Quick answer
Start with the least destructive check, confirm the device state, and only then change settings. For this problem, the fastest route is usually: Charge both earbuds and clean charging contacts. Check audio balance on the phone or computer. Forget the device and pair again.
Before you start
- Charge both earbuds and clean charging contacts.
- Check audio balance on the phone or computer.
- Forget the device and pair again.
- Reset earbuds according to the case button sequence.
Rule out charging first
One earbud often fails because it never charged. Clean the case contacts and make sure the earbud LED reacts when seated.
Leave both earbuds in the case for at least 20 minutes before pairing again.
Check balance and mono settings
Accessibility audio balance can send sound to one side only. Check the phone, computer, and app player.
Some earbuds enter mono mode if paired separately. Remove both Bluetooth entries and pair from the case again.
Reset the pair
Use the manufacturer reset sequence, usually holding the case button or both earbuds. Then forget the old Bluetooth entry before reconnecting.
If the same side stays silent after reset and charging, the speaker, battery, or contact may be damaged.
Symptom checklist
| What you see | Most likely cause | First safe action |
|---|---|---|
| The device reacts, but the result is wrong | Wrong input, profile, mode, or account state | Confirm the visible setting before resetting anything |
| Nothing reacts at all | Power, cable, port, battery, or button issue | Test with a known good power source or cable |
| The problem comes back after reboot | Saved setting, weak signal, low storage, or failing accessory | Change one variable and write down what changed |
FAQ
- Why are there two Bluetooth names?
- The earbuds may have paired separately. Remove both names and pair them together from the case.
- Can earwax block sound completely?
- Yes. A clogged mesh can make an earbud seem dead. Clean gently according to the manufacturer instructions.
