... all the flashy tech and noise-cancelling tech in the world is never any substitute for comfortable headphones.
I've got some high quality sennheiser in-ear buds that set me back £90 - the audio quality is outstanding, but after anything more than 30 minutes, they get *Really* uncomfortable. In fact, ear bud phones in general really don't suit me. I use those when I dabble with creating music.
The phones I mentioned in my post above are great, however, I will admit they make my ears uncomfortably hot after a while. Very useful for work when developing audio related stuff, or listening to video tutorials - maybe an hour tops, then I need a break.
The most comfortable phones I've got, for my iPod, are ... once again senheissers ... but are standard old fashioned style over-ear - like the old walkman ones - I can wear them for hours, so they are perfect for listening to my iPod at work.

Yeah, I've got a *lot* of headphones - for different purposes - one set doesn't suit all tasks, least ways, not that I've found yet.
If it's comfort you want, over ear (not covering the ear), light weight phones are the best, but sure, they don't have the best audio quality.
