These ears fit over my own ears so well that I kept forgetting they were there.  Sometimes I would remember them and check to make sure they had not fallen off and they never did.  I wore them to multiple Halloween events as an elf-like creature and received compliments.  Wish I had these a few years ago when we went Star Trek  and I was a Vulcan, they go really well with that costume too.  I'm sure I'll find more opportunities to wear these fake ears, maybe a scary goblin next...
