Maintenance and Care
To ensure the longevity and optimal performance of your earbuds, follow these care guidelines:
- Cleaning: Gently wipe the earbuds and cable with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Storage: When not in use, store your earbuds in a clean, dry place, preferably in a small pouch to prevent tangling and damage to the cable or plug.
