The STAX SR-007S Electrostatic Earspeakers represent the latest evolution of STAX’s legendary SR-007 lineage, a series revered among audiophiles for delivering some of the most transparent and lifelike headphone listening experiences available. Building on the strengths of its predecessors, the SR-007S introduces a series of refinements aimed at improving detail retrieval, tonal balance, and long-term comfort, while preserving the musical richness that has made this line a benchmark in electrostatic design.

STAX has taken a classic design and updated it with better materials, more comfort, and quieter operation, without changing what made the original so recognizable in the first place.

At the heart of the SR-007S are newly engineered diaphragms and fixed electrodes that deliver greater resolution, particularly in the higher frequencies. STAX has reduced the size of the electrode air-vent holes by around 20% compared to previous versions, a change that enhances airflow control and reduces resonance, resulting in cleaner, more natural sound reproduction. These improvements bring listeners closer to the recording, capturing micro-details and transient speed with remarkable precision.

The SR-007S also adopts an anti-resonance structure inspired by STAX’s flagship SR-X9000. A seamless stainless steel arc enhances rigidity and minimizes unwanted vibrations, while the redesigned headband includes a movable hinge for better fit and comfort. Acoustic refinements extend to the new earpads, which use soft sheepskin on the contact surface and a more absorbent inner material to reduce reflections. The pads are rotatable, providing a more personalized fit, and feature the series’ traditional brown coloration, linking the design to its heritage.

For practicality, STAX has introduced a detachable low-capacitance, six-strand OFC wide cable, making maintenance and upgrades easier. Technical performance is equally impressive, with a frequency response ranging from 6 Hz to 41 kHz, ensuring both subterranean bass control and airy treble extension. With a sensitivity of 101 dB and a 580 V “Pro” bias requirement, the SR-007S demands a dedicated electrostatic amplifier to reveal its full potential.

Sonically, the SR-007S is designed to deliver a balance of speed, clarity, and musical weight. Listeners can expect a tight, articulate low end, open and extended highs, and a midrange that carries both warmth and precision. These earspeakers are built for long listening sessions, combining luxurious materials with structural refinements that reduce fatigue while maintaining a secure acoustic seal.
