Stax SR-L500MK2 Electrostatic Headphones

STAX SR-L500MK2 electrostatic earspeaker

The STAX SR-L500MK2 electrostatic earspeaker is part of the Advanced Lambda series, delivering refined electrostatic audio performance with enhanced durability, comfort, and signal transmission. Designed for listeners seeking high-resolution sound reproduction, the SR-L500MK2 combines precision electrostatic driver technology with lightweight ergonomic construction for immersive and accurate listening.

The SR-L500MK2 utilizes a push-pull open-back electrostatic sound element featuring a hand-selected ultra-thin diaphragm and durable stainless steel fixed electrodes. This design enables highly detailed sound reproduction with fast transient response, wide frequency extension, and low distortion across the audio spectrum. The balanced tuning delivers deep bass response, smooth midrange clarity, and delicate high-frequency detail for natural and transparent sound performance.

A major enhancement in the MK2 version is the detachable HiFC cable system, which improves maintenance flexibility and overall usability. The HiFC (High-Performance Pure Copper) cable structure uses specially developed high-purity copper conductors arranged in a low-capacitance wide configuration to optimize signal transfer and electrostatic driver performance. The upgraded aluminium yoke assembly improves structural rigidity and enhances wearing stability compared to previous designs.

Comfort is further improved through the 10-click adjustable headband mechanism derived from higher-end STAX models, allowing consistent positioning and long-term listening comfort. High-quality synthetic leather earpads provide a secure and comfortable fit while supporting acoustic performance. Designed for use with STAX 580V DC Pro bias electrostatic amplifiers, the SR-L500MK2 delivers the speed, openness, and spacious imaging characteristic of premium electrostatic headphone systems.
