers needing clear calls

The noise-cancelling microphone and PeakStop protection suit agents in loud environments who need reliable audio. The Kevlar-reinforced cord and 360-degree Freespin boom arm withstand heavy daily use. Buyers who need a headset with a permanently attached connector or integrated USB plug should look elsewhere.

Quick Disconnect connection decides compatibility

The headset terminates in a QD plug, so you must buy the correct Jabra GN lead for your specific desk phone, softphone or mobile device. Without that matching cable the headset cannot connect to any system. Verify the lead part number before ordering.

Questions about this item

Should I choose the Duo version or a mono option for my open-plan office?

The Duo model covers both ears, so the Ultra Noise Cancellation microphone and HD voice audio block more ambient sound than a single-ear design would.

How does the noise-cancelling microphone perform when I am on a call in a busy contact centre?

It filters out surrounding chatter and the PeakStop circuit clamps any sudden loud spikes before they reach your ears, keeping conversations clear.

What does the Quick Disconnect (QD) connection actually let me do day to day?

The QD plug lets you unclip the headset instantly and swap between compatible desk-phone or smartphone cords without unplugging the base cable.
