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, high frequencies become less clear and sound quality becomes dull, indicating it may be time to replace the stylus. The stylus is constructed with high-quality materials to enhance durability and maintain consistent sound performance. 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. Only the above package content is included; other items are not part of this package.
