The MK2 models have adopted the cable-exchangeable structure as well as the case holder made from aluminum aiming at user-friendliness and wearing comfort when listening to music.
Exchangeable cable structure
The exchangeable cable structure of recent trend for high-quality headphone has been employed. This enables the prospective correspondence to a high-definition cable, and the easy maintenance to sudden disconnection, thus improving the user-friendliness of earspeaker.
To the SR-L500MK2 the parallel 6-strand low-capacity HiFC* wide cable is supplied as an accessory. This copper conductor with very small quantity of titanium added features not only superior transmission characteristic, but also excels in softening effect for easy handling.
Case holder made from aluminum
The change of material has enabled the mechanism design with more high flexibility. In the MK2 models, changing the case holder design from conventional linear style into moderate curve form produces the effect that ear pads fit more naturally on both-sides-of-the-head part. Moreover, the curve form gives high rigidity and prevents from generating unnecessary distortion or twist at the time of wearing, resulting in the great improvement of fit feeling. In an open-air type earspeaker, the degree rise of adhesion at the time of wearing greatly contributes to the improvement of low-frequency reproduction.

About Stax Headphones
Stax produce exclusively electrostatic headphones, or “earspeakers” as they call them, in Japan, since 1938. Stax chose the electrostatic technology for its ability to produce transparent sound, and low weight for comfort/ergonomics, both due to the driver design not employing fixed magnets and moving coils, as opposed to other common headphone driver designs. The minimal weight of the driver ensures a very quick response to the signal, creating a more faithful sound reproduction.
The electrostatic driver creates sound when it is powered by static charge (bias voltage), which reacts to a high voltage signal field created around the driver element by the stators. For this reason, all electrostatic headphones require special amplification to supply the high voltage (DC) bias, and high voltage (AC) audio signal. In the case of modern Stax headphones, that DC bias is 580V. Stax manufactures a number of dedicated amplifiers for their headphones, ranging from a relatively small portable model, SRM-D10, to their flagship SRM-T8000.
The Stax L500 MK2 is the new midrange model in Stax’s L-series lineup, and offers the same removable cable and upgraded headband of its’ cousin the L700 MK2 The L500 Mk2 uses a well-balanced sounding driver, with the open, airy sound you expect from a Stax headphone.
