I have recently had the v-moda m80s, currently have the q40's and 780s. I listen to primarily electronic music, but when testing headphones I try a wide variety of genres. I run all my stuff out of my pc into my Fiio E11. My very noobish take on it all follows.
V-moda's: Comfy and dead sexy, very quality build. Very portable as well with nice accessories. The sound was extremely good on the mids and highs, this is def the forte of this pair. The bass was detailed, and not overemphasized. For me, I like a bit more of a punchier, impactful sound. (My sennheiser hd-25's are my ideal bass signature).
Q40's: First pair i bought, portability is not really an option here. These give a ridiculous amount of bass quantity, if that is what you desire, get an E11 and buy these. I added the beyer velour pads aftermarket, and I would suggest you do the same if you get these. All the other frequencies are there, yet I found the bass to be boomy and overwhelming.
HFI-780s: Very comfy (for me). Nice looking also. The bass is extremely detailed in this set, and are excellent for the genres you listed. The bass slams when amped. The treble is emphasized, it is a notch below grating. I find the S-logic to be effective, and the soundstage is good for epic drops and trancey buildups.
If you want portability as a main concern, and do not need super bombastic bass, the vmoda's would be my pick. If you want the most bass and dont mind the large size, q40s would be the way i'd go. The 780s are excellent sounding if you dont mind the treble spike, and they look really nice. Hopefully you find this useful......
