NEW RELEASE! ships in early December 2025
The SR-009, the origin of STAX's current high-end models. Equipped with a large circular sound unit featuring innovative fixed electrodes, this model led the high-end headphone culture for a long time. Production had ceased with the arrival of the new flagship model, but now, in response to numerous requests from fans worldwide, it is making a comeback. With changes to the body color, cable material, and unit case, it is now available at a more accessible price than at its original launch.
Multilayer fixed electrode MLER (Multi-Layer-Elect-Rords) established with SR-009 has evolved to MLER 2. The finish and etching process that smoothes the edge of the electrode opening reduces air resistance and further improves sound permeability. Also, the electrodes themselves are gold plated with high specific gravity to minimize the resonance of the ultra-thin electrode. At the same time, due to the effect of reducing the electric resistance of the electrode itself by gold plating, we have opened up a new ground for high speed, clarity, silky details, and powerful texture.

LAST BATCH!
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-L300 advanced Lambda series Earspeaker.
The SR-003MK2 is a 5-pin PRO bias type in-the-ear earspeaker, and can be used by connecting to a driver unit having 5-pin PRO bias output socket. The redesigned ear canal type structure of the SR-003 enables you to enjoy excellent electrostatic sound quality without covering your ears. The SR-003MK2 connects to STAX driver units or adapters equipped with 5-pin type PRO bias output.
New flagship Earspeakers equipped with newly fixed electrode MLER-3 technology.
