Those who have listened to it and I really mean LISTENED or better: those who have them, do you think that you feel something lacking there... please can all those who listened to them answer... no graphs arguments please.
IS THERE REALLY SOMETHING LACKING IN VOICES (female), TIMBRES, GUITARS, CYMBALS?
I think that the real question is that.... is something lacking?
Why can't we also speak this language instead?
Apparently nobody bothers to read my description boxes on my YouTube channel. For what it's worth Sly, I've copied and pasted my final impressions from my channel. I've also recently submitted a tweaked version of these findings to CYMBACAVUM and it should be up in a few days, hopefully. I like the SM64 but I don't think it's a giant killer. Even so, right now it's probably the most used IEM I have in my collection. Seriously, all you guys from the look at the graphs crowd and the I trust my ears crowd should all take a step back from the keyboard and chill for a day or two and stop arguing. You're all doing a disservice to both your camps by arguing non stop on the thread. At this rate it's only a matter of time before someone says the wrong thing and someone else blows up and the thread gets locked. A lot of people on head-fi don't like seeing that happen and are getting rather tired of seeing it repeatedly happen. As it stands right now most people who watch this thread are probably not even bothering to read most of your posts because you're all mostly arguing for the sake or arguing. You guys have to learn to accept no matter how much you argue there's people who will never agree with you no matter what you say. Sometimes it's best just to say oh well and walk away.
Just my two cents.

For starters, while most other pieces of kit are manufactured in China Earsonics decided to keep manufacturing in their own backyard which happens to be France. Although meant for mobile use these IEM's are not low impedance earphones but instead boast a high impedance value of a whopping 98 ohms and a sensitivity value of 122 dB/mW, more on that in a minute. Under the hood we have a triple driver setup with something called a HQ 3 way crossover with impedance corrector which is a crossover design patented by EarSonics.
With the tidbits and specs out of the way it's time to get to the most important part, the sonics. First off, I wouldn't class the SM64 as a sound engineers monitor but instead I class it more along the lines as a very capable fun headphone. What that means is these little babies are rated low on being neutral and instead are rated high on sounding fun. The bass is slightly elevated and sounds lush and full. Even so, the lows do not sound muddy and are textured and detail is quite good with very little bleed into the lower mids. Mid and sub bass rumble is very satisfying and the lows can hit quite hard when called upon.
The mids are very forward, mid centric would be a proper description. Like the lows the mids also sound full and lush and electric guitars have a very nice crunch behind them. Detail retrieval, I would rate as good although I wouldn't mind seeing a little more micro detail present in the sigs mids on some songs. Overall tonality for guitars, flutes, violins and piano is also very good and sounds very natural and effortless. Vocals, especially female vocals, also sound natural and these IEM's do quite well with vocal driven music.
The highs are smooth and extend very well giving the overall sig a sense of added space within it's soundstage. They sound clean and clear and display no grain in the upper registers. Transition between the upper mids and lower highs is good and sibilance seems very well controlled leading me to think there's probably a dip somewhere along the 4 to 5000 khz region of the signature. Although highs extend well and sound clean and clear they are not overly boosted. End result, no fatigue during long listening sessions.
Soundstage, the sig sounds wide and tall with acceptable depth giving the listener a out of head listening experience. Although acceptable I still wouldn't mind seeing a little more added depth and layering added into the equation. Even so, the SM64 still pulls off a very satisfying 3D like audio sound. Instrument separation is very good with good space between instruments and I can pinpoint instruments acceptably well within the soundstage.
As mentioned before the SM64 is not a overly sensitive low impedance earphone. The good news, although it's impedance value is 98 ohms it can still be driven to acceptably loud levels on an MP3 player. The bad news, in my experience, it sounded quite sloppy out of my iPod and iPhone. This IEM benefits from amping and is happier when it has a quality mobile amp behind it and will scale up very nicely. Throw in a quality mobile DAC such as the CLAS-db and it's really happy.
although the SM6 isn't an audiophile earphone it is an incredibly fun and involving little IEM. It has a very liquid like smooth sound signature that's very tastefully done. It's very much a genre master that will handle various kinds of music quite well and will make you want to tap your toes every time you have your favorite tunes playing. It's a definite must have IEM for those in the hobby who like to dance around on the fun side of the fence.
