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 operation may reduce the lifespan of the stylus tip. As the tip's radius of curvature increases over time, its ability to track high-frequency signals in the groove diminishes. When o details decrease, treble response degrades and sound becomes duller, indicating it may be time to replace the stylus. The needle bar is made of high-quality material, enhancing durability and helping maintain consistent sound output.
