The stylus is a consumable product with a normal service life of approximately 300-400 hours. Life expectancy may be reduced due to improper handling, excessive tracking force, use of low-quality records, or unstable turntable conditions. As the radius of curvature of the stylus tip increases with wear, its ability to track high-frequency signals in the record groove diminishes. When audio details decrease, high frequencies become less clear and sound quality becomes duller, indicating it may be time for replacement. The cantilever is made of high-quality material, providing enhanced rigidity and consistent sound performance.
