STAX SR-L500MK2
The SR-L500 MK2 is the updated entry point to STAX's Lambda series earspeakers, now featuring a detachable cable and refined driver for improved acoustic performance over its predecessor. An excellent introduction to what electrostatic listening sounds like.
Type and Technology
Over-ear, open-back, electrostatic. MLER (Multi-Layer-Electrode) fixed electrode from the Lambda series driver family. Pro bias (5-pin) connection. Detachable cable, a new addition for the MK2. Requires a compatible electrostatic energizer.
Sound Character
Airy, detailed, and effortlessly fast in the way only electrostatics can be. The SR-L500 MK2 delivers the core STAX electrostatic experience at the most accessible price in the Lambda series, with excellent treble extension, natural midrange, and a transparency that immediately distinguishes it from conventional dynamic and planar headphones.
Best For
First-time electrostatic listeners and those building a STAX system on a budget, pairs well with the SRM-400S or SRM-500T energizers.
