I use Beyerdynamic DT 990 250 PRO + Creative Sound Blaster Z.
If I to sum up what I think of this setup in one word, it will be AMAZING.
The sound card is great and the drivers are excellent.
I have yet to experience any bug.
It's cheap and an excellent all rounder. Movies, Music, and Gaming !
It also have an amplified headphone jack with up to 600OHM headphones. So basically it make almost every headphone sound better, especially when you have one of the Beyerdynamic headphones as they shine when used with an amplifier.
Hope I helped.
