STAX SR-009S Open-Back Electrostatic Headphones

This is the STAX flagship. The 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.

The SR-009S employ a diaphragm made of ultra-thin super engineering plastic film. The light mass has realized a high transient characteristic throughout the entire audio spectrum.Aluminum is abundantly used at the frame to realize high-quality sound, rigidity, and lower weight. Almost every part of the SR-009 is manufactured through precise machine processing.

The earpads are made by hand and feature both leather and cushion material with moderate elasticity, enabling hours of comfortable listening. The headband is equipped with a position adjustment mechanism of 10-step slider and corresponds to the wide range of cranial forms with individual differences.
