Stax SR009 Headphones - Over/On Ear Design and Build: The SR-009 features an open-back design, which is typical for electrostatic headphones to offer a broader soundstage. It has a lightweight aluminium enclosure, contributing to both rigidity and sound quality. The headphones come with hand-crafted lamb leather earpads for comfort during extended listening sessions. The headband has a 10-click slider mechanism for optimal fit. Sound Element: The SR-009 utilises a push-pull electrostatic circular sound element.

Is A$4,000 worth paying for this, or is it drifting above the sweet spot? Against your AUD comps, it’s ambitious: the ask sits above the 75th percentile of A$3,624 and well over the median of A$3,230, so I’d want either exceptional condition or extras to justify it.
That said, this is one of Stax’s most admired electrostatics, known for its speed, detail, and effortless resolution, so a clean example can still be a rewarding buy if you’ve been waiting. The upside here is mainly scarcity and condition: if it’s genuinely well cared for, with pads, cable, and packaging intact, the premium is easier to swallow; if not, the gap to the market is hard to ignore.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Stax traces its origins to 1938 in Tokyo, Japan, when Naotake Hayashi founded Showa Kouon Co., Ltd. in Chiyoda-ku. Initially focused on wax disc recording, metal master production, and audio equipment for film soundtracks, the company evolved through the postwar era. In 1950, it launched its first high-frequency condenser microphone, adopted by NHK, and renamed itself STAX Co., Ltd. in 1963, honoring its pioneering Stax-1 mic. A brief suspension in 1995 due to economic pressures gave way to revival, preserving its legacy under family leadership.
The brand specializes in electrostatic headphones, known as "EARSPEAKERS," debuting with the world-first SR-1 in 1960. This innovation spawned enduring lines like the SR series, produced for decades with incremental refinements for superior resolution and staging. Stax complements these with dedicated electrostatic amplifiers and select accessories, eschewing conventional speakers, turntables, DACs, or cables to hone its transducer expertise.
Stax commands a niche high-end position among audiophiles and professionals, revered for unmatched transparency and fidelity that rivals cost-no-object loudspeakers. Its 85-year heritage cements it as a boutique icon in electrostatic technology, far from mass-market fare, appealing to discerning buyers seeking pinnacle sonic transduction.
