The Stax SR-30 Pro is an electrostatic earspeaker that was released in 1989. It is characterized by its use of electret technology and is designed to deliver high-quality sound reproduction. The SR-30 Pro aims for a neutral sound signature that is not overly bright or colored, allowing it to handle various genres of music effectively. It is often noted for its good midrange performance, providing a balance that many listeners appreciate. The electrostatic design allows for rapid diaphragm movement, resulting in low distortion and clear sound across frequencies. This model, along with others in Stax's lineup, typically requires a dedicated headphone amplifier due to its unique biasing requirements, using five-pin connectors.
