Hey @bFALSE! Is anything blocking the Galaxy Buds? Try cleaning them to remove any obstruction with a soft toothbrush or a piece of cotton. Also, please make sure that the Galaxy Buds are fully up to date by heading to: Galaxy Wearable app > About earbuds > Update earbuds software > Download and install.
Right, now turn your Bluetooth off, on your mobile device, wait about 20 seconds and then turn it back on. Finally, proceed with a reset of the buds via: Samsung wearable app > About earbuds > Reset. If resetting the Galaxy Buds didn't sort this, then you would need to visit your closest Samsung Support Centre to have them checked by a Samsung engineer.
