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 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 o details decrease, treble response deteriorates and sound becomes duller, indicating it may be time for replacement. The stylus body is made of high-quality material that enhances durability and helps maintain consistent o performance.
