At the core of the SR-L500 MK2 is the electrostatic drive principle, which fundamentally differs from conventional speaker technologies. The ultra-light diaphragm moves within an electrostatic field, enabling extremely fast and precise motion. The result is exceptionally low distortion, outstanding detail reproduction, and a natural sound signature, particularly excelling in fine dynamic nuances and spatial imaging.

The headphone features a fully open-back design, allowing sound to flow freely around the driver. This results in a more airy and natural sound, along with a wide and accurate stereo soundstage. The listener experiences a concert-like, three-dimensional audio image.

As expected from STAX, the SR-L500 MK2 is constructed from lightweight yet durable materials. The large oval ear pads distribute pressure evenly while ensuring proper acoustic sealing. The ergonomic design not only provides comfort but also positions the drivers optimally relative to the ears, which is essential for accurate sound reproduction.

Detailed and well-balanced

The SR-L500 MK2 delivers the signature STAX sound: fast, exceptionally clean, and airy. High frequencies are finely detailed, the midrange is natural and present, while bass remains tight, controlled, and distortion-free. This sound profile makes it ideal for classical music, jazz, acoustic recordings, and high-resolution digital content.
