- Cleaning: Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth. Gently remove any earwax or debris from the eartips and speaker mesh using a small, soft brush or cotton swab.
- Storage: When not in use, store the earbuds in their charging case to protect them and keep them charged.
- Temperature: Avoid exposing the earbuds to extreme temperatures (hot or cold) or direct sunlight for extended periods.
