About Stax SR-L700 MK2 Headphones
The STAX SR-L700 MK 2 Earspeakers offer a listening experience well beyond that of conventional headphones and really do need to be heard to be believed. The first SR-Lambda series was introduced in 1979 and it has further developed into a new-generation SR-Lambda with its newly designed enclosure - the new SR-L700 MK 2 advanced Lambda series Earspeaker! The MK 2 now features a removable headphone cable as well as an upgraded & strengthened aluminium head band assembly.
Top Quality Sound Element: The SR-009 hand selected thin-film diaphragm as well as fixed electrodes machined through three-layer stainless etching using heat diffusion has been employed for the SR-L700 MK2 sound element. Thus, rich deep bass response, delicate high frequency and soothing mid-range has been achieved in a balanced sound.
10-Click Type Headband Assembly: The headband (ARC) assembly of the SR-L700 is equipped with 10-click slider mechanism for head pad height adjustment adopted from the SR-009. Once adjusted, the slider always maintains its optimal position to make readjustment unnecessary. This enables you to enjoy hours of pleasant music listening with utmost comfort.
New Low-Capacitance Wide Hybrid Cable: 6NCu high purity 99.99999% copper wires are employed for the core wires, and six silver plated high purity 99.9999% copper wires are used for the perimeter. The whole cable uses the conventional wide format parallel structure to lower the capacitance between each wires and finished with the most suitable structure to drive the earspeaker. This cable is now detachable for added convenience.
High-Quality Genuine Lamb Leather Earpads: The high-quality, hand crafted, flexible genuine leather ear pad contributes not only to improve the wear feeling, but also to enhance the "freshness of sound" and "the grace of sound." You can listen for hours in absolute comfort.
Why Electrostatic Headphones?
Electrostatic headphones operate on a different principle than conventional "dynamic" or "moving coil" designs. In a conventional headphones there is a coil of wire inside a magnet, generally glued to a stiff cone or dome that's held in place with a springy suspension. This makes in more difficult to re-create detail in playback due to mass. Or to put simply there are more heavy moving parts.
Pioneered by Stax in 1959 – an electrostatic design works by placing a static (non-moving) electric charge on a film that floats between two perforated metal plates. When audio voltages are applied across the plates, static cling and repulsion causes the entire film to move by itself. This film is so thin, it effectively weighs less than the air around it, and has no resonances or energy storage which leads to distortion inherent in moving coil speakers.
These factors are one of many reasons why Stax electrostatic Headphones sound so much better than conventional designs. During play back the listener is experiencing minimal interference from the headphone speaker itself, in turn bringing you that much closer to the original artist's performance.
