STAX SR-003 MK2

STAX's compact in-ear electrostatic earspeaker, the SR-003 MK2 brings the effortless speed and transparency of electrostatic transducer technology to an in-ear format, making it one of the most technically unique IEMs available at any price.

Type and Technology

In-ear, electrostatic. Miniaturized electrostatic transducer in a comfortable in-ear form factor. Pro bias (5-pin) connection, requires a compatible STAX Pro-bias energizer with an in-ear output. Cannot be driven from a standard headphone output.

Sound Character

Airy, fast, and remarkably transparent for an in-ear design. The SR-003 MK2 brings the electrostatic characteristics of low mass and negligible distortion to a portable format, delivering a uniquely open and effortless presentation that conventional dynamic or balanced armature IEMs cannot replicate.

Best For

STAX system owners who want an in-ear electrostatic option to complement their existing energizer setup, or audiophiles curious about what electrostatic technology sounds like in an IEM format.
