STAX SR-009D

The SR-009, the origin of STAX's current high-end models. Equipped with a large circular sound unit featuring innovative fixed electrodes, this model led the high-end headphone culture for a long time. Production had ceased with the arrival of the new flagship model, but now, in response to numerous requests from fans worldwide, it is making a comeback. With changes to the body color, cable material, and unit case, it is now available at a more accessible price than at its original launch.
