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