Yeah, I'm an audiophile, and if you're not crazy into audio a lot of this is probably going to sound weird. Still...

Earphones really are getting better very quickly, and if you look at all of audio, that fact is pretty remarkable.

In speakers, things have peaked a long time ago, no matter what those Bose ads tell you. The Quad ESL-57 speaker was first shown in the mid 50's, and it is STILL considered to be one of the very best speakers ever made. In traditional headphones things haven't moved very quickly either, and Stax SR-Lambda headphones from 1979 sound as good as pretty much any headsets you can find today. The Sennheiser HD800 is touted as the latest and greatest, but the Stax SR-007 Omega 2 from 11 years ago is still better, and so is the 15-year-old SR-Omega, and the 18-year-old Sennheiser HE90 "Orpheus."

Which means that if you have an audio technology that's genuinely getting better, it's an exception to the rule. And the UM3x is a clear improvement on what has been released only a year or so ago.

These earphones have a very clear, detailed sound that's also very fluid. The bass is detailed and well controlled. The midrange is slightly emphasized and very tonally accurate - instruments sound very realistic and vocals sound almost live, if they're recorded well. The highs are slightly recessed (soft) but are also quite extended. Soundstage is smallish, though pretty large for an IEM, and imaging is razor sharp. The drivers are pretty fast, too, and keep up with complex music well. But the best feature of these IEMs is their ability to do texture - strings sound gravelly, brass instruments are, well, brassy and metallic, woodwinds are seductive and ethereal, and vocals are very realistic.

I just received my Westone UM3x's this week and all I can say is, "Wow". I also own the Shure se530's and Ultimate Ear 10's and I really enjoyed both but I couldn't help but note the flaws in both IEM's. It's no news to anyone who's been on this fourm, "se530's do great in the mids, but have recessed ends" or "'s have great hi's and decent mids and lows" etc. Simply put, Each of the two IEM's excelled in one particular area, but had often noted flaws in another area. With the UM3X's, there really is no weak point in it's presentation. This doesn't mean that it can't improve, but there really is no weak point in it's sound. I think the best way to understand this is through numbers, so here's my evaluation:

High - 7.5
Mid - 9.5
Low - 8.5

High - 9.5
Mid - 8
Low - 8

High - 9
Mid - 9
Low - 9

I know that it's solid performance has to do with it's "flat" EQ, which some may initially get turned off by, because when some people think, "flat" EQ, they think boring. But let me tell you, I REALLY, REALLY enjoyed these, and could not help but get into in my music, bobbing my head, air drumming, etc, haha. To me, after hearing these, rather than saying "flat EQ", I would rather explain it as, "Synchronized/Balanced" EQ. All levels perform so well, that not one section of sound overpowers the other.

As far as soundstage, comparing these three IEMs, I say, with confidence, that the UM3x has this one locked down. Again this has to do with its' "flat" EQ.

My audio journey: Sennheiser IE8, then Westone 3, then Westone 3 again, and finally, UM3x.
My setup: Cowon J3 playing all FLAC files - UM3x

I didn't like the Sennheisers because they were so dark. The Westone 3s fixed that problem, but introduced some of their own.
When I first got the W3s, I was floored by their comfort, isolation, durability, design, and of course, sound quality. But my music collection began to slowly drift further towards the electronic side of the spectrum. Of course, with the Westone 3's midbass hump and recessed mids, it's what sounded best on my equipment. But after losing my first pair, I was so close to picking the UM3x, but went for the W3 again because I knew I liked the sound and thought that its "smile curve" sound signature would make it sound better at the low volume levels i listen, because of equal-loudness contours.

But the reviews of the UM3x tantalized me, and whispered into my dreams at night until I couldn't take it any longer. I bought them, and waited for a couple of days, jumping at every UPS truck that drove down my street until they finally arrived. I plugged them in, and loaded up some trance, something I prided the W3 on being able to reproduce particularly well, Markus Schulz' album "Do You Dream?". But wait...there were background vocals on that track? And that subtle string part, where did that come from?

Suddenly, I could hear everything. Everything was there, all the simultaneous musical parts, fleshed out in front of me for me, inviting me to pick out a part and follow it for a while. And that's what I did. I compared the two on the same song, "Moonlight" by Kamelot, and heard the piano like never before. And that's when I realized that the W3s really did have recessed mids.
