hmmm, will it be possible that company like sennheiser got a third party company to produce their IEM, and this third part company also make the fake and real sennheiser earphone? Just my guess.

hmm well iems are cheap to make.as stated by other members yea they are mainly produced in developing country. overall the cost is really low... well working in the piracy world will be enough for people in china to survive. Whether is it earning a lot or not is a different matter. How many of the people in the piracy world actually got rich? maybe those people who started the business way back, years ago but now with the competition out there, getting rich from piracy is kinda hard.
