I've come between the Pro 900's and the Beyerdybanuc DT-770-PRO 3
Which one? Are there better?
If you want it to be portable as well, the Ultrasone Signature DJ would probably be the absolute best you could go for.
The Fostex TH600 and TH900 are usually considered the king of the hill for EDM for home use.
One thing to note with the Pro 900 would be the wild and untamed treble. I liked the DT770 (80 ohms) a hell of a lot for EDM when I tried it out.
