• Do not use abrasive cleaners, solvents, or aerosol sprays.
• Gently clean the charging contacts on both the earbuds and the case with a dry cotton swab if necessary.

7. Troubleshooting

If you encounter issues with your INIU I510 Wireless Earbuds, refer to the following common solutions:

• Earbuds not pairing: Ensure both earbuds are charged and out of the case. Turn off Bluetooth on your device, then turn it back on and try pairing again. If issues persist, try resetting the earbuds (refer to the quick start guide for specific reset instructions).
• Only one earbud working: Place both earbuds back into the charging case, close the lid, and then open it again. This often re-syncs them. If not, try re-pairing them with your device.
• No sound: Check the volume level on your connected device. Ensure the earbuds are properly paired and connected.
• Charging issues: Verify that the USB-C cable is securely connected to both the charging case and the power source. Ensure the charging contacts on the earbuds and inside the case are clean and free of debris.
• Uncomfortable fit: The earbuds feature a semi in-ear design. Adjust their position slightly in your ear to find the most comfortable and secure fit.
