Okay, my final thought on the Westone UM2, what I have appraised of them:
First off, here's my collection of what are considered by me to be "high end":
Shure SE530
Ultimate Ears Triple fi-10 Pro
Klipsch Image X10
Sleek Audio SA6
Etymotic ER4P
And this is the rest of the ones I really dig:
Denon AH-C751
Ultimate Ears Super fi-5 v2
Ultimate Ears Super fi-4
Ultimate Ears Super fi-3
Etymotic HF2
Klipsch Custom-2
Klipsch Custom-1
JBL Reference 220
Now that those canalphones are listed, I'll continue with this statement.
This is the sound I've been looking for. Of all of the canalphones I've purchased to date, these UM2 are finally what I ever expected to hear from a high end canalphone. These are the ones with the dynamic of sound I thought the others would have. The richness and quality of sound is deep and encompassing. It's so very easy to hear the quality of sound in these particular canalphones. It's like a singer who sings a very moving and emotional song well and another who sings the same moving and emotional song with heart. These represent the song sung with heart. They reach way down inside and bring forth music that reaches in and grabs at your heart.
I don't know how to describe it any other way. These are what I have been expecting all along from all the other high dollar, high end acquisitions. The Clarity of sound is actual and not just a sales ploy. Under the cover of the retail package it declares, "Pure Clarity". On the back of the package it says, "Undeniable Range" These claims are fact, from my perspective.
I have never heard a canalphone with such clarity and perfection of audio output before these UM2. The 3 driver this and that of the other high enders claim a lot about them and from a naive perspective, they live up to the claims. But from a person who has heard the true sound of audio perfection...as close so far as I've come...those others are just imitations of the real.
When I hear of multiple drivers in a canalphone I envision being able to hear outstanding separation of instruments, voices and a sound stage that really puts out a whole stage of band members doing their thing. I have heard a lot of goodness in the others but these UM2s really do provide that separation, that quality of genuine soundstage I have been expecting from these other canalphones. It's as though these UM2 have real and genuine engineering in their construction, in the programming of their crossovers and in the build of the drivers. It's like people stayed up late and put in that last bit of strenuous effort to really make something that is real and does what all the others claim they do.
Threse UM2 are the real deal. They are the best there is and there is nothing that matches them in the universal canalphone world. I believe the Shure SE530s come close but they fall short in a few areas. They don't have that deep impact of the midrange, that clarity of overall sound, that amazing instrumental separation that these UM2s have. What Westone has done with two drivers leaves questions about why the others, who use three drivers, can't even match this level of quality.
My goodness! If Westone has done this with a two-driver phone, I can't imagine the awesomeness of their future three-driver phones.
Take it for what you will but that is what I see and hear and feel about these amazing products from Westone. I CANNOT wait to sample the UM3, or Westone 3, as I have heard they will be labeled.
Thank you for your patience in this review. I wanted to make absolutely certain I wasn't having some kind of "good day" or other before posting my findings on these UM2. Sometimes that can happen to me. One day I will find a product just perfect. The next day, not so perfect. But these have stood the test of a few days time and are still as good as I felt.
