Have you had the chance to test a 60003 against the 22955 and check FR and impedance charts?
 
Also Wiring the CI22955 half tap will lower its spl outpout? 

I have a UE CI-60003 and it measured exactly like the 22955 on my Veritas.  But again, any Knowles driver that starts with 6 is pretty much a wild card.  
 
CI at half tap should increase spl if I'm not mistaken...just like a 2389 or ED...

  I am sure Pitor have a few ticks under his sleeve, as dealing with this hobby requires experience as we are all learning along the way...
.
The overall process is almost the same as acrylic no need for uv...you need some AB DREVE biopor silicone material or other similar products from other companies. I think 40 shore is the usual hardness.
There are a few vid on youtube showing the overall process this one for example https://www.youtube.com/watch?v=2WgR3-NgD3E
 
A few things to remember; don't use vented driver unless you make a pocket of air for them while filling the shell after it have been emptied. Silicone mold tend to turn yellow with time and are annoying to insert.
you will need a special lacquer to coat them.
That's all I got for now

Thank you. Stupid question but could you make a mold and the actual CIEM from the same silicone? And can you use nail polish to coat?

Yes i did. We remolded IEMs with 60003 few times.

The biggest difference was that 22955 had first peak around 800Hz while 60003 peaked around 2kHz. It was very low 3-4dB bump. Regular CI also stated to roll off after first peak while 60003 rolled after 4kHz if my memory is correct. I didn't measure impedance, though, just fr, but Rdc is different as far as i remember.
I think i may have one 60003 in the lab, I'll check tomorrow. If so I'll post graphs.

Wiring CI half coil will cut its impedance by two effectively making it louder.

Do you have a "jig", can you measure the 6003 impedance chart on limp (arta impedance software suite) please and post it?
 
I can help you make it, it's very easy.

If you could post graphs of frequency response and impedance that could be awesome! 
Save me from my misery haha. I have been wiring this setup for 2 days trying al kind of configs and and crossovers, although I am pretty sure of the original values...

Ear impression material is not the same as the AB silicone, ear impression have a 20 shore resistance usually. it doesn't have the same flexibility and tear resistance as the AB silicone.
 
Regarding the nail polish I wouldn't even try to use it in direct contact with my ears... the lacquer for silicone is not the same as it probably need to have some flexibility after curing and also need to adhere to a different kind of material like silicone ( I am not 100% sure though). There are matte lacquers and shiny ones type...I am not an expert on silicone molding.
Making professional molds from silicone requires getting the right materials if you want to have good results.

The only 60003 I have is damaged and unfortunately not suitable for FR or Z measurements. It measures Rdc at 19 Ohm, while regular 22955 is 20 Ohm.

Well, thank you. From the following list only the 22955 have Rdc of ~20ohm
 
http://www.knowles.com/eng/Products/Balanced-armature-receivers-and-speakers/Radio-communications/CI-series-balanced-armature-speakers
 
 

CI-22748-000,CI-22762-000,CI-22955-000,CI-22960-000,CI-28487-000,CI-28597-000. ​

 
The 60003 might be similar to the 22955 after all...still impedance and FR measurments need to be done Only @Squirg can help me now...

Still I'm going to say you cannot take Rdc at face value. If the coil inside is highly inductive (typical design for woofers) you can expect quick spikes in Z curves and completely different FR. Two drivers with same Rdc can have completely different FRs.
 
Consider this, to order 60003 you have to order certain amount of those per year which is in kpcs, why would you go through all the hassle just so you can have a driver that is readily available (22955) and probably cheaper in those quantities. They simply cannot be identical.

 

[ForceMajeure]

I agree with you, also this could explain why I am having extreme difficulties replicating the correct response using the same crossovers (or maybe the 2389 used are not 2389).
 
Something weird is going on, I have been going through elimination process step by step checking every component.  Trying different batch of drivers, still I am either doing something wrong or the driver is not the same...

Hmm sorry I actually thought the two CIs are the same. However, you can actually buy the CI60003 off Taobao. They also have several different kinds of 6xxxx series on offer too. I saw a 37QP007 (used in the VE6) for sale too.

We still need to test this
I am hopping @Squirg will agree to measure impedance and FR on his rig so we can compare

I'm on it, Force!  I'll get it on a graph tonight compared to a 22955.  Stand by...

 

[ForceMajeure]

You will have to measure the impedance chart. If you know how to do it. 
If not I can tell you how, so you could measure impedance graph on any headphone from now on using what is called a "Jig" ( a few cables and a resistor) using the software Limp that comes with ARTA.

I don't have a impedance jig but I've been meaning to make one for some time now.  This will be a good reason to whip one up.
