Galaxy Buds3 Pro: check media balance and the earbud link
Check the Galaxy phone media balance before using the exact Buds3 Pro earbud-link procedure.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Exact Galaxy Buds3 Pro SM-R630 on a Samsung Galaxy phone. The self-coupling branch is limited to the original matched pair with both buds present and charged; replacement/mixed-firmware cases need separate support.
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 Buds3 Pro right side will not connect to a Galaxy S23
An owner describes a right-side connection failure and abnormal left-side volume, with symptoms changing after resets and unpairing.
How this informs the checks: Start with media/balance observations, then the exact model’s documented earbud-link procedure if its conditions hold. Avoid treating a reset as proof of repair.
Limits: The account supplies no controlled repair outcome; firmware, earbud-link and hardware causes are not distinguished.

Does the one-side symptom affect ordinary music or video?
This balance check is for media playback, not a call-only symptom.

- If Yes, ordinary media is affected → Inspect the left/right balance control
- If No, only calls are affected → The media-balance control does not apply during calls

Inspect the left/right balance control
While connected, open Settings > Accessibility > Hearing enhancements. Check Left/right sound balance and move it to the centre if it was shifted. If the path differs, stop.

Possible result
The media-balance control does not apply during calls
Samsung states that left/right sound balance is not applied to calls. A call-only problem needs a call-routing or manufacturer-support check instead of a balance adjustment.
documented limitation
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

A necessary detail is still unknown
Do not replace the unknown detail with a similar model or an assumed setting. Check the linked instructions and your exact device/software. If the required observation remains unavailable, contact the manufacturer.

Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
The check needs a different next step
These observations did not establish a working setup. Read the relevant official instructions or contact manufacturer support with your exact models, software and last observation. No cause or hardware fault is diagnosed.
