JABRA BIZ 2400 II DUO CC HEADPHONES WITH NOISE CANCELLATION MIC
JABRA BIZ 2400 II DUO CC HEADPHONES WITH NOISE CANCELLATION MIC
The Jabra Biz 2400 II Duo CC is a professional-grade corded headset engineered for contact center and office environments where crystal-clear communication is non-negotiable. This dual-ear design features advanced noise-cancellation technology that isolates background noise up to 20dB, ensuring your voice remains intelligible even in high-ambient environments. The headset solves the critical problem of communication clarity in busy call centers, customer service departments, and open-plan offices where ambient noise interference compromises call quality and agent productivity.
Product Overview
The Jabra Biz 2400 II Duo CC operates on a wired connection architecture that eliminates wireless latency and battery dependency, making it ideal for stationary workstations requiring 8-hour continuous operation. The dual-ear design distributes audio load evenly across both ears, reducing listener fatigue during extended call sessions. The noise-cancelling microphone utilizes dual-microphone technology with digital signal processing to suppress background noise while preserving speech frequencies between 300Hz and 3400Hz, the optimal range for voice intelligibility. The headset features a flexible boom arm with 270-degree articulation for precise microphone positioning and a leather-padded headband with adjustable tension for all-day comfort.
What distinguishes the Biz 2400 II from consumer-grade alternatives is its enterprise-grade durability and compatibility ecosystem. The CC variant indicates Cisco Unified Communications compatibility, ensuring seamless integration with Cisco IP phones and soft clients without requiring additional adapters. The headset incorporates Jabra's proprietary acoustic algorithms that dynamically adjust noise cancellation based on ambient noise levels, maintaining optimal audio clarity across varying environments. Its 40mm neodymium drivers deliver frequency response from 20Hz to 20kHz with impedance of 32 ohms, ensuring balanced audio across voice and multimedia applications.

How to Use
Begin setup by connecting the RJ9 connector to your Cisco IP phone or compatible PBX system. The quick disconnect feature allows you to unplug the headset without accessing the phone connector, enabling seamless transitions between desk phone and soft client applications. Adjust the headband tension by gently pulling the ear cups apart until the headband sits comfortably on your head without pressure points. Position the boom microphone by rotating the flexible arm toward your mouth, maintaining a distance of approximately 2-3 centimeters from your lips. Test microphone positioning by speaking normally and monitoring audio levels on your phone system; the dual-microphone array will automatically suppress background noise while capturing your voice at optimal levels.
For optimal noise cancellation performance, ensure the microphone boom is properly positioned and not obstructed by clothing or hair. The noise-cancelling algorithm requires approximately 2-3 seconds to analyze ambient noise levels and adjust suppression intensity, so allow brief stabilization time when moving between different acoustic environments. If using with Cisco soft clients, verify that audio input is routed to the headset microphone in system preferences. The coiled cable can be extended to full 2.5-meter length or retracted for desk organization; avoid wrapping the cable tightly around objects as this may damage internal conductors over time. For extended comfort during 8-hour shifts, periodically adjust the headband position and take brief breaks to prevent pressure fatigue.
Frequently Asked Questions
Does the Jabra Biz 2400 II Duo CC work with non-Cisco phone systems?
Yes, the headset is compatible with most enterprise PBX systems including Avaya, Polycom, Nortel, and Alcatel-Lucent through the standard RJ9 connector. The CC designation specifically certifies Cisco compatibility, but the wired connection architecture supports any system with a standard phone headset jack. However, we recommend verifying compatibility with your specific phone model before purchase, as some legacy systems may require adapter cables.
How effective is the noise cancellation in extremely loud environments?
The dual-microphone noise cancellation provides up to 20dB suppression of ambient noise, effectively reducing background noise from open-plan offices, call centers, and moderate industrial environments. However, in extremely loud settings exceeding 85dB sound pressure level, the noise cancellation may reach its limitation. The technology works by comparing microphone inputs and digitally inverting background noise signals; effectiveness depends on consistent ambient noise patterns rather than sudden loud bursts. For maximum performance, position the boom microphone close to your mouth (2-3cm) to maximize voice capture relative to background noise.
Can I use this headset with both desk phones and computer soft clients simultaneously?
The Jabra Biz 2400 II Duo CC connects via RJ9 to your desk phone, so simultaneous connection to both a phone system and computer requires a dual-connector adapter or switching device. Many organizations use a headset amplifier or adapter that accepts both RJ9 and USB connections, allowing you to switch between phone and soft client without unplugging the headset. Alternatively, you can unplug the RJ9 connector and reconnect it to different devices using the quick disconnect feature, which takes approximately 5 seconds. Contact our technical support team for specific adapter recommendations based on your phone system configuration.
What is the expected lifespan of the boom microphone?
The boom microphone is engineered for 3-5 years of continuous use in typical contact center environments with proper care. The flexible boom arm can withstand approximately 10,000 articulation cycles before material fatigue occurs. To extend microphone lifespan, avoid excessive bending beyond the 270-degree design range and store the headset with the boom in a neutral position when not in use. If the microphone develops crackling or noise artifacts after extended use, the boom arm may require replacement, which is available as a spare part from authorized Jabra distributors.
