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.
Finally a portable solution for driving Stax headphones! The SRM-D10 delivers a surprising punch for its’ diminutive size, driving the modern Stax headphone lineup to reasonably high listening levels in typical conditions. With a 3.5-4.5 hour battery life, and the open nature of Stax headphones, it makes for more of a trans-portable rig, but for those who want to enjoy their electrostatic headphones when they travel, there is nothing else like it!
