More articulate than I expectedI'm writing this because nearly every review of the ZN I read referenced the M100 from V-moda...but nothing else. It would seem none of the reviews have ever owned Etymotic, Shure, RHA, Sennheiser, UE, etc. So I figured I would write the review I was looking for when debating these headphones. In a word...they're fantastic.So I was looking for a replacement for my Senheiser Momentum buds. Let me start by pointing out my goals/preferences for headphones. I like in-ear design, I listen to mostly electronic music (everything from Depeche Mode to Armin Van Buuren to Trap and D&B), so low end responsiveness and quality is very important to me (much more so than low end quantity...Beats). But clarity and separation are also important. I tend to enjoy the sound signature of Sennheiser almost any other earbuds I've used (though I am aware that Focal, RHA, Fidue and a few others make outstanding earbuds...I just don't have that type of cash). You might say I lean toward a "v-shape" sound preference as opposed to a "neutral/monitor" signature that you might get from Etymotic or Shure. I am using these in my office (so noise, movement or durability aren't much of a factor). Also, I don't like earbuds that wrap the wire around the back of the ear (which rules out most high-end monitors for me). I'd also add that I hadn't really given V-moda much thought...I kinda lumped them in with "mid-priced headphones for teenage bassheads" (I.e Beats, Skull Candy, etc). I'm glad to report I was pleasantly surprised.Fit:Great. Very small, very light. The cord looks to be tough and is pretty tangle free. I don't like the 45 degree jack (I prefer a 90 degree)...but that's not a deal-breaker. It should be noted that it comes with 8 sets of tips (all silicone). But the black tips are much softer than the clear tips. The clear tips caused ear fatigue the first couple times, but switching to the same size of the black tips allowed for a better seal and more comfortable fit.Mic:Have used these on several conference calls (both on my Mac using Skype and on my iPhone 6s) and have been told the sound was very clean.Sound:Lows: Fantastic. They go low, very low. And they are very rich/deep (great for modern Trap and House tracks), but also have plenty of punch to keep up with Flea from the Chili Peppers and Lars from Metallica. The bass is also not overbearing or intrusive (muddying the mids the way Beats do)Mids: Not as warm or inviting to vocal-heavy music as a pair of Shure 315 would be...but like I said, I do tend to prefer a "v-shaped" sound. They were slightly warmer in the mid and upper mid range compared to the Sennheiser.Highs: Sennheiser are known for their great clarity and highs...and this is where (aside from the bass) I think the Zn should get more credit. The Highs from these headphones is great. Very clearly articulated without the sharpness or piercing that I get from the Sennheisers. I didn't even realize how harsh the highs were until I spent a week comparing them. The Highs are just as present with the Zn, but they don't crash at the high end of the spectrum the way my Momentum did. I guess some would call that "sparkle," but after comparing both I found the V-moda to have a much more laid back tone without sacrificing any clarity .Separation and Stage: This is another area where the V-moda really pulled away. The stage seems much larger than the Momentum and the separation much more delineated. Again, I was pretty pleased with the Momentum until I really started scrutinizing them and comparing...guess I didn't know what I was missing.So, there you have it. I think that for $180 you can't do much better, If you have the same preferences as I. If you like over-the-ear wires, or prefer less low end (for more classic rock, jazz, classical) then I'd suggest the Shure SE215 or 315. You might also check out Fidue A71 or A73. If you are willing to shell out $300 I'd recommend looking into the Sennehiser IE80, the RHA t20 or the Shure 425....all are amazing.
