Electrostatic headphones require a significant amount of additional electronics to provide the conditions under which the electrostatic effect occurs. Also, the audio signal must be transformed into a very high amplitude signal (about 600 volts peak to peak) for maximum level. This is also quite a complicated engineering task. All this makes production complicated and unattractive to the mass producer. Naturally, some manufacturers have surpassed themselves in terms of design and extras.
We have a moderate approach and want to deliver maximum quality at an acceptable price.
There is no problem with open back headphones from an acoustic point of view. The open volume at the back ensures no back pressures on the membrane that would lead to incorrect reproduction. The only minus is that you cannot isolate yourself from the surrounding noise. Closed-back headphones have their advantages where there is loud noise to cancel. Closing the back itself requires a lot of knowledge and special materials to preserve some small part of the transmitted sound.
However, when we talk about properly reproduced sound, the suppression of the rear part of the membrane is unacceptable, considering the critical hearing of audiophiles.
Are the electrostatic headphones suitable for any type of music?
Es headphones can play absolutely any sound due to the low mass of their membrane, even one that you cannot hear.
Do they have enough volume?
The power of Es headphones can be very high, it depends on the specific mechanical performance of the manufacturer, higher levels can be achieved than conventional headphones.
Do electrostatic speakers (headphones) reproduce low-end frequencies as well as other types of speakers do?
Es headphones can produce membrane displacement of close to zero hertz without problems. Their working principle allows a long stay of the membrane in any extreme position. The production of low frequencies in this case depends only on the amplifier.
