ahhh ok.
i think it looks alright actually, but yeah different strokes an all that.

OMG, that's the flattest graph I've ever seen of a pair of headphones/IEMs!!!!! Are the EM3's frequency response really that flat?
Wish I've seen this before I got my 18 Pro. 

First, here is the freq graph, but dont draw conclusions from it, this graph doesnt show the harmonics, which IMO are the magic of EarSonics:
You have the EM3pros's dont worry. One bore is for the double bass armatures and the other is for the mid-high armatures. I had exactly the same experience that you describe. Our ears are not accustomed to the harmonics at the high freqs that the EM3pro renders (especially coming from the etys), call it burn-in but in around 150-200 hours of play you will start hearing the best musical reproduction youve ever heard, you will hear more details than with the er4's thats what happened to me.
Just relax and play them, they will bloom! this is the experience of almost everyone that has changed to earsonics...
The reason for having more drivers (JH 16 & UE 18) is because they are designed for pro musicians who needed more headroom in their customs so they won't get distortion if they are heavily driven. So in theory, they don't actually improve the sound quality.

^^^ ahhh just as i thought,... they just make it louder.
bump for more people to read this.
and yes they sound as flat as that graph looks.
I want to see an SM3 graph compared alongside that EM3Pro. That would certainly answer some questions for me.
Neither JH or UE were hiding that fact, they did mention that in their descriptions of the JH 16 and UE 18, and that's why they didn't cost a lot more than the models below them with less drivers, and they are exactly as what they claimed they are.
If the EM3 Pros are really that flat, I think I'm very interested in them, so one can just order them through their website?
true, i'm relatively new to this audiophile stuff but i never understood how a clearly stated statement like " more headroom" translated into better sound quality for the average listener.
and yeah either through their website or email them and you'll probably get Franck Lopez himself or his very able assistan Priscille, both of which are a pleasure to deal with.
they're flat but syrupy.
I don't think more headroom is that useful for audiophiles, it's just the safety zone the sound signal is in before clipping or distortion happens. It's not going to kill someone if he can hear a little bit of distortion in his speakers or phones, he can just turn it down a little or use a more powerful amp. But if there is a distortion during a recording, it pretty much render it useless.

more headroom is the opposite of what audiophiles would want, which is why these driver wars surprise me.
the louder you go the less precise you hear the signal cos its your own ears reacting to protect themselves.
Technically its not just about more headroom, it lowers distortion regardless of the volume, whether thats audible might be a different matter though 
Hi Guy,
I am curious why you choose the em3 pro and not a custom by acs in England for example?
I also wonder what material are these customs made off (acryl)?
Greetings, Anouk,
em3's + Sound devices USBPre 2 as dac and amp = pure heaven!
so so clean and balanced across the range, its like i got a new set of em3's 
Funny, I was just thinking the same thing with the HiFiMan 601!
awww crap now i gotta find me one of them to test out
