Sub bass

I feel like I'm not not missing that much at least as far as the sound is concerned.

But it is true that you don't get like the physical feeling of it (unless you have one of those weird vests, I guess).

Honestly, not a lot of people in rented apartments can hear music that loud to "feel" the bass. If I did my neighbors would literally kill me.

What? Are you saying my headphones lack sub-bass?
