Weight 62 g Better than 86 % of headphones rated.
Earpad Material Leatherette
Protection Shock protection
Recommended Use Communication

The JPL Telecom JPL-611-PM 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 62 g.

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. JPL Telecom JPL-611-PM offers a frequency range of 100 - 6800 Hz. The sensitivity parameter determines how sensitively the headphones can receive the signal from the source. The higher the sensitivity value, the louder the headphones will be able to play with less power consumption. In general, a higher listening volume also means a higher power load for the connected device. So if you're buying headphones to listen to music from your mobile phone, for example, this is relevant to think about as you don't want to drain your phone's battery too much. Lower values around 85 dB are more suitable for listening in more quiet environments (for example, at home or in the office). Medium values of around 90 dB can provide good listening quality in noisier environments (for example, on public transport or in cafés). Headphones with high sensitivity values of around 100 dB or more are designed for really noisy environments, such as concerts. The JPL Telecom JPL-611-PM has 93 dB.

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. The maximum input power of these headphones indicates how many decibels they can receive from the device without any damage. For JPL Telecom JPL-611-PM, it is 100 mW. Total Harmonic Distortion of these headphones is Audio Output | Total Harmonic Distortion. The value quoted by the manufacturer is usually the average distortion over all reproducible frequency bands. This is not a crucial parameter to decide on when making a decision, but on the other hand, keep in mind that higher harmonic distortion can negatively affect sound quality.

JPL Telecom JPL-611-PM has a boom–type microphone. The microphone sensitivity is -32 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. 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. A nice benefit of the microphone of the Headphones JPL Telecom JPL-611-PM is the Noise Canceling technology that suppresses ambient noise and allows a clearer sound recording to be captured.
