Jabra BIZ 2400 II Mono QD Corded Headset – Ultra NC, HD Audio & Kevlar Cable for Contact Centers (2406-720-209)

The Jabra BIZ 2400 II QD Mono 3-in-1 Ultra Noise Canceling (UNC) is Jabra's highest-performing corded contact center headset for noise-intensive environments — featuring Ultra Noise Canceling microphone technology that aggressively filters ambient noise, making it ideal for high-noise floors like collections, outbound sales, and transportation dispatch. Its 3-in-1 wearing system (headband, ear hook, neckband) and 40% lighter construction provide both versatility and comfort across long shifts.

The Telecom Spot Take

The BIZ 2400 II is Jabra's benchmark contact center headset — the choice for operations where audio quality, agent comfort during 8-hour shifts, and headset durability all matter. It's 40% lighter than comparable competitor headsets, which makes a measurable difference in agent comfort and wearing fatigue over a full day. The unbreakable boom arm and reinforced cord are engineering claims backed by Jabra's testing — for IT managers who track headset replacement costs, that durability directly reduces annual spend. NC (Noise Cancel) variants handle most office and contact center environments; UNC (Ultra Noise Cancel) variants are the right choice for high-noise floors like collections, outbound sales, or transportation dispatch. All variants include PeakStop hearing protection and carry a 3-year warranty.
