The stylus is a consumable product with a typical service life of approximately 300-400 hours. Aside from damage resulting from improper handling, excessive tracking force, low-quality records, or unstable turntable surfaces, these factors may reduce the lifespan of the needle tip. As the radius of curvature of the needle tip increases over time, its ability to accurately track high-frequency signals in the record groove diminishes. When o details decrease, high frequencies become less clear and the sound grows increasingly dull, indicating it may be time to replace the stylus. The stylus body is constructed from high-quality materials, enhancing durability and helping maintain consistent sound performance.
