Electrostatic headphones use a unique technology that relies on an electrically charged diaphragm to produce sound. This diaphragm is placed between two conductive plates, creating an electrostatic field. When audio signals are applied, the diaphragm moves, generating sound waves that are known for their clarity and detail. These headphones are often praised for their wide frequency response and low distortion, making them popular among audiophiles. However, they typically require a dedicated amplifier, known as an electrostatic headphone amplifier, to function properly, which can add to the overall cost and complexity of the setup.
