Jabra Biz 2400 II Mono 3-in-1 Headset | QD | NC | Wideband – 2486-820-209

Product Overview

The Jabra Biz 2400 II Mono 3-in-1 (2486-820-209) is a professional-grade corded headset engineered for contact centers and high-volume call environments. Featuring wideband audio up to 6,800Hz, this headset delivers crystal-clear HD voice quality on both ends of the call. The noise-canceling microphone with air shock protection filters out background noise and eliminates unwanted pops, ensuring your customers hear only your voice.

Designed for all-day comfort, the Biz 2400 II is up to 40% lighter than competing headsets with soft leatherette ear cushions and padded headband. The versatile 3-in-1 wearing style allows agents to choose between headband, neckband, or ear hook configurations for personalized fit. The Quick Disconnect (QD) connector provides instant connectivity to a wide range of desk phone systems when paired with the appropriate bottom cable.

Built for demanding environments, the Biz 2400 II features an unbreakable 360° FreeSpin boom arm and Kevlar-reinforced cord that withstands daily wear from office chair wheels and sharp objects. PeakStop technology provides acoustic shock protection by filtering out sounds above 118dB before they reach your ears, protecting agent hearing during extended call sessions.
