Full sized headphones

[Dr. Z]

Grados are a love/hate thing. Very unique sound (which I personally don't like) and they on-ear rather than over-ear making them uncomfortable over long periods. They are also open-back, meaning everyone else gets just as much music as you do.

I'd look at the Beyerdynamic DT range if you're after bang-for-buck. Sennheiser are great but can be expensive. I have a pair of very cheap AKGs on loan at the moment and they are fantastic for casual listening although they lack mid-range detail and are a little "muddy" but definitely not fatigueing like the Grados would be (for me).
