I've heard that the M-100 is extremely good for music with a bass preference, plus they look really nice. Since your budget seems to be $200 or more since the M-100 cost a bit maybe look at the SRH840, if you try the 440 in a store it will not sound its best as most people would recommend using 840 pads on it. I was able to find a store near my house that had the srh440m, 840, the m50, as well as some other nice headphones and I do not regret buying the 840. You may also want to look at the dt770 as it seems people really like it as well for music with a bass preference.
