View RequirementsProduct Overview
The Jabra Biz 2400 II Duo (2409-820-205) is a professional-grade corded headset engineered for contact center excellence. Featuring dual speakers with 30mm Dynamic PureSound drivers and a noise-canceling microphone, this headset delivers crystal-clear HD audio on both ends of every call. The duo design provides immersive stereo sound while reducing ambient noise, helping agents focus on customer conversations in busy environments.
Built for demanding contact center environments, the Biz 2400 II features an unbreakable FreeSpin boom arm with 360-degree rotation and a Kevlar-reinforced cord that withstands daily wear from office chair wheels and sharp objects. At just 87g with cord, it's 40% lighter than competing headsets, with super-soft leatherette ear cushions and padded headband for all-day comfort.
The Quick Disconnect (QD) connector provides instant connectivity to desk phones and softphones when paired with compatible bottom cables or adapters such as the Jabra Link 260 or GN1200. PeakStop technology protects hearing by filtering sounds above 118dB, while the Air Shock microphone design reduces breathing noise and pops for professional call quality.
