6. Maintenance
6.1 Cleaning
To maintain optimal sound quality and hygiene, regularly clean your earbuds and charging case.
- Earbuds: Gently wipe the earbuds, especially the ear tips and charging contacts, with a soft, dry, lint-free cloth. For stubborn dirt, a slightly damp cloth can be used, but ensure the earbuds are completely dry before placing them back in the charging case. The IPX6 rating means they can withstand powerful water jets, but avoid submerging them for extended periods or using harsh chemicals.
- Charging Case: Wipe the exterior of the charging case with a soft, dry cloth. Use a cotton swab to clean the charging pins inside the case if necessary. Ensure no moisture enters the charging port.
6.2 Storage
When not in use, store your headphones in their charging case to protect them and keep them charged. Store the case in a cool, dry place away from extreme temperatures and direct sunlight.
