Had this for ~2 weeks now and I must agree that it is pretty flat. Listening to EDM, the bass doesn't really extend that low, but there still is bass presence, pretty well controlled, and really not fatiguing as compared to Final's Heaven III. The thing that blew me away was the mid-high and the wide soundstage.
The only cons I have is that the cable connector do get loose and I'm afraid I might loose one side of it while out and about.
@Jyri I tried to plug in the cables all the way but it still seems that it's a bit loose. And for the bass, the mic cable does improve the bass. Thanks for the advice.
