Stax SR-007

POWERFUL SOUND WITH UTMOST DELICACY
The rationale in the development of the new SR-007 Earspeaker was to provide deep powerful sound previously unobtainable in Earspeakers. STAX engineers developed a unique new electrode structure. Visible through the outer case, gold plated on the outer edge this new electrode has less holes than conventional STAX Earspeakers and thus provides an increased diaphragm vibration area allowing for rich and powerful sound yet retaining all the delicacy STAX is famous for.
 
RIGID METAL HOUSING
To maintain clear distortion-free sound it is most important that nothing other than the diaphragm should vibrate. Within the STAX SR-007 the sound element is encased in a thick insulated resin case firmly fixed to the rigid body. The results are nothing short of spectacular.
 
NEW FULLY ADJUSTABLE EARPADS
Utmost comfort for maximum enjoyment of your STAX SR-007 is provided with earpads that are fully adjustable to the shape of your head.

Stax 4070 Closed- Back Type Earspeaker

Special Feature
STAX, the pioneers of the world's first open-air electrostatic type headphone combines over 40 years of experience and new technology to create the 4070 earspeaker, the world's first enclosure electrostatic type headphone.
The 4070's employ an original "bass-reflex like" ventilation air structure, which results in open-air sound quality while eliminating outside noise, thus making a new type of ear speaker.
The high quality sound of electrostatic type music listening can now be obtained even in loud environments. Before, monitoring live recording was difficult. Now, monitoring with the highest form of reproduction is possible without the interference of outside noise.

STAX electrostatic headphones use neither magnets nor coils like ordinary (dynamic) headphones, instead an electrostatic field reproduces sound.

Two parallel-arranged fixed electrodes, which receives the music signal and super thin diaphragms which receives 580V of dc voltage create an electrostatic field that drives the diaphragm. By this principal, the nature of the sound is detailed, sincere, and a reproduction of all nuances.

Stax SR-404 ( Signature )

■Revolutionary new diaphragm of only 1.35 micron in thickness
The Stax SR-404 Signature utilizes a new super thin diaphragm of only 1.35 micron in thickness. This unique diaphragm has only been made possible by a revolutionary new material with a molecular structure previously unavailable. The improvement in sound quality and retrieval of inner detail is simply stunning. The Stax SR-404 comes complete with a low capacitance wide format PC-OCC cable for connection to the SRM-006t Driver Unit.
