Maintenance
Proper care ensures the longevity and performance of your Redmi Airdots.
- Cleaning: Use a soft, dry, lint-free cloth to clean the earbuds and charging case. Do not use abrasive cleaners, alcohol, or chemical solvents.
- Water Resistance: The earbuds are IPX4 waterproof, meaning they are resistant to splashing water and sweat. Do not submerge them in water or expose them to heavy rain. Dry them thoroughly if they get wet.
- 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 direct sunlight and extreme temperatures.
- Ear Tips: Regularly check and clean the ear tips to prevent wax buildup, which can affect sound quality. Replace ear tips if they become damaged or worn.
Troubleshooting
If you encounter issues, try these common solutions:
| Problem | Solution |
|---|---|
| Earbuds not pairing with each other. | Place both earbuds back into the charging case. Close the lid, wait a few seconds, then open and take them out again. This often forces them to re-sync. |
| Earbuds not connecting to device. | Ensure Bluetooth is enabled on your device. Forget "Redmi Airdots" in your device's Bluetooth settings and try pairing again. Ensure earbuds are charged. |
| Only one earbud working. | Place both earbuds back in the case, then take them out simultaneously. Check battery levels of both earbuds. |
| Low volume or poor sound quality. | Adjust volume on your device. Ensure ear tips are clean and properly seated in your ear. Try different sized ear tips for a better seal. |
| Earbuds not charging. | Ensure charging contacts on earbuds and inside case are clean and dry. Check USB cable and power adapter. Ensure case has power. |
