It's a second hand unit. Considering what I paid blegh(i bought from him), it was a steal. I can't wait for the new DDM II to come. 
Hehe, you're right, the black isn't as unique. I just came back from Giant, and every eye that looks at me were towards my ears wearing the DDM.    Interesting if I were to wear a red one.
Oh I think I'm not that sensitive towards incoherency. I don't realize any oddities at any frequency.
If blegh didn't sell his off to me, I'd eventually buy a new one from Jaben, and I'd happily pay for that price as well. 

EDIT: Actually, maybe I wasn't aware of what to listen to, I do find something just a tad bit odd, but not really bothering. At some parts, the bass can sometimes sound a bit different than the whole music. Like it's an entirely different entity.
EDIT: Or maybe it's the treble, can sometimes sound a bit muffled when the bass kicks in, but is quite apparent when not much of the low stuff is going on.

Is that incoherency? It's my first time ever taking notice of these things. 
I end up using the medium Radius ones. To me they open up the head stage a bit more. The Sony ones does give a better high end though, at least according to my ears.    Plus I don't have to push it in as deep to get the seal, and yet still produce that vacuum seal that the Sony also gives.
