I've been away for awhile, had to sell most of my audio equipment, motorcycle, and all of my headphones to help fund my wife's eye surgeries. She is doing better, but will never be able to see like a normal person, and it has been a struggle to adapt things for her. Sure could have used some headphones all those days at the hospital and at the disability training center, I knew I was in a bad spot when I spent an hour sweating in the car in the florida heat, listening to music in the driveway. So my wife got me some vmoda m100's for our anniversary, so I can listen again. Been glued to my head for about a couple of months now, figured I'd get back on and say hi to everyone and let everyone know that I'm still here, and though it has been months since I've heard my other headphones, vmoda gets my thumbs up for their m100.
Can't give a side by side comparison to what I used to own (ps1000, hd800, hd600, he400, mdrv6, a few others), but I do have to say I'm impressed.
Obviously too much bass for my liking, but its clean and tight, even from my phone which is impressive. I'm going to be probably one of the few to say this, but I don't think the bass overpowers the mids (probably due to the reduced treble), I find that most vocals stand out on their own pretty well, with some exceptions (certain male vocals struggle a bit, but still within acceptable levels). Guitars are present, not as detailed or pronounced as my Grado's, but they have a plucky weight to them that I appreciate. Electronics are amazing sounding, possibly the best I've heard them (not quite as detailed as I remember from the Senns, but certainly some magic to them, especially with the bass, almost makes me wish I had a wider collection of edm. Treble is biggest weakness, rolled off pretty bad off the top, keeps the hisses down, but at a loss of detail and separation. I was one of the ones who, slightly, adjusted down the treble on certain frequencies on the hd800's particularly for certain songs, but I don't have to worry about that with these, I tried boosting certain frequencies, but its just not what the headphone was made for.
Probably best for edm, but found most metal, industrial, grunge exceptional as well. Really lacks the stage for chamber music, but...on the other hand its interesting to hear it with the bass impact, been enjoying just listening to it as a whole.
Classic rock is also interesting, having grown up with my dad listening to classic rock out of the cheapest boombox (think oversized alarm clock), just got used to classic rock being a brash treble mesh of sound. Probably why I usually listened to it with the 325's and the sony's. Now it's like listening to it from a whole new perspective, probably never get used to it, but I'm glad that I tried it. Give acoustic guitar's a nod here because the extra weight from the bass is a nice touch.
I found jazz to be pleasant, overall lack of details, but piano had a pleasant lift, in particular Vince Guaraldi, he always had a way of slamming the keys, softened a bit with these but still present.
Be a long time till I get through my collection, so I may update from time to time, but, pretty much a very good set of headphones, especially if one accounts for their portability. I don't think I would try to amp these unless you are looking for more bass, they are 95 percent right out of my phone. Found them to be very comfortable for portables, it would be unfair to compare them to my others that I have had as they were in no way shape or form portables (an argument could be made for the Sony's as portable) but I have no issues using these as my primary headphone for a while.
