The stylus is a consumable product with a normal service life of approximately 300-400 hours. Usage factors such as excessive stylus pressure, poor-quality records, and unstable turntable conditions may reduce its lifespan. As the radius of curvature of the stylus tip increases over time, its ability to track high-frequency signals in the groove diminishes. When audio details decrease, high frequencies become less clear and sound quality becomes duller, indicating the need for replacement. The stylus body is made of high-quality material to enhance durability and help maintain consistent sound output.
