I'll tell you this much....
I took my C4 to a fellow head-fi member's house. He owns a UERM. Using my C4, he could tell they were better than his UERM.
That isn't to say he was/is going to chuck away his UERM, but he did admit they were better.

Any idea on shipping times and costs to NA? And does the frog design on the faceplates come by default?
Love the colour options on their site, John Deere Green, LOL.
But if there was even a slight section in the sound sig that wasn't completely neutral, would you have any idea where it would be?
Tell me the secret behind that perfect drop.
Tell me it's not a TWFK. ![]()
LFF has a lot of experience here and you can get other's customs to seal by dealing with some pain or a push.
He does like TWFK's more than I do, however.
That's a bit of a joke as I haven't heard every application. Playing with tube length, filter and xover may do wonders I've not yet experienced.

Yes.
I ran a frequency sweep and did hear a tiny section that had a suckout. That said, I can only hear it on sweeps and can't hear it on music...no matter how hard I try. Suck outs are extremely difficult to hear, even by the most experienced mastering engineers and sound engineers.
As for the UERM, I have tried three universal models and one custom that fit in my ear canals.

Yes.

Well, better suck outs than peaks, that's for sure. I haven't heard them, but I hear while the UERMs are pretty neutral, there's some emphasis on treble, which makes me think twice about getting them (then again, the Miracles reportedly have that as well). The C4s sound like an enticing alternative.

Indeed! I swear...unless you run individual tones, you will NEVER hear it.
Of the three universals I heard, none of them sounded EXACTLY alike. They all had a neutral sound signature, yes...but they varied a little. I think that's just the nature of IEM's and our ears.
May I know which section of the FR is the suckout at?
