DESIGN AND DIMENSIONS Jabra GN2125-NC
Product Type Headset - wired
Recommended Use Phone

The Jabra GN2125-NC 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.

Impedance 300 Ohm

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 GN2125-NC offers a frequency range of 300 - 3000 Hz.

The device connected to the headphones also plays a role most times. The lower impedance value (approximately 100 to 150 Ohms) is suitable for playback from mobile phones, laptops or other portable players that do not have a powerful enough amplifier. The lower impedance will ensure that the required volume level is achieved with less power, thus extending the life of the player. However, at the same time, with lower impedance, there is more distortion of the sound. Headphones with a higher impedance of around 250 Ohms and above are then more suitable for playback from really powerful signal sources or using a headphone amplifier, otherwise the sound coming out of them might not be loud enough. At the same time, higher-impedance headphones will also ensure less distortion in the sound. In the case of these headphones, the impedance reaches the 300 Ohm value.

MICROPHONE Jabra GN2125-NC
Type Boom
Microphone Operation Mode Mono
Frequency Response 300 - 3000 Hz Worse than 99 % of headphones rated.
Total Harmonic Distortion (THD) 3%

Jabra GN2125-NC has a boom–type microphone. As with headphones, so-called harmonic distortion affects the sound quality of a microphone. Harmonic distortion above 5% is quite high and can lead to a reduction in recording quality. The average for most headphones is a distortion between 1 and 5%. For the average user, the recording quality of a headphone microphone in this interval should be perfectly adequate. Total harmonic distortion below 1% is more likely to be encountered in professional headphones. Such distortion is already considered very low and will ensure maximum recording quality. The total harmonic distortion of this microphone model is Microphone | Total Harmonic Distortion.
