STAX SR-009S Electrostatic Headphones (Open Box, Wood Carrying Box Has A Crack)

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 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 a 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 a 10-step slider and corresponds to the wide range of cranial form with individual differences.
