Absolutely amazing
Using alongside the Xonar Essence STX, this is my first high-end audio setup. I'm relatively inexperienced with the tech behind sound, being more of a videophile myself, but I do know high quality sound from average sound, and my preferences in sound are a bit more strict than anyone I know.
Phenomenal sound on all levels; absolutely breathe taking. Smooth, amazing sound that completely immerses you in what you're listening too. Extremely comfortable; I wear them for hours every day and I don't feel right sitting at my computer without them on my head
Have had some issues with the drivers handling bass intensity on some things; but this has been worked out for the time being
