Stax SR-L300 Electrostatic Headphones

STAX SR-L700 electrostatic earspeaker

The STAX SR-L700 electrostatic earspeaker represents the evolution of the long-standing Lambda series, combining advanced electrostatic driver technology with modern ergonomic refinements and premium acoustic engineering. Developed as a next-generation Lambda model, the SR-L700 delivers highly detailed sound reproduction with balanced tonal accuracy, expansive soundstage performance, and exceptional listening comfort.

The SR-L700 utilizes a high-quality electrostatic sound element derived from technologies originally developed for the flagship SR-009 series. The driver incorporates a hand-selected ultra-thin diaphragm together with fixed stainless steel electrodes produced using a precision three-layer etching process and heat diffusion treatment. This advanced structure minimizes distortion and resonance while improving transient response and sonic transparency. The result is rich low-frequency performance, refined midrange reproduction, and delicate high-frequency detail presented in a balanced and natural manner.

For enhanced comfort during extended listening sessions, the SR-L700 features a redesigned ARC headband assembly equipped with a 10-click adjustment mechanism inherited from the SR-009. Once adjusted, the headband maintains its position securely, reducing the need for repeated fitting adjustments. Newly designed earpads crafted from genuine lamb leather improve both wearing comfort and acoustic performance.

The included low-capacitance wide-format cable uses high-purity silver-plated 6NCu copper conductors to improve signal transmission and reduce capacitance between wires. Combined with the open-air electrostatic enclosure design, the SR-L700 provides spacious imaging, detailed clarity, and highly accurate sound reproduction for critical music listening and reference audio applications.
