TF10 doesn't have covering for the two holes. (I don't know how to describe those two holes, but thats where the sound comes out.) I have dry-type earwax, and it's a bit difficult to clean, especially since I can't see clearly inside the holes and might not notice small bits of earwax that's not stuck on the sides of the holes, but actually fell in. Any way to clean inside the holes?
The third image describes what I mean the best. I can't see the bottom well at all, and don't know if anything is there. As a producer and owner of dry, flaky earwax, would any small, fallen pieces (as shone in the first two image) damage the IEMs? After all, if I'm not mistaken, aren't the red and yellow objects within the sound bores simply filters? Would touching it even a tiny bit damage it? If not, how much resistance does it have to breaking? (As in, how hard would you have to touch it for it to break?)
I am aware of the Comply TX-500. However, I'm thinking about getting the TF10 re-shelled with my ear impression. That brings another question: how do you clean the custom IEMs? Sorry for the many questions.
