I don't listen at high volume and my hearing is quite excellent. I'm guessing that there's something about your ear canal that causes a really good seal (maybe wet ears), or maybe something about my ear canal that I don't get these perfect air-tight bass-thumping seals. FWIW I don't force in-ears deeply into my ear canal, because that's uncomfortable as heck (and tends to make the bass way to boomy and overpronounced in my experience). I only stick the soft rubber part in.
