These need to be worn with an ear bandit so they dont come out. You warm the silicone between your fingers, place in your outer ear then pull your bandit up and over your ears (the bandit is a headband made of neoprene).
I suffer from recurring ear infections caused by swimming. Since purchasing these I have not had a single one nor do I expect to.
My young son had gromits fitted as a child and could not swim as nothing like this was available then, so pleased something is now available for those budding swimmers
