The silicone mold shifts to hug my ear canal so snugly that I forget I'm wearing them by the time I'm dozing off. Even on my side, there's no pressure point, and they've stayed put through a whole night of tossing.
The waterproof seal is the standout for me—I wore these in the shower and not a drop got in, plus they’re so pliable they mold to my ear without any pressure. Even after a full night’s sleep, they stay put and don’t irritate my skin.
I toss and turn all night, but these stay put thanks to the soft silicone that molds to my ear shape after a few seconds of pressing. They block out my partner's snoring without that pressure feeling I get from foam ones.
