The stylus is a consumable product with a normal service life of approximately 300-400 hours. Damage caused by improper handling, excessive tracking force, low-quality records, or 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 groove diminishes. When audio details decrease, high frequencies become less clear and sound quality becomes duller, indicating it may be time to replace the stylus. The stylus cantilever is made of high-quality material, enhancing durability and helping maintain consistent sound output.
