Follow these checks in Audio Fix →When this guide applies
Exact Liberty 4 NC with its own case. Reversible seating/contact checks only; no disassembly and no diagnosis of impact damage or a failed battery.
Connection scope: Bluetooth. Symptom: Sound plays from only one side.
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.
What owners have reported
These are public, self-reported experiences. They help explain the order of checks and the limits of a guide. They are not controlled tests, proof of a cause, a success rate or a substitute for the manufacturer instructions above.
User-reported Liberty 4 NC left earbud stops responding after a dropped case
A user reports one missing case indicator and one unresponsive earbud after an impact. Replies speculate about internal damage.
How this informs the checks: Offer reversible power/contact observations and a support exit; do not label silence as a pairing fault or tell users to open the case.
Limits: There is no verified repair or diagnosis. Disassembly suggestions from the thread are not endorsed.

Check what blocks case contact
Remove any original protective film and check that the ear tip does not obstruct charging contacts. Ensure the case has power.

Possible result
A required observation is missing
Keep the unknown value rather than selecting a similar model or guessing a menu. Check the linked documentation for the exact device and software. If it still differs, ask manufacturer support; this flow cannot confirm the missing detail.
