Jabra Biz 2400 II Mono 3-in-1, NC, Wideband

Jabra Biz 2400 II Mono 3-in-1, NC, Wideband

The Jabra Biz 2400 II Mono 3-in-1, NC, Wideband is a professional wired headset that adapts to any device – desk phone (RJ9), PC (USB), or mobile (3.5mm). The mono (single‑ear) design keeps you aware of your surroundings, making it perfect for reception desks, call centers, and home offices. “NC” stands for noise‑canceling microphone, which filters out background chatter. “Wideband” audio delivers clearer, more natural conversations (150Hz–6.8kHz) than standard narrowband headsets. With Quick Disconnect (QD), leatherette ear cushion, and all‑day comfort, the Biz 2400 II is a workhorse for professionals who switch between multiple communication devices.

How It Works

The headset includes three interchangeable cables: an RJ9 coiled cord for desk phones, a USB‑A cord for PCs and Macs, 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 rich, natural audio for calls and multimedia. The inline control pod (on the USB and 3.5mm cables) gives you volume, mute, and call answer/end.

Compatibility & Design

This 3‑in‑1 headset works with virtually any device: desk phones with RJ9 handset port, PCs/Macs via USB (plug‑and‑play, UC certified), and smartphones/tablets with 3.5mm jack. It is compatible with Microsoft Teams, Zoom, 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. The wideband audio (150Hz–6.8kHz) ensures clearer calls than standard 300Hz–3.4kHz narrowband. The headset is black, weighs 3.5 ounces, and the QD connector is gold‑plated. The “II” version has improved speakers and durability over the original Biz 2400.

Why Choose This Product

The Biz 2400 II Mono 3-in-1 is ideal for professionals who use multiple devices daily. Instead of buying separate headsets for your desk phone, PC, and mobile, one headset does it all. The wideband audio makes a noticeable difference – voices sound more natural and less muffled compared to standard office headsets. The noise‑canceling microphone is exceptional, blocking out keyboard clicks and office chatter. The Quick Disconnect adds convenience when switching between cables or stepping away from your desk. For IT managers, this headset simplifies inventory – one model covers all user needs. The replaceable ear cushion extends product life.
