I personally don't like any of those. Usually with EQ's, turning down the knobs instead of increasing them gives better results ("better" as in less distortion):EQ's for soul music (Click to show)EQ's for symphonic metal (Click to show)EQ's for breakbeat (Click to show)EQ's for progressive house (Click to show)EQ's for folktronica (Click to show)
From what I've just did, it looks like a decrease in bass and "increase" in treble causes most tracks to have a more balanced sound to my ears.
Of course, the EQ varies from track to track depending on how they're recorded and mastered (e.g. for the "progressive house" tracks, I used tracks from Deadmau5; "Some Chords" has a lot of really annoying treble and super-boosted bass compared to "Ghosts 'N' Stuff (ft. Rob Swire)", so you can tell from the EQ's which one is which).
Tracks used were V0 (256 kbps VBR) MP3's accurately ripped from CD's through EAC, no external amping, through my MacBook on iTunes 10 (21).
I should mention that dedicated media players that use a lot of resources greatly improves the audio quality despite it being the same hardware. Audirvana Plus on Mac really makes a difference for the "Some Chords" song. Harsh treble is reduced somewhat and bass impact is improved (using the same MP3).
The M-100's block out some noise, but I've seen that the midrange frequencies are not as blocked out compared to other headphones I tried. In my case it's good since I like to hear what's around me while listening to music.
