Compared to women, IEMs are generally less sibilant, harsh and tend to have a more balanced response. They also could be considered to have a better bang/buck ratio and are much easier to move on the FS forum when you grow tired of them. When you factor customer service into the equation it really becomes a no brainer.
Well, here's the thing about BA's for me. They have a unmatched ability to image clearly and realistically compared to dynamic IEM I've heard so far. If you can provide superb timbre, low-end presence and coherence in a multi BA they can be quite superb. My ES5 is the closest for me yet. Most of you know I was a steadfast DD guy and probably considered more of a basshead by some. Only the DBA and ES5 were able to make me switch hit. I don't doubt that the FX700 is an inevitable purchase for me though. This time the lack of isolation being an asset rather than a hinderance.
True for my Miracle as well. I saw a post on TechEnclave comparing the Miracle to FX700 saying that the timbre of the Miracle is 50% better. I don't find that to necessarily be true (or quantifiable for that matter) but the Miracle can definitely compete in timbre with the best dynamic driver earphones have to offer. It's much like the SM3 with but proper treble energy and less thickness down low.
