Direct answer
A complete failure should be separated into power or eligibility, the external path, and the component itself before any reset. For earbud charging contacts and case, first inspect charge status for each bud, reseat and test the case on known power.
What this covers
- earbud charging contacts and case with this exact failure state
- Diagnosis across earbud contact versus case battery, debris, alignment and cell health
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleRecord whether the feature is absent, disabled, powered but unresponsive, or showing a message. Expected behavior: seat each earbud and gain charge from a powered case.
Isolate the component boundary
ReversibleInspect charge status for each bud, reseat and test the case on known power. Test the simplest supported configuration with unrelated accessories and optional services removed. Boundary to separate: earbud contact versus case battery, debris, alignment and cell health.
Correct only the proven cause
ReversibleClean dry contacts by approved methods or replace the failed bud/case. Restore only the failed prerequisite or path; do not change working layers.
Verify and stop safely
ReversibleRepeat from a cold start and complete one normal use. Stop for swelling, heat, corrosion, liquid or damaged contacts.

Common follow-ups
What should I check first when earbud charging contacts and case has this problem?+
Inspect charge status for each bud, reseat and test the case on known power.
Why not factory-reset immediately?+
The useful boundary is earbud contact versus case battery, debris, alignment and cell health. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
stop for swelling, heat, corrosion, liquid or damaged contacts.
