Maintenance
Cleaning:
- Regularly clean the earbuds, especially the ear tips and speaker grilles, to prevent wax buildup and maintain sound quality.
- Use a soft, dry cloth to wipe the exterior of the earbuds and cable.
- For ear tips, you may gently remove them and clean with a mild soap solution, then rinse thoroughly and ensure they are completely dry before reattaching.
- Do not use harsh chemicals or abrasive materials.
Storage:
- When not in use, store your earbuds in the provided protective case to prevent tangling and damage.
- Avoid extreme temperatures and humidity.
- Do not wrap the cable too tightly around the earbuds, as this can cause internal wire damage over time.
