The STAX SR-L500 is the midrange model in the L-series, and offers the headband design from the flagship SR-009 and upgraded ear pads from the L300 for comfort. The L500 is well-balanced, with the open, airy sound you expect from a STAX headphone.
Strictly selected thin-film diaphragm as well as tough stainless fixed electrodes has also been employed for the SR-L500. Thus rich deep bass-response, delicate high-frequency and soothing mid-range have been realized in a balanced manner.
The arc assembly of the SR-L500 is equipped with 10-click slider mechanism for head-pad height adjustment. Once adjusted, the slid- er always maintains its optimal position to make its readjustment unnecessary. This enables you to enjoy hours of pleasant listening to music with optimal wear comfort.
High-performance new HiFC cable has been employed for the core wires. The whole cable uses the conventional wide parallel struc- ture to lower the capacitance between each wire strand. This further improves the “freshness of sound”.
The high-quality flexible artificial leather ear pad contributes not only to improve the wear feeling, but also to enhance the “freshness of sound” and “the grace of sound.”

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.
