JPL Telecom MGC012121 Specifications, Tests and Review

The JPL Telecom MGC012121 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.

This type of headphones has a design that surrounds the entire ear to improve isolation from external noise. As a result, they provide a great quality of listening without interference. However, unlike on-ear headphones, they are usually heavier and less suitable for frequent wearing. The weight of the headphones is 39.5 g.

The sound quality can be affected by many factors. When it comes to frequency range, a wider range will allow more detail to be heard during your listening session. However, it is important to note that the ability to perceive frequencies varies from person to person. The average person is able to hear frequencies in the range of 16 to 20 000 Hz. That is why headphone manufacturers usually focus on the 20 to 20 000 Hz range. If the lower values are lower, headphones are better able to reproduce bass tones, as these represent frequencies up to approximately 256 Hz. Conversely, values from 2 048 Hz upwards are treble. Thus, headphones with a high upper limit will provide a much more accurate reproduction of high tones. Headphones JPL Telecom MGC012121 have 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 150 Ohm value.

JPL Telecom MGC012121 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.
