Even higher sound quality of music headphones [ST-90-05]! In addition to the engineering plastic film's diaphragm theoretical value 1 Tesla magnetic circuit, it uses Hisago Electric Materials' high-quality oxygen-free copper (OFC: Oxygen-Free Copper) cable. Furthermore, by performing optimal tuning, natural and well-defined sound quality is achieved across the entire range. Just like the ST-90-05, we are particular about domestic production, while maintaining the retro-modern design and high robustness that has been proven for "commercial use."
