Jabra BIZ 2400 II QD Mono NC 3-in-1 Wideband Specifications, Tests and Review

The Jabra BIZ 2400 II QD Mono NC 3-in-1 Wideband 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. When it comes to frequency range, the wider it is, the more detail you will hear when listening. However, the range a person can perceive is highly individual. The average person is able to perceive frequencies in the range of 16 to 20 000 Hz. So the most common frequency range you will see on the market is 20 to 20,000 Hz. Lower frequencies up to approximately 256 Hz are considered bass frequencies. Therefore, the lower the bottom value is, the better the headphones will reproduce bass. Conversely, values from approximately 2 048 Hz upwards are treble. That is why headphones with a high upper value will provide a much more accurate reproduction of high notes. Jabra BIZ 2400 II QD Mono NC 3-in-1 Wideband offers a frequency range of 100 - 6500 Hz. 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 QD Mono NC 3-in-1 Wideband, it is 20 mW.

An important part of these headphones is the diaphragm, which, simply put, converts the electrical signal into a sound. The thin diaphragm that is around 6 mm thick can react quickly to changes in the audio signal and improves high-frequency listening. However, it is less sensitive to bass. The medium-thick diaphragm of around 10 mm provides a fairly balanced sound profile, allowing you to enjoy both bass and treble. A thicker diaphragm of around 20 mm cannot react so quickly to changes in the sound signal, thus impairing bass listening. However, it is more sensitive to higher frequencies. This model features the 30 mm.

Jabra BIZ 2400 II QD Mono NC 3-in-1 Wideband has a boom–type microphone. A nice benefit of the microphone of the Headphones Jabra BIZ 2400 II QD Mono NC 3-in-1 Wideband is the Noise Canceling technology that suppresses ambient noise and allows a clearer sound recording to be captured.
