Jabra BIZ 2400 II QD Duo NC Wideband Balanced - Headset

Jabra BIZ 2400 II QD Duo NC Wideband Balanced - Headset

The Jabra BIZ 2400 II QD Duo NC Wideband Balanced is a professional stereo headset engineered for exceptional audio clarity and all-day comfort. “Duo” means dual‑ear (stereo) – perfect for immersive calls and music. “NC” stands for noise‑canceling microphone, which blocks out background chatter. “Wideband” audio delivers a richer frequency range (150Hz–6.8kHz) for natural, lifelike conversations. “Balanced” ensures both ears receive equal, consistent sound, reducing listening fatigue. The Quick Disconnect (QD) feature lets you unplug from the cord without removing the headset. With leatherette memory foam ear cushions and a durable, reinforced cord, this headset is a top choice for call centers, critical listening environments, and professionals who spend hours on the phone.

How It Works

Connect the RJ9 plug to your desk phone’s handset port or a Jabra Link USB adapter (sold separately) for PC use. The Quick Disconnect (QD) allows you to detach the cord while wearing the headset – ideal for stepping away from your desk without taking off the headset. The noise‑canceling microphone boom rotates 270° for left‑ or right‑side wear and reduces background noise up to 20dB. The stereo speakers with wideband audio deliver natural, detailed sound for calls and multimedia. The balanced design ensures equal volume and fidelity in both ears, so you don’t strain to hear. The inline control pod (on some cords) gives you volume and mute. For other professional audio solutions, check out our selection of corded headsets at FindHeadsets.

Compatibility & Design

The Jabra BIZ 2400 II QD Duo NC works with virtually any desk phone (RJ9 handset port) and with PCs via a Jabra Link USB adapter (sold separately). It is compatible with all major softphones (Teams, Zoom, Webex) when used with a USB adapter. The headband is adjustable with soft leatherette padding, and the ear cushions are memory foam covered in leatherette – replaceable for extended life. The “wideband” frequency response (150Hz–6.8kHz) provides superior voice clarity over standard narrowband headsets. The “balanced” audio design means both channels are matched for consistent sound pressure. The headset is black, weighs approximately 5 ounces, and the QD connector is gold‑plated. The “II” version features improved speakers and durability.

Why Choose This Product

The BIZ 2400 II QD Duo NC Wideband Balanced stands out for its combination of wideband audio, noise cancellation, and balanced stereo. Wideband makes voices sound natural – no more muffled or tinny calls. The balanced design prevents uneven volume between ears, reducing fatigue during long listening sessions. The noise‑canceling microphone ensures your callers hear only you, even in noisy offices. Quick Disconnect adds convenience for multi‑taskers. For call center agents, transcriptionists, or anyone who uses a headset for hours, this model provides exceptional comfort and audio fidelity. Compared to mono or narrowband headsets, the difference in clarity is immediately noticeable. The replaceable ear cushions extend the product’s life, making it a cost‑effective long‑term investment.
