I've also been looking for something to replace my ipod ear buds. I'll wear them when I'm out in the yard for a good hour or two, and my ears kind of hurt afterwards. Plus, the quality kind of sucks. I'd like to upgrade to something more comfortable, and with better sound, but that doesn't cost a ridiculous amount of money.
Heck, I still haven't replaced my gaming headphones. I'm willing to spend a bit more in this department, but it's so hard to find ones that fit comfortably.
