The Jabra Biz 2400 II is a wired headset designed for professional communication environments. Its duo, over-ear construction provides passive noise isolation, allowing users to focus on conversations. The 30 mm drivers are specifically tuned for vocal frequencies, operating within a 60 to 1600 Hz range to deliver clear speech reproduction. It connects directly to a computer via a standard USB interface, ensuring a reliable and straightforward setup for call-centric applications. The lightweight 77-gram frame, combined with leatherette and foam earpads, is intended for extended use throughout the workday.
For clear communication, the headset incorporates a noise-canceling boom microphone that filters out ambient background sounds. This feature is augmented by integrated Digital Signal Processing (DSP) to further refine audio for both the user and the listener. An in-line control unit is built into the 2.3-meter cable, offering direct access to volume adjustments and a microphone mute function. The microphone boom is also designed to fold away when not in use. A carrying case is supplied with the headset for protection during transport or storage.
