Shure SRH440. I've owned and extensively used Sennheiser, Sony, Koss, Audio-Technica AKG, KRK and probably others I've forgotten. For sound quality, the 440s just blow the rest away. In fact, I needed to get some new phones for gaming quite recently, because the Shures' one drawback is that they're heavy and uncomfortable for long stints, and my daughter had effectively taken over the KRKs. I actually used these very recordings to do a quantitative test of the new kids vs. what I already had. I also listened to several different music tracks, and even ran them through a splitter so I could do a true side-by-side comparison. The Shures were simply better than everything else I own, every single time, and they seem to be available for under US$100.
