4070

Closed–Back Type Electrostat ic Earspeakers

■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 ear speaker, 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.
