Personally, I've only had crappy-ok headphones

Me too, I've never owned a good pair of headphones.

I see a lot of people with (what appears to be) a good set of headphones on public transport, but It's not my nature to ask strangers their thoughts. I've always wanted a nice set and this thread has some excellent feedback. I'll certainly take a lot of what's said under advisement.
