The stylus is a consumable product with a normal service life of approximately 300400 hours. Aside from damage caused by improper handling, excessive tracking force, low-quality records, or unstable turntables, the lifespan of the needle tip may be reduced. 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 deteriorates and sound becomes increasingly dull, indicating it may be time for replacement. The stylus body is made of high-quality material, enhancing durability and helping maintain consistent sound output.
