Follow these checks in Audio Fix →When this guide applies
USB-C charging and seating; no reset, port tools or cleaning chemicals.
Connection scope: Bluetooth. Symptom: My device or case won’t charge.
This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.
If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
Checks and possible outcomes
Start at check-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
check-0
Are the case and cable dry and undamaged?
Visible damage or abnormal heat needs support, not repeated charging attempts.
Look for: Confirm the stated observation; do not infer an unavailable detail.
- If Yes / this check is completed → Use a USB-C charging connection
- If No / the check cannot be completed → Keep the last observation for support
- If I do not know / cannot check → An observation is still unknown

check-1
Use a USB-C charging connection
Use a suitable USB-C cable and powered plug rather than a wireless charger for this comparison.
Look for: Perform only this check, then choose whether it could be completed.
- If Yes / this check is completed → Seat both earbuds firmly
- If No / the check cannot be completed → Keep the last observation for support
- If I do not know / cannot check → An observation is still unknown

check-2
Seat both earbuds firmly
Place each in its matching slot and watch whether the case light responds.
Look for: Perform only this check, then choose whether it could be completed.
- If Yes / this check is completed → Do the case lights show a charging progression or full state?
- If No / the check cannot be completed → Keep the last observation for support
- If I do not know / cannot check → An observation is still unknown

check-3
Do the case lights show a charging progression or full state?
The documented full state is all three lights. Lights can turn off after appearing with USB connected; the case button shows them again. A stale app percentage alone is not proof of failed charging.
Look for: Confirm the stated observation; do not infer an unavailable detail.
