1. love the idea of custom IEMs, I use Shure's now and love that over-the-ear cable, and comfort (even if not custom).
2. Question: I like a natural frequency response - not an amp'd up artificial bass, think low Q, or stated in more popular terms, a reference speaker...so there's a statement in the description about a sort of unique sound signature, but doesn't say what that is. So...what is it?
