Jabra BIZ 2400 II USB Duo CC Specifications, Tests and Review

The Jabra BIZ 2400 II USB Duo CC are wired headphones. In the case of studio and professional DJ headphones, a wired connection is a standard and a necessity. In this case, connecting via cable reduces audio transmission delays and prevents unwanted battery drain as it would be in case of wireless headphones. The same is de facto true for gaming headsets. In case of headphones for normal music listening, the cable is rather a relic, although it still has its fans. However, the wireless option is much more popular for everyday use in today’s world.

The sound quality can be affected by many factors. For many users the frequency range is a key feature of headphones. The wider the range, the more detail and nuance you will hear while listening. However, every individual perceives frequencies differently, so the frequency range of headphones varies according to individual needs. The average person perceives frequencies in the range of 16 to 20,000 Hz, so headphones with a frequency range of 20 to 20,000 Hz are most commonly available. If you are looking for headphones with a good bass performance, you should aim for lower range values (bass represents frequencies up to about 256 Hz), while high range values (frequencies roughly above 2,048 Hz) will be better for reproducing high tones. The frequency range of headphones Jabra BIZ 2400 II USB Duo CC is 60 - 1600 Hz. To control the optimum playback volume you can use the manual control directly on the cable. The maximum input power of these headphones indicates how many decibels they can receive from the device without any damage. For Jabra BIZ 2400 II USB Duo CC, it is 20 mW.

Headphones consist of many important parts, including the diaphragm, which is responsible for converting electrical signals into sound. The diaphragm, with a thickness of around 6 mm, is very sensitive to changes in high frequencies but less sensitive to bass. For a relatively balanced sound profile, a medium-thick diaphragm of around 10 mm is used, which can reproduce both bass and treble. A diaphragm with a thickness of around 20 mm is not as quick to respond to changes in the audio signal, and this results in poorer bass listening. However, it is very sensitive to higher frequencies. In the case of this model, the diaphragm is the 30 mm.

Jabra BIZ 2400 II USB Duo CC has a boom–type microphone. A nice benefit of the microphone of the Headphones Jabra BIZ 2400 II USB Duo CC is the Noise Canceling technology that suppresses ambient noise and allows a clearer sound recording to be captured.
