Dangerously small.  Gets stuck in the ear.
The first time I put this in my ear, it turned around sideways and got stuck in my ear canal and I had to use an object to fish the ear plug out of my ear, which was very awkward.<br /><br />I've been using various ear plus for over 20 years without issues, so doubt this was user error.  These ear plugs are far too small for an adult to use safely.
