The HearWiki takeAI-condensed
The STAX SR-X3 is a vintage electrostatic over-ear headphone from the mid-1970s, offering a highly transparent and detailed sound signature with very low distortion. It delivers an open, natural presentation but requires a dedicated electrostatic amplifier or energizer to operate, so it's not a plug-and-play option for casual listeners.
