The stylus is a consumable product with a normal 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 needle tip. As the radius of curvature of the needle tip increases over time, its ability to track high-frequency signals in the groove diminishes. When audio details decrease, treble response degrades and sound becomes dull, indicating it may be time to replace the stylus. The stylus body is made of high-quality material to enhance durability and help maintain consistent sound output.
