Just listening to The Wall disc 2. Yes this headphone can do this kinda music, there is no doubt.
Again...still early days for me...but my thoughts so far.
As I pointed out somewhere in this thread that the 800/S as good as they are, through no fault of their design, do not really accommodate all recordings as well as they should…sound-staging, image separation, depth are not necessarily attributes nor the first thing that comes to mind with most pop recordings and studio engineers, the 800/S out of the head presentation will somewhat alienate the listener as the initial intimacy and immediacy is lost.
And that brings up my love hate relationship starting with the HD580 – HD6xx series, light and comfortable to wear for extended periods, modular to easily accommodate home repairs or modifications and of course the sound which never appeared to offend which IMHO is/was their Achilles heel, sure jazz and classical were always somewhat fine but music that was intended to sound edgy and aggressive…wasn’t…. and for my preferences I always missed that little something that makes a recording alive.
The HD700s addressed this somewhat but for some a quirky polarizing headphone and the initial discovery that the 660S may have incorporated the 700 driver or a derivative of such perked my interest.
Well after a few days use I think I can safely say Sennheiser pulled the 600 series out of my personal doldrums….not only that.. but my other wish was that the 660 hopefully mirrored the 800S tonally…and as far as I can tell the pair do maintain a very similar palette (definitely not the case with the 600/650s) so that only the staging pyrotechnics have been addressed and one doesn’t have to adjust their ears when switching between the two.
So for 800/S owners I can whole-heartedly recommend the 600S as a worthwhile accoutrement and maybe even a necessity to getting the full enjoyment out ones music collection.
As for stick in mud 600/650 diehards the answer is not totally apparent as it comes down to preferences, music, listening habits etc, etc.
For those looking for a new headset that is IMHO faithful to the recording, a pleasure to listen to without any extra bells and whistles to distract, while staying lively and entertaining without being aggressive… the 660S should just be the ticket.
