5. Maintenance
- Cleaning: Use a soft, dry, lint-free cloth to clean the earbuds and charging case. Do not use abrasive cleaners or solvents.
- Storage: When not in use, store the earbuds in their charging case to protect them and keep them charged. Store in a cool, dry place away from extreme temperatures.
- Water Resistance: The earbuds are waterproof, meaning they can withstand sweat and light splashes. Do not submerge them in water or expose them to heavy rain.
- Battery Care: To prolong battery life, avoid fully discharging the earbuds and charging case frequently. Charge them regularly, even if not in constant use.
6. Troubleshooting
- Earbuds not pairing:

- Earbuds not charging:
- Ensure the charging cable is securely connected to both the case and the power source. Check the LED display on the case for charging indication. Clean the charging contacts on both the earbuds and the case with a dry cloth. Try a different Type-C cable or power adapter.
