Jabra BIZ 2300 Duo USB Headset

The Jabra BIZ 2300 Duo USB headset is a wired communication device built for professional voice use. It features dual ear cups for focused audio in busy environments. A dedicated Microsoft Teams button and programmable controls support quick call handling. The 7.71 ft cord allows flexible desk positioning.

Check USB port and software compatibility

Verify that your computer has an available USB-A port for the wired connection. The headset draws power and audio through this single interface. Ensure your operating system recognises standard USB audio class devices. Confirm that your softphone or collaboration platform supports wideband audio for the best quality.

Fits unified communications setups

The USB connection removes the need for a separate sound card or analogue splitter. In-line controls free you from reaching for on-screen menus to mute or answer calls. PeakStop technology protects hearing against sudden loud signals. The bendable microphone boom lets you position the capsule precisely for clear voice pickup.

Questions about this item

What comes in the box and is anything else required to use the headset?

The box contains the BIZ 2300 headset, warranty card, warning card, and quick start guide. No extra accessories are required; the USB connector plugs directly into a computer.

Should I choose the Duo version or a mono model for my environment?

The Duo ear coupling covers both ears, giving better noise isolation for busy offices. A mono version would leave one ear open for ambient awareness.

What does the 150Hz to 6800Hz voice frequency response mean for call quality?

That range is optimised for human speech, so voices sound natural and clear on calls while suppressing very low and very high frequencies.
