The stylus is a wear item, and its normal service life is 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 needle tip. As the radius of curvature of the needle tip increases with use, its ability to track high-frequency signals in the groove diminishes. When audio details decrease, high frequencies become weaker and sound quality becomes increasingly dull, indicating it may be time for replacement. The cantilever is made of high-quality material, enhancing durability and helping maintain consistent sound output.
