6. Maintenance

6.1 Cleaning and Storage

• Regularly clean the earbuds and charging case with a soft, dry cloth.
• Avoid using abrasive materials or harsh chemicals.
• Store the earbuds in their charging case when not in use to protect them and ensure they are charged.
• Keep the device away from extreme temperatures and humidity.

6.2 Waterproofing (IPX5)

The Mibro S1 earbuds are IPX5 waterproof, meaning they can effectively resist water splashes from any direction. This makes them suitable for daily use, including during exercise where they may be exposed to sweat or light rain. However, they are not designed for submersion in water or use during swimming.

6.3 Battery Care

The charging case has a 600mAh battery, providing up to 35 hours of total listening time with the earbuds (5 hours per earbud, plus 6 full charges from the case). The case features a clear LED battery indicator to prevent low battery anxiety and includes various protections like overshoot, temperature, cell PTC, over-power, short-circuit, and voltage stabilization protection.

7. Troubleshooting

• Earbuds not pairing: Ensure both earbuds are in the charging case, then open the lid to activate pairing mode. Check your device's Bluetooth settings and try reconnecting.
• Only one earbud working: Place both earbuds back in the case, close the lid, wait a few seconds, then open it again. This often resets the connection between the two earbuds.
• No sound: Check the volume level on your connected device and ensure the earbuds are properly paired.
• Charging issues: Ensure the charging cable is securely connected to both the case and the power source. Clean the charging contacts on the earbuds and inside the case if necessary.
• Touch controls unresponsive: Ensure your fingers are clean and dry. Try resetting the earbuds by placing them in the case and closing the lid.

8. User Tips

• Initial Check: Upon receiving your earbuds, it's recommended to fully charge them and test all functions to ensure they are working correctly.
• Optimal Fit: The half in-ear design (each earbud weighs only 3.7g) is designed for comfortable long-term wear. Experiment with the positioning in your ear for the best sound and secure fit.
• Battery Management: With a total of 35 hours of battery life (including the charging case), you can enjoy extended listening. Keep an eye on the LED indicators on the charging case to monitor battery levels.
