The stylus is a consumable product with a normal service life of approximately 300–400 hours. Life expectancy may be reduced due to improper handling, excessive tracking force, use of low-quality records, or unstable turntable conditions. As the stylus tip wears and the radius of curvature increases, its ability to track high-frequency signals diminishes. When o details decrease, treble response degrades and sound becomes duller, indicating it may be time for replacement. The needle bar is made of high-quality material, enhancing durability and ensuring consistent sound performance.
