Jabra Biz 2400 II Mono 3-1

Jabra Biz 2400 II Mono 3-in-1

The Jabra Biz 2400 II Mono 3-in-1 is a professional wired headset designed for professionals who use multiple devices – desk phone (RJ9), PC (USB), and mobile (3.5mm). The mono (single‑ear) design keeps you aware of your surroundings, perfect for reception desks, call centers, and home offices. With a noise‑canceling microphone, wideband audio (150Hz–6.8kHz), and Quick Disconnect (QD), this headset delivers crystal‑clear calls and all‑day comfort. The “II” version offers improved speakers and durability over the original Biz 2400.

How It Works

The headset includes three interchangeable cables: an RJ9 coiled cord for desk phones, a USB‑A cord for PCs (plug‑and‑play, UC certified), and a 3.5mm cord for smartphones and tablets. The Quick Disconnect (QD) lets you swap cables without removing the headset. The noise‑canceling microphone boom rotates 270° for left‑ or right‑side wear and reduces background noise (up to 20dB). The wideband speaker delivers natural, rich audio for calls. The inline control pod (on USB and 3.5mm cables) gives you volume, mute, and call answer/end.

Compatibility & Design

The Jabra Biz 2400 II Mono 3-in-1 works with desk phones (RJ9 handset port), PCs/Macs via USB, and smartphones/tablets via 3.5mm jack. It is UC certified for Microsoft Teams, Zoom, Google Meet, Cisco Webex, and other softphones when used via USB. The headband is adjustable with soft leatherette padding, and the ear cushion is memory foam covered in leatherette – replaceable. Wideband audio (150Hz–6.8kHz) provides superior voice clarity. The headset is black and weighs 3.5 ounces. The QD connector is gold‑plated.
