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 SRM-717 Full Range, High Output Driver Unit
quote:
The STAX SRM-717 Driver Unit is a newly designed Solid-State model featuring DC amplifying circuitry. Dual FETS are used in first stage amplification with rugged emitter followers that combine to achieve superb reliability and extremely low impedance. Results are a remarkable improvement in Earspeaker Driving Power.
The SRM-717 has also been designed to produce a constantly stable output voltage of more than 400V in all frequencies up to 100kHz thus ensuring compatibly with all new audio formats including DVD Audio and SACD.
The renowned STAX attention to detail and build quality continues with a non-magnetic chassis and the elimination of coupling capacitors throughout the circuit ensuring a sound as pure and natural as the real thing.
The STAX SRM-717 features a balanced input to fully utilize the newly designed balanced amplifier circuitry. Fidelity is also enhanced by the use of a precision quality 4-gang volume control.
The STAX SRM-717 provides a bypass mode that enables "direct" connection to preamplifiers, passive volume controls or integrated amplifiers and receivers with "pre out' facilities.

Maybe if I win the lottery but if some one is being paid top dollar for accurate ears for mixing and tracking I suppose thay could pay for themselves by really getting the sound like you want it at tracking.
A man is no fool who gives up that which he can not keep to gain that which he can not lose.
