The HD25-1 II are quite good for their price point. So, given your specified budget, you might want to look into the Ultrasone Pro 750, excellent for EDM, metal and bass emphasized genres. It's a set with a lot of clarity due to their titanium drivers, with present quality bass that's not overpowering nor does it bleed into the rest of the frequency genre, and it's fast enough to handle metal, a genre that benefits from fast transients.
Hmm, I'll look into those. Are they fairly good for mobile use? Also, how do you feel about the AKG k167's I mentioned for my preference?
