Stax SR-009S Electrostatic Headphones
The SR-009S is the latest version of the flagship Stax headphones. They are considered by many to be the best-sounding headphones in the world.
They feature a number of innovative technologies that contribute to their outstanding sound quality. The multilayer fixed electrode (MLER) 2 technology reduces air resistance and improves sound permeability. The ultra-thin super engineered plastic film diaphragm provides a high transient characteristic throughout the audio spectrum. And the redesigned main body further reduces resonance, resulting in a more consistent sound.
Built to last, they're made of high-quality materials, such as aluminium and high-purity copper wire. The earpads are made of natural leather & cushioning material, providing hours of comfortable listening. These headphones have a detailed, clear, and powerful sound.
Please note: These electrostatic headphones must be paired with an appropriate headphone energizer (Such as the Stax range of energizers).

STAX SR-009S
SR-009S adopts a diaphragm made of ultra-thin super engineering plastic film. The light mass has realized a high transient characteristic throughout the entire audio spectrum.
The main body was redesigned to further reduce resonance as to provide a consistent sound.
ENCLOSURE:
Aluminum is a metal good for sound and suitable material for audio equipment. It is abundantly used, e.g. at the frame supporting the appearance and sound element, to realize high-quality sound, rigidity and lightweight. Almost every part of the SR-009 is manufactured through precise machine processing.
CABLE:
The high-purity copper developed from the necessity of wiring large-scale integration circuits is also known as high-quality audio cables. High-purity copper wire of 99.9999% (6Nines) purity adopted for the cable is further silver-coated and finished with the most suitable structure to drive the earspeaker.
EARPAD:
The earpad of a new design is carefully made by a craftsman's hand and features both the real leather with good humidity environment and the cushion material with moderate elasticity.
The new earpad enables hours of comfortable listening to music.
ARC (headband):
The arc is equipped with a position adjustment mechanism of 10-step slider and corresponds to the wide range of cranial form with individual difference.
