Ensure that the ear tips are not blocking the charging pins on the earbuds and in the charging case.

When you place the left and right earbuds in the charging case, there will be white LED indicators which confirms the earbuds are properly connected with the charging case. It's important to note that when resetting the earbuds, they should be properly connected to the charging case. If there is a pop-up window to confirm pairing for "soundcore Liberty 4 NC," please select "pair" If you accidentally select "cancel" you need to refresh (turn off and turn on) the Bluetooth of your device and pair the earbuds again.When the battery of the charging case is at 0-20%, the light in the middle of the charging case will turn red for 5 seconds and then go out.

If you are using a Samsung mobile phone, you may need to manually activate the LDAC switch in the Bluetooth settings interface. Take the Fit Test on the soundcore app to check if you're wearing the earbuds in the perfect position. If you cannot adjust the volume on the app, please select "Liberty 4 NC Hands-Free" as output on your computer and adjust the volume. If you still can't connect using the steps above, provide the mobile phone model, app version, screenshots in Step 5, mobile phone system region, and language settings. Replace the ear tips with ones that fit more snugly in your ears and ensure that you are wearing the earbuds in the correct position to create a tight seal.

When the charging case is fully charged, all the white lights will stay on for 5 minutes and then go out.
