Currently I own the Westone UM3X (owned W3, E500, UM2). I'm very happy with them, but I'm looking for an IEM with deep and vibrant sub-bass - something like my headphones Sennheiser HD380 Pro.
 
Must have:
 
1. Deep, vibrant sub-bass - the rest of the spectrum can't suffer from the bass. Would like to have such clarity as UM3X.
2. Great isolation
3. No sibilance at all!
4. No custom IEMs.
 
Anything like it out there?

check the SM3 or IE8 or DDM.
later does not isolate much

X10 can have that bass and smooth treble.

Hippo VB with foamies.

Hippo isn't a bit too harsh?
 
What aboit Atrio? No one recommends it anymore?
 
And Monster Turbine Pro series? Not that kind of sub-bass?

Exactly. Don't forget about the Turbine Pro Golds. I have them and LOVE their bass response with bass heavy music. They have more bass than my HD650 or DT880. They're the funnest headphone I own. People hardly ever mention them, it kinda baffles me...

VB isn't harsh when used with foam tips, at least not to my ears.

The UM3X does have a nice low end, but I can see why people would like that along with a different midrange and high end.
 
I'll point you to the Custom 3 as an option that offers a thicker, textured note from a BA like the UM3X.

I've just received a SM3, and compared to the um3x, I'm not very impressed in the bass department, they're about the same.
Need more listening though...

That's interesting. Waiting for further impressions.
