So I got a second hand CIEM (64Audio A18T) from my friend last year and sent it elsewhere for a remoulding. 64Audio wouldn't do remoulding for second hand buyers.
The audio was much clearer on the high end compared to any IEMs I used before. Maybe it is for the rigid and direct sound canals compared to foam or silicone tips.
The fit was not very good but that is fixable with some modelling putty.
And a few months later I decided to fix the bad fit for once and all. I bought ear impression supplies and took one myself. Tried to go fancy with 3D printing the shell but I never got the 3D scanning part to work out.
End up losing one side of the CIEM to the depths of my workshop, and now I am back to using my old Shure.
