I have lost the cleaning tool for my brand new Custom-3 headphones and I am wondering if anybody knows where i ca get this tool. One BIG DOWN FOR KLIPSCH is that they do not offer any accessories for sale and now I don't know what to do if I need to clean my headphones. I guess i will end up using a paper clip! Please advice

Just use the end of a small plastic cable tie on the gels.  Not as flash, but just as effective. 
It worked well on mine (haven't lost the cleaner, just didn't have it with me).

I wouldn't poke it down the hole in the actual earpiece though but if you keep the gels clean ear wax shouldn't get that far.
