What reviewers said
STAX SR-009S
The STAX SR-009S is a premium electrostatic headphone that refines the original SR-009 formula with a slightly smoother, less bright tuning while retaining exceptional speed, detail, and openness. It offers a wide, precisely imaged soundstage and a very comfortable fit, making it a top-tier choice for critical listening, though it demands high-quality recordings and a dedicated amplifier system to shine. Its performance places it among the very best headphones available, with only the newer X9000 potentially edging it out in some respects.
- Pro:Extremely fast and detailed electrostatic sound
- Pro:Wide, immersive soundstage with precise imaging
- Pro:Comfortable fit despite large earcups
- Con:Very revealing of poor-quality recordings
- Con:Requires specialized electrostatic amplifier, adding cost and complexity
- Con:High price point limits accessibility
