DESIGN AND DIMENSIONS JVC HA B7SL
Product Type Headphones - wired - 3.5 mm jack
Colour Silver

The JVC HA B7SL 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 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 JVC HA B7SL have a frequency range of 10 - 20000 Hz. The JVC HA B7SL reaches the sensitivity values of 108 dB. The sensitivity of the headphones expresses the ability of the headphones to pick up the signal from the source and reproduce it with sufficient volume. The higher the sensitivity, the more easily the signal is converted to sound and the louder the headphones are able to play at a lower power consumption. It is important to remember that high listening volume can consume more energy from connected devices. So if you want to listen to music from your cell phone, it's better to choose headphones with low sensitivity to avoid draining your phone's battery too much. Headphones with a lower sensitivity value (around 85 dB) are better suited for listening in quiet environments, while medium values (around 90 dB) allow for quality listening in noisy environments such as public transport or cafes. Headphones with a high sensitivity value (100 dB or more) are designed for use in really noisy environments such as concerts

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 32 Ohm value.

The headphones are composed of many various components, one of the most important is the diaphragm. Diaphragm transforms the electrical signal into sound and therefore its quality affects the overall listening experience. There are three types of diaphragms: thin, medium-thick, and thicker. A thin 6 mm thick diaphragm responds quickly to high frequencies but less sensitively to bass. The medium-thick 10 mm diaphragm provides a balanced sound profile, allowing you to enjoy both bass and treble. The thicker 20 mm diaphragm is more sensitive to higher frequencies but has a poorer bass response. These headphones are equipped with the 30 mm.
