I usually listen to music when I'm surfing the internets.
But even when there are no sounds, my headphones are on! Hah.
Force of habit? I sit down, turn on my monitor, and put on my headphones.
I'm not wearing them now though, because I'm practicing guitar..
50th story Woo!
I bought a pair of wireless headphones a few years ago (Philips SHC8525) and I use them for most of the day. I don't know about the quality but not being attached to the computer feels great. I can easily walk around the house without taking them off, the range is amazing...
