Step 3
Check multipoint and wrong-device connection
Earbuds may stay connected to a laptop, tablet, or previous phone instead of the device you are using.
Exact path to follow
- 1Turn Bluetooth off on nearby devices temporarily.
- 2Pair with only one device for the test.
- 3Check the earbud companion app if it has multipoint settings.
- 4Retest audio.
Expected result
The earbuds stay connected to the intended device.
If it worked
Re-enable other devices slowly.
If it did not work
Check contacts and fit.
Step 4
Inspect charging contacts and case seating
If one earbud does not charge, it may drop out or never enter pairing mode.
Exact path to follow
- 1Look for debris on earbud and case contacts.
- 2Wipe gently with a dry soft cloth.
- 3Confirm each earbud seats in the case.
- 4Avoid liquids unless the maker specifically says otherwise.
Expected result
Both earbuds charge and power on.
If it worked
Pair again.
If it did not work
Check device-specific reset instructions from the manufacturer.
Step 5
Test another device
Testing another phone or PC separates earbud failure from device settings.
Exact path to follow
- 1Pair earbuds to another phone or PC.
- 2Play audio for a few minutes.
- 3Test microphone if needed.
- 4Note whether the issue follows the earbuds.
Expected result
You know whether the earbuds or original device are the issue.
If it worked
Fix the original device's Bluetooth settings.
If it did not work
The earbuds or case may need service.
Advanced checks
Use only after the safe path
Step 6
Use manufacturer reset instructions
Earbud reset steps vary widely, so guessing can fail or trigger the wrong mode.
Exact path to follow
- 1Find the official manual for the exact model.
- 2Follow the reset steps exactly.
- 3Forget old pairing on the phone or PC.
- 4Pair again.
Expected result
The earbuds rebuild pairing state.
If it worked
Stop.
If it did not work
Consider service or replacement after backup of settings if applicable.

Stop for battery or charging-case warning signs

- Stop if the case overheats.

- Do not keep pairing while earbuds are low battery.
When to ask a technician
- One earbud never charges.
- The case is swollen, hot, or smells unusual.
- The earbuds fail on every device after official reset.

Why does one earbud connect but not the other?
Often one earbud did not charge, the pair state is stale, or the model needs its official reset sequence.
