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 surfaces 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 record groove diminishes. When audio details decrease, high frequencies become weaker, and sound quality becomes increasingly dull, it may be time to replace the stylus. The stylus cantilever is made of high-quality material, enhancing rigidity and helping maintain consistent sound output. Output voltage: 4.2 mV. Frequency response: 20 Hz – 20 kHz. Channel balance: 1.5 dB. Stylus type: Highly polished 0.0006 inch conical diamond. Stylus construction: Bonded round shank. Color: White. Material: Plastic. Package contents: 1 × Turntable Stylus.
