We’ve tried out a LOT of different headphones over the years for our kids. For kiddos who love soft headphones, these are so comfy and stay on easily. They’re perfect for toddlers and preschoolers, but lots of elementary kids love them, too (our 9 year old daughter still uses and loves them!).
For older kiddos, we’ve owned both these and these and prefer the latter. They are a bit more sturdy around the folding area and seem to hold up a bit better, but both work well!
For adults, I’m a big fan of my AirPods Pro, and love this case for them.
