Thanks for all the info on here guys. I am starting to save up to buy some CIEMs from 64 Audio. I just got impressions done so I can have earplugs made. I was going to send those same impressions to 64 Audio to use.
Refer to this impression guide here to see if your set impressions conform to the specifications:

And few other things to consider:
1. I have heard that some silicone earplugs require a closed-jaw impression. You need an open-jaw impression for a 64-Audio IEM
2. 64-Audio needs the impression to be as deep as ~4mm beyond the 2nd Bend. I am not aware of the depth requirements for the impressions for ear-plugs but you may want to check.
3. For Custom IEMs, the manufacturers need a bit of extra material on the outside too. That could also be something that is different from an impression that was made for ear-plugs.
Just my 2 cents..
