Currently i own a pair of K701's and quite enjoy how they sound with almost any genre of music. I'm trying to get something that i can take to school, but they don't have to be "strictly portable", as long as the E7 will power them enough. i listen to mostly classic rock and a bit of metal.
so far i've considered:
DT 770/250 (not concerned about the portability, i'd even take my K701's out if they were closed)
AKG K271 MKII
my price range is probably going to be around $350(canadian) or under not including shipping. any suggestions or opinions would be great
