IPX7 Waterproof Rating: Both the earbuds and the charging case are IPX7 waterproof, providing protection against sweat, splashes, and rain. This makes them suitable for workouts and outdoor activities.

Maintenance
1. Cleaning
- Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth.
- Do not use abrasive cleaners, alcohol, or chemical solvents.
- Ensure charging contacts on both earbuds and case are clean and free of debris to maintain proper charging.
2. Storage
- Store the earbuds in their charging case when not in use to protect them and keep them charged.
- Avoid storing in extreme temperatures or high humidity.
3. Water Resistance (IPX7)
- The earbuds and charging case are IPX7 waterproof, meaning they can withstand immersion in water up to 1 meter for 30 minutes.
- This rating protects against sweat, rain, and accidental splashes, but they are not designed for swimming or prolonged submersion.
- Ensure the earbuds are dry before placing them back into the charging case to prevent damage to the charging contacts.
Troubleshooting
- Earbuds not pairing: Ensure both earbuds are charged. Place them back in the case, close the lid, then open it again to re-enter pairing mode. Delete "IAII15" from your device's Bluetooth list and try pairing again.
- Only one earbud has sound: Place both earbuds back into the charging case, close the lid, and then open it again. This often resets the connection between the two earbuds. If the issue persists, try re-pairing them with your device.
- Charging issues: Check that the charging cable is securely connected to both the case and the power source. Ensure the charging contacts on the earbuds and inside the case are clean and free of obstructions.
- Poor sound quality: Ensure the earbuds are properly seated in your ears for a good seal. Check your device's volume settings. If the issue persists, try disconnecting and re-pairing the earbuds.
- Touch controls unresponsive: Ensure your fingers are clean and dry. Try restarting the earbuds by placing them in the case and then taking them out again.
