STAX SR-L500 Mk2

Electrostatic Open-Back Over-Ear Headphones from the Lambda Series

The STAX SR-L500 Mk2 delivers the characteristic speed, transparency and effortless detail retrieval that electrostatic headphones are famous for, combined with a smooth and musical presentation. As part of the legendary Lambda series, it offers an open and highly resolving sound signature with exceptional realism for vocals, acoustic instruments and complex recordings.

Unlike conventional dynamic headphones, the SR-L500 Mk2 uses an ultra-light electrostatic diaphragm that reacts almost instantaneously to incoming signals. The result is the unmistakable STAX presentation: fast, airy and incredibly refined, yet never artificially sharp or fatiguing.

The Mk2 revision also adopts the detachable cable system from STAX’s higher-end models, improving long-term serviceability and everyday practicality. The updated construction additionally enhances fit and wearing comfort.

Sonically, the SR-L500 Mk2 offers an expansive and spacious presentation with particularly impressive midrange performance and delicate treble extension. Bass remains tight, fast and controlled rather than exaggerated, making the SR-L500 Mk2 an excellent choice for jazz, classical music, vocals and listeners seeking maximum transparency and natural timbre.

Like all STAX electrostatic headphones, the SR-L500 Mk2 requires a dedicated electrostatic amplifier or energizer with a PRO bias connection.
