There is another custom company whose name escapes me now. I have the link at work (at least I think I do) and I'll post that tomorrow. Ok, the appropriate synapse fired, it's HearYourself.com... Custom Molded In Ear Monitors (WARNING - do not view in Firefox, their site is a wreck and they're working on it) and they have two lines. One has detachable cables and the other has fixed cables (about the only real difference I see) and if I ever scrape together enough cash again I'd go for a pair of the C2's. I like the lower sensitivity rating as that should make them less hiss-prone than the abysmal Livewires.
