Maintenance
Cleaning and Care

The IPX6 waterproof rating effectively prevents sweat erosion. The headphone shell adopts a nano plating process, making it fashionable, durable, and easy to clean. Simply wipe gently if stained with sweat to restore its shine.
- Regularly wipe the earbuds and charging case with a soft, dry, lint-free cloth.
- For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals or abrasive materials.
