I'm on board with these. I just got them used from Amazon, and first impressions are very good. In terms of just sound, they don't quite topple my current IEM favs, the Radius DDM2, but they come pretty darn close. The MMDT's offer exactly what I was looking for: DDM2-similar sound sig (I consider myself a moderate basshead) with a more durable build and better isolation.
The DDM2 does have better soundstage and sub-bass, which I miss, but I'm sick of having to baby them around all the time; I've already broken one pair so now I'm afraid to use them out and about. I previously tried the Turbine Pro Coppers to fulfill my "daily IEM" role, but they had too much driver flex. The Miles Davis still have a little bit of flex in the right ear for me, but with smaller tips it becomes a non-issue. I'm using the orange Sony Hybrids right now.
Anyway, I am very happy so far with these Miles Davis. I wouldn't say they are really a good bang/buck value, but if you can find them used, then that's about right. You do get a ridiculous set of accessories and packaging, so even up to $250 I could personally justify for these; $150 would be a steal. I don't see much point in getting them new anymore, since the main reason to get them BNIB is to get the super warranty, but Monster is replacing them with Trumpets now. =/
