This STAX Earspeaker revives the legendary SR‑009 with enhanced design and accessibility. Featuring the innovative MLER (Multi‑Layer Electrode) technology—originated from the 2011 SR‑009—this model delivers exceptionally flat response, low resonance, and superb sound wave transmission. Its detachable, replaceable cable improves usability, maintenance, and future upgrade options. The new lightweight injection‑molded unit case reduces weight, while the 10‑step adjustable headpad ensures a comfortable fit for all head shapes. Redesigned with a refined body color and improved materials, the SR‑009D makes the renowned high‑end STAX sound experience more attainable than ever.
