5.1 Cleaning
- Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth.
- Remove ear tips and clean them with mild soap and water. Ensure they are completely dry before reattaching.
- Gently clean the charging contacts on both the earbuds and inside the case with a dry cotton swab to ensure proper charging.

- When not in use, store the earbuds in their charging case to protect them and keep them charged.

5.3 Water Resistance (IP7)
The earbuds are IP7 waterproof, meaning they are protected against immersion in water up to 1 meter for up to 30 minutes. This makes them resistant to sweat and rain. However, they are not designed for swimming or showering. Do not intentionally submerge them in water. Ensure the earbuds are dry before placing them back into the charging case to prevent damage.
