STAX SR-L500MK2 Electrostatic Headphones High-Fidelity Earspeakers for Audiophiles

The STAX SR-L500MK2 represents a significant evolution in electrostatic headphone design, offering audiophiles and sound professionals an immersive, high-resolution listening experience. As a member of STAX’s prestigious Lambda series, the SR-L500MK2 features push-pull open-back oval electrostatic drivers that deliver ultra-fast transient response, remarkable detail retrieval, and a wide, natural soundstage.

At the heart of the SR-L500MK2 is STAX’s proprietary electrostatic technology, which uses an extremely thin diaphragm suspended between two charged plates. This design allows for near-instantaneous diaphragm movement, resulting in exceptional clarity, accuracy, and musicality far beyond conventional dynamic or planar magnetic headphones.

With a frequency response of 7Hz to 41,000Hz, the SR-L500MK2 captures the full harmonic range of instruments and vocals — from the deepest bass notes to shimmering highs. It offers a sound pressure sensitivity of 101dB, making it both responsive and efficient when paired with a suitable electrostatic amplifier such as the STAX SRM-500T or SRM-D50.

Comfort and build quality are equally impressive. The SR-L500MK2 features high-quality synthetic leather ear pads, a lightweight frame, and a HiFC 6-strand low-capacitance copper cable for clean signal transmission. A click-adjustable headband ensures a comfortable fit for long listening sessions, while durable construction ensures years of reliable performance.

FEATURES

• Top Quality Sound Element
  Hand selected thin-film diaphragm as well as tough stainless fixed electrodes has been employed for the SR-L500. Thus, rich deep bass response, delicate high frequency and soothing mid-range has been achieved in a balanced manner.
  
• 10-Click Type Headband Assembly
  The headband (ARC) assembly of the SR-L500 is equipped with 10-click slider mechanism for head pad height adjustment adopted from SR-009 and SR-507. Once adjusted, the slider always maintains its optimal position to make readjustment unnecessary. This enables you to enjoy hours of pleasant music listening with utmost comfort.
  
• New Low Capacitance HIFC Wide Cable
  High performance pure copper HiFC™ developed by Hitachi employs the core wires. HiFC has various advantages, including similar sonic characteristics as used in SR-009 and SR-L500 6N high purity 99.99999% copper wires. The entire cable are then arranged in a flat, wide format configuration to lower the capacitance between each wires and finished with the most suitable structure to drive the earspeaker.
  
• New High Quality Synthetic Leather Earpads:
  New earpad design is carefully hand crafted with high quality synthetic leather for utmost comfort for hours of music enjoyment as well as sound performance.
