Jabra BIZ 2400 II USB Mono BT Specifications, Tests and Review

The wireless connection option offers freedom of movement while increasing the comfort of use. The detachable cable then provides a listening alternative in the event of a low battery caused by wireless listening.

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