Jabra BIZ 2400 II Mono QD Corded Headset – Noise Canceling, HD Audio & Kevlar Cable for Contact Centers (2486-825-209)

The Jabra BIZ 2400 II QD Mono NC HD Voice Universal is a corded single-ear headset tuned for HD Voice performance in multi-platform telephony environments. The "Universal" designation indicates compatibility across a broad range of desk phone systems via QD connection, making it the right choice for enterprises with mixed telephony infrastructure. Noise-canceling microphone, IP54 build quality, and the BIZ 2400 II's proven durability come standard.

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.
