3. Maintenance
Proper maintenance will prolong the life and appearance of your earphone case.
3.1 Cleaning
- Wipe the exterior aluminum surface with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the matte finish.
- For the interior, use a dry, soft cloth to remove any dust or debris.
3.2 Water Resistance
The case features a water-resistant enclosure. While it offers protection against splashes and light rain, it is not designed for submersion. Ensure the case is properly closed to maintain its water-resistant properties.

4. Troubleshooting
4.1 Difficulty Opening the Case
Due to the secure, water-resistant design, the case may sometimes feel stiff or difficult to open. This is normal and ensures a tight seal.
- Firm Grip: Ensure you have a firm grip on both the top and bottom sections.
- Even Pressure: Apply even, steady pressure when pulling the top section upwards. Avoid twisting.
- Leverage (if necessary): If persistent difficulty occurs, a thin, non-marring object (like a plastic card edge) can be carefully inserted into the seam to gently pry it open. Exercise caution to avoid scratching the case.
