Airpods not connected to the Mac issue

Hi all. I closed my Mac, put the airpods in their case, that was that. I just opened it and put one in my ear then opened the laptop. No sound, but when I click connect, nothing. I also thinking it was my fault, took them out, closed the lid, then opened computer first. Nope. So has anyone else had this? can it be fixed without repairing them? I mean making the bluetooth find it again. haha.
