Stax SR-007S Electrostatic Earspeaker

Stax SR-007S Electrostatic Headphones

The Stax SR-007S Electrostatic Headphones are engineered to deliver refined electrostatic audio performance through newly developed acoustic technologies, enhanced structural rigidity, and premium comfort-oriented materials. Building upon the legacy of the SR-007 and SR-007A designs, the SR-007S introduces updated diaphragms and redesigned fixed electrodes that significantly improve sound detail clarity while preserving the deep, rich tonal balance that defines the series.

The newly developed large circular fixed electrodes utilize a high-precision etching process with approximately 20% smaller air vent holes compared to previous models. This design optimizes airflow characteristics and acoustic behavior, contributing to improved resolution, smoother transparency, and more accurate sound reproduction across the frequency spectrum. The electrostatic driver system maintains the speed and transient accuracy expected from reference-grade electrostatic headphones while presenting an expansive and immersive soundstage.

The SR-007S also incorporates the advanced ARS (Anti Resonance Structure) inspired by the flagship SR-X9000. Constructed from a seamless stainless steel plate, the arc assembly increases structural rigidity while reducing unwanted resonance and vibration. The redesigned movable hinge section improves fit and stability, allowing the headphones to conform naturally for extended listening comfort. A specialized rubber head pad attachment system preserves the signature self-adjusting fit associated with the 007 series.

Premium rotating earpads crafted from genuine sheepskin improve acoustic absorption and minimize unwanted reflections, enhancing spatial imaging and tonal precision. The redesigned inner earpad structure further refines soundstage depth and perspective. A detachable low-capacitance cable system supports easy maintenance and long-term usability, making the SR-007S a highly refined electrostatic headphone solution for demanding audiophile listening environments.
