I only wear headphones when I'm out walking, and usually when I walk I listen to classical or jazz (occasionally old prog), so volume isn't very important to me. At home on the weekends, I usually put on concert DVDs and I want concert volume in that case. Since I keep it confined to polite hours, most people don't complain.
Sadly, an old crippled fellow moved in behind me, and he's the sort to start pounding on the wall pretty quickly. I'll probably be moving pretty soon. Since he's old, I suspect he's going to run out the clock in that apartment, and due to the old/crippled qualities, I don't think management will be to accommodating to my concerns over his.
