This will not work for the most people, since the nozzle from the SR-002 is very wide and big. If you put a typical custom tip/sleeve on top, the SR-002 sound signature will change very bad (i.e. extreme sibilant treble), I tried this method already.
Here my 1st round:
Looks ugly and changes the sound signature really bad as I said before.
Here my 2nd round:
Here is the nozzle is untouched, sound does not alter at all, but since it's very big, this wont work in small/medium sized ear canals, the only chance if you have really big ear canals to get this kind of custom version. If the nozzle get smaller on SR-002 = you will decrease sound quality massively on the SR-002 so regular custom tips/sleeve won't work at all.
