6. Maintenance
6.1 Cleaning
Regularly clean your earbuds and charging case to maintain optimal performance and hygiene. Use a soft, dry, lint-free cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid getting moisture into any openings.
6.2 Storage

6.3 Water Resistance (IPX7)
The earbuds are rated IPX7 waterproof, meaning they can withstand immersion in water up to 1 meter for 30 minutes. This makes them suitable for workouts and light rain. However, they are not designed for swimming or prolonged submersion. Ensure the earbuds are dry before placing them back into the charging case to prevent damage.
