Jabra BIZ™ 2300 USB Duo, Type: 82 E-STD, Microphone boom: 360 degrees (headband), USB connector, with mute-button and volume control on the cord, Microsoft certified

The Jabra Biz 2300 Duo MS USB is a professional corded contact centre headset in its Microsoft-optimised, double-eared form. It plugs into a USB-A port and is tuned for Microsoft UC clients, making it a straightforward pick for teams standardised on the Microsoft calling stack.

Covering both ears with leatherette cushions, it helps agents shut out a busy floor and focus on the caller. If your platform is not Microsoft-based, or you keep one ear open, look at the Biz 2300 Mono MS USB for single-eared wear, or the Biz 2300 Duo QD for desk phone connection.

Frequently asked questions

What does the MS in the name mean?

MS marks the Microsoft-optimised variant, tuned for Microsoft UC clients such as Skype for Business and Teams environments. If your organisation uses another softphone platform, we can advise whether the MS or standard variant suits you better.

Do I need any extra cables?

No — the USB variant connects directly to a USB-A port on your PC. Only the QD versions of the Biz 2300 need a separate bottom cable.

Why choose duo rather than mono?

Duo helps agents block out background noise on a busy floor. If your staff need one ear open for the room, the mono version is otherwise identical.
