I think the UE700's sound cleaning and have better treble. They run for $149. The Shure SE215 are built more sturdy. I think either of those are going to great buys for you.
Here is one warning on the Shures:
"These have a huge Achilles' heel. I have to admit, these cans are built like tanks but there is a huge flaw in the construction, a wire soldered to the middle pin to where the detachable cable connects in these cans will snap if you spin the can, it will spin the middle pin with it and twist the wire inside the can until it snaps. 99$ down the drain for something like this."
