Headphoneus Supremus
I had the R9's, but moved them on. They lacked too much clarity for me.I love them to death, but I still wouldn't recommend them just because my taste in headphones can be so odd. They're basically built for classic rock, though. They do rap and the like well, but any genres softer than those are ill-suited for these.
I do plan on keeping them though, and I feel like I got my money's worth, even disregarding all the extras they come with. To any sane person I would recommend the R9 over them, but if you've got a screw loose like me, R10D all the way.
I just fear I would take a beating on resale if I don't care for them.
But I am always wondering about that "hidden gem" that I might miss.
