I have to confirm: HD800 are not fun sounding. I tried to apply some EQ but i admit i didn't find a pleasant equalization for my tastes. The thing is used them many times in the studio, as i used them for headphone-mixing as a reference for monitor speakers in order to do perfect mixing balancing the outputs. In this way you have a good trade-off between the impact of the monitor speaker and the compensation in the detail of the headphone. In this kind of sector, the HD800s are divine. If i had to choose a headphone to be used in listening sessions, that wouldn't be my choice. I would prefer another kind of headphone, I mean.
