If your A100 earbuds are not charging in the charging case try the following troubleshooting steps:
1. Ensure that the charging case is charged
2. When connected to a power source/charging cable, do the LED lights on the front of the charging case light up?
3. Try using another power source or another USB-C cable
You can also try using the current charging setup with another device to rule out any fault specific to your charging case.
4. When placed inside the charging case, do the earbuds’ LEDs light up with a white light?
5. Clean your charging case with a suitable cloth or an alcohol cleaning pad
There should be no obstruction in the charging case stopping the ear bud from being properly seated. Be sure to remove any obstruction or debris from the charging case, as well as on and around the charging contacts.
If there is sweat, liquid or obstruction on the charging contacts within the case, corrosion may occur. In this situation, please clean the charging terminal or earphones with a suitable cloth or alcohol cleaning pad before charging. Cotton buds can also be used to get into the charging case to gently clean around the charging pins and remove any obstructions.
6. Perform a factory reset on the A100.
