I had a pair of these that wore out from use (register for the warranty!) and finally, had to buy them again. Finding earplugs that don't hurt -- ones that fit right from the first, so you don't have to change the tips -- that are unobtrusive, and that take the edge off of my misophonia (selective sound sensitivity) is a big deal. For comparison, I tried Vibes, which I struggled to get to seal in my ear; all the fuss caused an abrasion and a subsequent infection (though thankfully only in my outer ear). I need something flexible like EarDial. Watch that the carrying case doesn't unscrew on you, though!
