FAQs on Electrostatic Headphones
Electrostatic headphones are very different from the conventional dynamic headphones. They have a completely different working principle. They are superior to conventional headphones in terms of precision, audio quality and detailing.
In electrostatic headphones, there are very thin diaphragms. The entire mechanism works when some electric charge is transferred to a film that is placed between two metal plates. On the application of audio voltage on these plates, they develop static cling and repulsion, which results in the movement of the film.
The basic purpose of an amplifier is to raise the audio voltage generated from the source device. This voltage is generally low. So, the headphone needs an amp to increase this voltage to a level from where it is converted to sound waves through the speakers placed inside the headphones.
One simple way to drive electrostatic headphones is by increasing the voltage that is being generated from the source device through the amp.
The amps used in electrostatic headphones are based on costly high-tech technology. Plus, the number of users of electrostatic headphones is very less in the market. There is not enough competition as well. This tends to elevate the price of these headphones.
Conclusion
Investing in electrostatic headphones should give the expected returns. And in this case, sound and comfort are the only two returns you would expect.
If you want to go by our recommendation, we would suggest going with the STAX SR-007A MK2, HIFIMAN Jade II, and Koss ESP-950.
