Jabra BIZ 2300 USB-C UC Duo — Wired Contact Center Headset

Plug-and-play USB-C version of the proven BIZ 2300 contact center workhorse — wideband HD Voice, air-shock noise-cancelling microphone, in-line controller and a Kevlar-reinforced cord engineered to outlast countless agent shifts.
USB-C DirectUC OptimizedWideband HD VoiceIn-Line Controller

The Jabra BIZ 2300 USB-C UC Duo (part 2399-829-189) is the direct-USB-C version of the BIZ 2300 contact center headset family — no Quick Disconnect cord required. The cable plugs straight into a modern USB-C laptop, dock or thin client, and the integrated in-line controller handles answer/end, mute and volume without touching the softphone window. The "UC" variant is tuned for unified communications platforms in General (Cisco Webex, Zoom, Genesys Cloud, Avaya, Microsoft Teams), making it a flexible default choice for mixed-platform agent fleets.

Best For
✓ Contact center agent rollouts
✓ USB-C-only modern laptops
✓ Cisco Webex / Zoom / Avaya teams
✓ Hot-desking softphone workstations
✓ All-day binaural call work
✓ Mixed-platform UC environments

Key Features

Plugs straight into a USB-C laptop, dock or thin client. No Jabra Quick Disconnect bottom cord required, so onboarding is Genuinely plug-and-play.
 
Wideband HD Voice
Tuned for HD Voice (wideband) softphone audio so the agent hears every detail clearly, helping reduce repetition and shorten average handling times.
 
Noise-Cancelling Air-Shock Mic
Aerodynamic boom with multiple small intake holes plus internal foam reduces breath and pop noise on top of standard background noise cancellation.
 
In-Line Controller + PeakStop
Integrated in-line controller handles call answer/end, mute and volume, while PeakStop instantly clips sudden loud sounds to protect agent hearing on long shifts.

Frequently Asked Questions

Do I need a separate QD cord or USB adapter?
No. The cable terminates in a USB-C plug and connects directly to a USB-C port on your laptop, dock or thin client. No Jabra Quick Disconnect bottom cord is required.
Will it work with Microsoft Teams?
Yes. The UC variant is tuned for unified communications platforms in General (Cisco, Zoom, Avaya, Genesys, Teams). For a Microsoft Teams-certified variant specifically, look at the MS-coded SKU 2399-823-189 instead.
Mono or Duo — which is this?
Duo (binaural). It covers both ears for maximum focus in busy contact center floors. If you need to stay aware of in-room sounds or take in-person walk-ups, consider the Mono USB-C UC variant (2393-829-189).
Can it be plugged into a phone or tablet?
It is designed for USB-C computers, docks and thin clients running softphones or UC apps. Some modern Android phones and USB-C tablets that support USB audio class devices may also work, but this is not officially marketed or guaranteed by Jabra.
Singular Expert Insight
Choose this USB-C UC variant if your agent fleet runs on modern USB-C laptops or docks and you want a single plug-and-play headset that works equally well across Cisco, Zoom, Webex, Avaya and Teams. If your contact center is standardized on Microsoft Teams specifically, the matching MS variant (2399-823-189) is the better choice for Teams call-control integration. If you already have Jabra QD cords deployed at every seat, the QD version (2389-820-109) saves the cost of changing cabling infrastructure.

Buyer's Guide

Buy it if
Your agents work on USB-C laptops or docks and you need one plug-and-play headset that works across multiple UC softphones without buying separate QD cords.
Skip it if
Your endpoints expose only USB-A (you'd need an adapter), your standard is strictly Microsoft Teams (pick the MS variant for native Teams call controls), or your fleet already uses QD cords (pick the QD version).
Also consider
Jabra BIZ 2300 USB-C MS Duo (2399-823-189) for Teams-first call centers, or BIZ 2300 USB-C UC Mono (2393-829-189) for agents needing single-ear room awareness.
