Jabra BIZ 2400 II Duo QD Corded Headset – Ultra NC, HD Audio & Kevlar Cable for Contact Centers (2409-720-209)

The Jabra BIZ 2400 II QD Duo Ultra Noise Canceling (UNC) is a premium corded dual-ear headset for contact centers with high ambient noise — combining binaural coverage with Jabra's most aggressive background noise filtering to keep agents clearly heard even in the loudest production environments. Its 40% lighter build and unbreakable boom arm make it a durable, comfortable choice for full-day wearing.

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.
