Thanks for the pictures, they are really descriptive!
You're most welcome.
.... the shell itself doesnt stick in all the way.
Just to clarify this a bit more - the CIEM will
always stick out a little bit. That's normal, because of having so many drivers in the earpiece. When I said that the CIEM should sit under the flap of skin (crus of the helix), I only meant the ridge of plastic that I pointed to - with most people's ears, the amount of plastic that fits beneath the flap of skin is approximately 6-8mm, or roughly half the thickness of an average CIEM shell.

Maybe the impression didn't cover there, I don't know.
Some people do have poor impressions, but we all generally try to steer people into getting better ones done, if that happens (e.g.

It is extremely unlikely that the Noble team would have gone ahead and made your CIEMs from substandard impressions.
I don't work for Noble and am not (yet) even a Noble customer, but I know they take fit, finish, and customer satisfaction very seriously. As someone who is merely a fellow CIEM user, I genuinely suspect that your current issue is probably due to not yet being familiar with fully inserting CIEMs. There's a knack to it, which one soon learns, but it can seem strange in the beginning.
Before I proceed further, I need to point out that different areas of a CIEM may have different pressure points for different people, but, broadly-speaking, what follows remains generally-applicable:
You mentioned:
.... the insertion depth doesn't feel as deep as it should be.
the angle of iem goes off
The grip on the canals feel like it's on the mid section and it feels like it "wants" to push the iem out, instead of holding it in. I can't really describe this.
It is absolutely appropriate that new CIEM users be very careful when inserting their CIEMs, because the ear canal is a delicate piece of the anatomy and should be treated with care and respect. However, as I mentioned previously, there is a knack to inserting a CIEM and because there are so many angles and bumps and voids in the ear canal, it's not just the crus of the helix that needs to be successfully 'navigated' when inserting your K10s.
What you described in your above quote suggests to me that you haven't inserted your K10s deep enough within the ear canal, and here's why I'm saying that:
Can you see how this part of the CIEM 'kicks-out'/bulges a bit? Well, until the CIEM is
fully inserted, this part of the CIEM will feel uncomfortable in the middle part of your ear canal,
and it will feel like the CIEM is trying to come out. That bulge on the CIEM that I've circled needs to go
past a certain point in your ear canal, and then it will suddenly feel very comfortable and very secure. When you have successfully accomplished this, you will find that the ridge I described earlier will also fit very easily and snugly behind the 'crus' of your helix. The same thing is also true of the 'kick'/bulge I mentioned in the earlier link (
http://www.head-fi.org/t/684787/noble-audio-the-wizard-returns/1530#post_10176492), where the CIEM has to fit near the 2nd bend of the ear canal. Basically, there are
lots of lumps and bumps, in the middle
and deeper parts of the ear canal, that you need to get the CIEM to slide just
past and then it'll be comfy and secure, but if it's not quite all the way there, then you'll get a rubbish acoustic seal and the CIEM will exert uncomfortable pressure on all those lumps and bumps, and they'll retaliate by trying to 'eject' the CIEM from your ear, at every opportunity!
In summary, although you need to be extremely slow, gentle, and careful, I suggest you take the time to patiently wiggle the CIEM more deeply into your ear than you have yet done. Don't be afraid. Just be slow and careful and you should eventually find that it suddenly clicks into place perfectly. Only learn this when you have the time to sit alone, in a comfortable chair.
Bonus tip:
don't try to learn this whilst you're sitting on a bus! (but sitting on an aeroplane, on the way to Taiwan, should be OK, once you're at cruising altitude )
