For some reason, whenever I have a new headphone my go to tracks tend to be Dire Straits. They sound great out of the Fidelio-Yo-Yo. Perhaps tilted a bit toward the midbass, but, to my midfi ears that's a forgivable and conscious design decision. Some grain up top, as mentioned by Tyll. But smooth and lots of fun. One of those headphones whose flaws are mostly guilty pleasures (nice bass, plenty of mids) and the sins are mostly of omission (e.g., not the last word in detail, soundstage is pretty limited). I think some of you will think the bass a bit too much. There's definitely some thump there. But the mids are very nice and the treble, while slightly grainy, stings in the right places.
