I can only afford 1 right now though I'd like to get both. Which one sounds better ultimately? I realize that they're completely different styles and portability has no bearing on the decision. I liked my q460's for jazz, electr, dj...but they were lacking in the "rock" department. I prefer my PortaPro's for rock by far. Just wonder which sounds better for "cross-genre" listening? Good "do it all" phones.
