Wow I just seen this and didn't know about this huge moster "2000"..
Unfortunately what bothers me is two drivers overlapping each other at what looks like all frequencies albiet attenuated but still probable low level interaction with unknown results of differing phase and reponse and decay, etc.
Anyway it was a good try but I can see the 680 cans easily having more clarity...
I am just wondering how these are to the s500 because that is same size driver and those had a slight v-shape..
So far these are only compared to the s400 which I considered mid-centric..
So are they like both?
S500 is more "fun" than S400 due to a more V-shaped signature.
S680 is more "fun" than S400 due to improved bass, treble and soundstage. "Improved" doesn't necessarily mean that there is more bass and treble, just that they are better.
So yes, I would say they are a perfect combination of S400 and S500 - plus much better comfort.
