The first SR-Lambda series was introduced 36 years ago and it has further developed into a new-generation SR-Lambda with its newly designed enclosure - the new SR-L500 advanced Lambda series Earspeaker.

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.

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 earpad design is carefully hand crafted with high quality synthetic leather for utmost comfort for hours of music enjoyment as well as sound performance.

The latest version of Stax's classic Lambda earspeakers thrill with incredible clarity and purity of sound.
-Winner - Home Headphones of the Year Under $5000, 2022 Sound + Image Awards, What Hi-Fi?
The level of micro-detail was mesmerizing, and the way the sound floated effortlessly reminded me of how the atmosphere is at 10,000 ft.; so clear and delicate. Everything plays effortlessly; turning up the volume doesn't produce any distortion. The bass was punchier and more present than I thought it would be, given the reputation of both electrostatic speakers and headphones not being able to reach deep. Perfect for jazz and vocals...
