AKG K7XX for gaming... which is exstreamly rare these days. Bright and comfortable.
HD600 for everyday music and is always on my head. Comfy and just great overall.
DT770 if I just want peace and quiet. Pretty much glorified mufflers at that point. Very comfortable to wear and great on bass... too bad I don't like bassy music.
DT880 is ok, extremely bright. I use it at my office.
HD598. Comfy. HD600 is almost a direct upgrade of it though. It is gathering dust after I got the hd600. I am planning on bringing it to the office one of these days.
I bought the beyers because of comfort, but for some reason I found the sennheisers much more comfortable. Probably because I have elephant ears. I used to wear computer glasses(basically gunnars, but medically perscribed) and beyers were definately more comfortable with glasses on than sennheisers.
BTW I use all these with an amp. Cable replacements can make a difference.
I use a fulla 2 currently and never really though of upgrading further. I listen to mostly chillpop/chillhop and heavy vocal music time to time. I prefer soothing and piano heavy music compared to EDM and Bassy. Honestly, it is probably my preference on vocal music that I like bright headphones more.
