Troubleshooting
If you encounter any issues with your OnePlus Nord Buds 3 Pro, refer to the following common solutions:
- Earbuds not pairing: Ensure both earbuds are in the charging case, open the lid, and press the function button for a few seconds until the indicator light flashes white. Check your device's Bluetooth settings and try reconnecting.
- No sound from one earbud: Place both earbuds back into the charging case, close the lid, wait a few seconds, then open it again. This often re-syncs them.
