Electrostatic headphones are a type of audio device that use electrostatic principles to produce sound. Unlike traditional dynamic headphones, which rely on moving coils and magnets, electrostatic headphones utilize a thin diaphragm placed between two electrically charged plates. When an audio signal is applied, the diaphragm moves, creating sound waves. These headphones are known for their exceptional sound quality, offering a wide frequency response and low distortion. However, they typically require a specialized amplifier, known as an electrostatic headphone amplifier, to function properly. This makes them less portable but highly valued by audiophiles for their clarity and detail.
