Sound not heard from one side
Samsung Galaxy Buds sound not heard from one side: one earbud
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
If only one Galaxy Buds earbud plays, Samsung says to check fit, speaker mesh and sound balance, then couple them again: Buds3 and Buds3 Pro, hold the case Connect button 7 seconds; Buds2 Pro and earlier, hold both earbuds 7 seconds inside the case.
Safety first
Stop and check this first
- Judge which side is silent at a low, comfortable volume, and never raise the volume to make up for a silent side.
- Before resetting the Galaxy Buds make sure both earbuds have at least 15% battery; the reset returns them to default settings.
Safe checks you can perform
- Check fit, ear tips and mesh on the silent side
- Centre the sound balance in the phone settings
- Restart the earbuds inside the charging case
- Couple the two earbuds again for your model
- Update the software or reset from the settings
Leave these tasks to a qualified professional
- Do not attempt this professional task: Recouple and update with both earbuds charged
- Do not attempt this professional task: Refer to a Samsung service centre if one earbud stays silent

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Recouple and update with both earbuds charged
What they doThe technician applies the coupling procedure for your series (Connect button or holding both earbuds), updates the software from the settings, and resets only where the page says so, with enough battery.
They must show youthe case light during the 7 seconds, the software version of both earbuds and sound on both sides at low volume.
In writingmodel (SM-R...), final software version and which step restored the sound.
Refer to a Samsung service centre if one earbud stays silent
What they doIf one earbud still will not connect or play after restarting, coupling and updating, the technician advises contacting a Samsung or authorised service centre and does not try to open the earbud.
They must show youthe same earbud failing both in the case test and with the phone while the other works.
In writingaffected side, steps tried, software version and the reference of the service contacted.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Check fit, ear tips and mesh on the silent side
- Who:
- you, holding both earbuds before changing any setting.
- How:
- confirm both are worn correctly, that the tips on each side are the same size, and that the speaker mesh of the silent earbud has no earwax; run the test at a low volume.
- Result that matters:
- rule out a physical fit or debris problem before restarting anything.
- If sound returns after reseating or visible debris is cleared:
- fit was the issue.
- If one side is still silent:
- check the sound balance next.
- Evidence to keep:
- photo of both ear tips and of the mesh on the affected earbud.

Centre the sound balance in the phone settings
- Who:
- you, with the Galaxy Buds already connected to the phone.
- How:
- open Settings, Accessibility, Hearing enhancements and move the Left/right sound balance slider to the middle; remember this setting is not applied during calls.
- Result that matters:
- see whether audio was only tilted to one side by software.
- If both sides play once the slider is centred:
- it was the balance.
- If the slider was already centred and a side stays silent:
- restart the earbuds in the case.
- Evidence to keep:
- screenshot of Hearing enhancements with the slider centred.

Restart the earbuds inside the charging case
- Who:
- you, using a case with enough battery.
- How:
- put each earbud into its own slot, close the case and take them out after 7 seconds or more; if the case battery is low, connect it to the charger first.
- Result that matters:
- force both earbuds to reconnect to the phone.
- If both show as connected and play:
- the connection had stalled halfway.
- If the phone still sees a single earbud:
- couple them again for your model.
- Evidence to keep:
- screenshot of the Galaxy Wearable app or settings showing the connection state.

Couple the two earbuds again for your model
- Who:
- you, with both earbuds seated in the correct slots of the case.
- How:
- for Buds3, Buds3 Pro or Buds3 FE open the case and hold the Connect button on the bottom for 7 seconds; for Buds2 Pro, Buds2, Buds FE and earlier hold both earbuds together for 7 seconds inside the case until the light flashes and goes out.
- Result that matters:
- rebuild the link between the two earbuds as Samsung describes.
- If the light flashes then turns off and the second earbud plays again:
- coupling restored.
- If the light keeps flashing red:
- remove both earbuds, reseat them and repeat the 7 seconds.
- Evidence to keep:
- video of the case light during coupling and the exact model.

Update the software or reset from the settings
- Who:
- you, with both earbuds at 15% battery or more.
- How:
- in Settings tap your Galaxy Buds and use Earbuds software update, or Manage connections then Reset, depending on your One UI version; during an update the earbuds disconnect from the phone.
- Result that matters:
- leave both earbuds on the same software version or on default settings.
- If both play after the update or reset:
- it was a version or settings mismatch.
- If one earbud still stays silent with both charged:
- move on to the referral step.
- Evidence to keep:
- screenshot of the earbuds software version before and after.

What it means
Samsung's support page on what to do when sound is not heard from one side of the Galaxy Buds series says the cause can be earbud fit, debris on the speaker mesh, sound balance settings or a temporary connection problem between the two earbuds. It covers models from Galaxy Buds+ to Buds4 Pro and the steps differ by model. Sound from a single side does not prove an earbud is faulty on its own.
