There are sleep versions of customs as well. I originally got them for working at home with two kids in lockdown: the combo of Airpods Max, rain noise and custom earplugs is a godsend.

For sleep they weren‘t quite as good as they were too hard for situations when I was laying on that ear. I got new ones from the same molds with the softest silicone they had and these are better.

All in all, it was worth it for me. They clocked in at a third of my Airpods Max and while they don‘t make a big difference in sound to soft silicone, they are much less of a mess to remove and clean. I can pull them our in order to listen to someone and put them right back in.
