For comparison the stock sony cushions are 16mm. It really sticks itself to the outlet and doesnt feel loose. I’m guessing my ears are the 10% that AirPods do not fit in ANY way on but I couldn’t make a move without them literally falling out. Vert disappointed in these shoes. Highly recommend getting these bad boys! I have my Bose QC35s if I want to immerse myself. And a simple design that is really nice to look at. I ordered my friend a size 6 and I ordered a size 7 (my actual size). Shoes the shoes run a 1/2 size bigger then expected. They are snug, but not too snug, like how I think performing shoes should be.
