I thought so too but remembered yesterday I was working at an office they were putting back together after remodeling, and noticed they were playing music off an iPhone and it was surprisingly loud.

That's a good thing. You don't remember guys walking down the street, or getting on the subway, carrying a boom box on their shoulder, loudly blasting distorted music you don't care to hear.

Now they just pump it directly into their ears. Let them destroy their own hearing, not everyone else's. They make Bluetooth speakers if you need to broadcast your music to a group.
