Recommended Use | Phone |
The JPL Telecom JPL-402S-PB 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 headphones are designed as on-ear. On-ear headphones are generally lighter. However, their design has fewer isolation capabilities, and therefore, for example, more sound can be let in and out compared to around-ear headphones. The weight of the headphones is 78 g.

The sound quality can be affected by many factors. Overall, these headphones can reproduce sound up to 129 dB. However, be careful. Repeatedly playing music continuously at really high volumes can damage your hearing.
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.
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 55 mm.
You will also definitely appreciate the special design of the construction that creates a seal that further blocks out ambient noise and which contributes to undisturbed music listening.

JPL Telecom JPL-402S-PB has a boom–type microphone. The microphone sensitivity is -43 dB. A lower microphone sensitivity will generally ensure that even quieter sounds are caught. On the other hand, in noisier environments, distortion of the recording may occur. With a higher sensitivity, the microphone will not distort the recording even in noisy environments. On the other hand, the microphone will not pick up quieter sounds. So it depends on the environment and the purposes you plan to use the headphones for. A nice benefit of the microphone of the Headphones JPL Telecom JPL-402S-PB is the Noise Canceling technology that suppresses ambient noise and allows a clearer sound recording to be captured.
