How well do airpods work with the Apple TV box?

I'm looking at getting an apple tv box so I can quietly watch movies late at night using my air pods, but I'm mostly worried about the bluetooth audio delay. Is there a way to sync the image to the audio? And aside from that, is it more or less seamless to go from the pods to the TV speakers as needed? Would I need to re-sync the image every time I swap the audio output?
