I've been using headphones (a lot) since elementary school, and I was a Club DJ/Turntablist for more than 15 years. For the past decade I've always had a home studio where I make beats and I still listen to music 90% of the time when I'm out and about.
(Yeah, I'm old)
So basically I've been most of my life blasting my ears with music. So unless I go deaf tomorrow, I think I may have bionic ears.
All things taken into consideration, you might be half deaf already. That would explain your disdain for extreme volume.
