I wear a luchador mask, I have never had an issues with my ears while wearing it, then I misplaced it for a week and ended up having to drain my ear. So back to the mask full time.
It doesn't move on my head its fairly easy to take on and off with laces up the back, super low profile and it works, I just had the guy that made mine add a little extra padding over the ear and add some vinyl to the outside where my ears are.
only cons is that it gives your opponent more traction, and it is a bit warmer but you get used to that, but I think the intimidation factor makes up fpr it.
