After listening to the Denon AH-D7200 for a few days, mainly metal, I think they are fantastic for this genre. Very engaging and fun, yet detailed. I wanted a closed back headphone, and compared it to the Focal Elegia and the D9200. The Elegias were anemic in comparison. The D9200 were also great and perhaps slightly better (tighter mid bass and a bit more sparkle in the treble) but not worth the big price difference in my opinion.
It's a fun sounding, comfortable headphone with descent isolation and a terrific build quality, I paid 719€ for mine at a local dealer and I know they can be found cheaper in other countries, I can highly recommend them. Would love to compare them to some of the ZMF headphones at some point, but there are sadly no retailers here.
