We bought these to use with our 4 year old on the plane. Liked that they folded up, were easy to adjust, and a good fit that stayed on his head. He is pretty sensitive to tight hats and headbands, but he comfortably wore these. They expand large enough that I could put them on to test volume. The fold up was easy for travel. I can't speak to the longevity because we used them only on flights and now they are stored in a closet, but they withstood being shoved into carry ons.
