I can understand wanting to get your Galaxy buds connected to your device to listen to your audio. While both buds are in the cradle and when you open the lid, does the phone recognize them opening?
Do they appear within the Wearables app?
Also, I would recommend resetting your network settings on the device by following these steps.
Swipe down from the top of the phone to open the notification bar
Tap on the magnifying glass and type in Reset Network Settings
Tap on the option for Reset Network Settings and follow the steps to reset.
Once done, I would recommend restarting your device and try to connect your buds again.
