Ideal headphones for everyday use?

[Roob]

Hey all,

Just dropping another question which followed from my previous post about file formats for my library and MP3 players, and one user posted the comment that headphones/speakers are (more often than not) the fault behind the limited sound quality, in this case, from my iPod.

I go around A LOT in my day (university, train journey, etc.) and I currently use my Sennheiser HD438's, which are really good; I love the bass feedback from the headphones and think they are fantastic.

But I was wondering what you guys use and whether you could recommend me trying other headphones, which I'm hoping to find in the price range of $150-$250.

So, what headphones do you use?
