Maintenance
To ensure the longevity and optimal performance of your Mpow S42 earphones, follow these maintenance guidelines:

- Storage: Always store the earbuds in their charging case when not in use to protect them from dust, dirt, and physical damage. Store in a cool, dry place away from extreme temperatures.
- Water Resistance: The earphones are IPX6 waterproof, meaning they are resistant to strong jets of water. However, they are not designed for immersion. Do not swim or shower with them, and avoid exposing them to saltwater or other liquids.
