Best headphones for music production with a good budget

[zenophilix]

Thanks everyone for your input.
I don't need them to be closed because I will work in a separate and quiet room.
Sadly I can't test any of the headphones cited here since the nearest store big enough to have them is 50km away from me, and also I'm not sure I have enough experience to judge them right.
To be honest I was hoping that the winner would have been the HD800, so it would have been easier to choose.
Instead it seems like the winner is Beyerdynamic DT880 Pro with Sonarworks Reference.

Honestly, the winner is the one that sounds best to your ears. If you can, try to find somewhere that'll let you test them. I was able to plug the 800s into my phone at Best Buy.
