I have decided to return my M100s for a couple of reasons.
1) The isolation isn't good enough for travel. My listening volume, when compared to friends, is way below theirs. When I do crank it up to hear the music, I find it clearer, but discomforting.
2) The recessed mids? I actually don't know what it is. But describing it, I would have to say that vocals with these aren't "wowing" me. I know this is vague but I don't know how else to say it. There's just this feeling that maybe there could be a little more detail... I would have to say my music is strongly vocal based, so vocals are a big part of my ideal sound signature. Though I would also like to also hear other parts of the spectrum. V-Moda actually introduced me and hooked me up on some pretty nice bass. I used to not care about it, but now I can actually appreciate good bass. I'm grateful for being part of the M100 preorders, but I finally feel that the headphones signatures are just not for me.
So why am I here?
Well, I was wondering what other possibilities I can go for after returning my M100s. With the extra cash, I can probably go with the range around $400-700. I am thinking about CIEMs as they might provide me with the isolation I need (well mainly because they look cool imo). And I've also heard that because of the differences in ear canals, IEMs can sound different from their equivalent CIEMs. However, as I am only 17 (ish), I have also heard people advising against CIEM because of ear canal growth and saying that it will change shape every year or two. I'm fine with reshelling every 5 years, but with 1-2, I may have to reevaluate my decisions. My final decisions will probably come around Black Friday or possible Christmas sales, so I still have a reasonable amount of time.
Thank you :)
Though I have honestly no experience with Customs, so I can't help suggest anything there, I do have something to say about the fit. I know many people around your age who get fitted for customs with no problems. The growth issue is minimal,and not too many require a reshell. I hear some nail polish applied on the acrylic can be an alternative for reshelling.
