I'm not sure of his shop but I do know the guy that distributes JHaudio. (Custom In Ear Monitors as used by a number of famous artists).
I'll PM you his number if you want. They use to handle Audio Technica.

Another alternative is if you try to contact BigKnob Malaysia. Ask them if they do (if i recall right they did mention to me quite a while back that theyre considering bringing in a brand or two into Malaysia).
