Pro 900 has always been my favorite EDM headphone. (and check my page, I have owned a great many at this point!) You could try a Pro 750 if you could find one cheaper. They are fairly similar in sound sig. Thing with Ultrasones is that they have a very tight hard hitting impactful bass (when amped decently), which in my opinion, makes EDM a joy to listen to. If impact is what you desire, and a shimmery-sparkly top end, ultrasone will be your friend. It makes music very engaging and exciting.
Some are sensitive to the treble, but others (like me) are not. This is the case for many other cans. I have noticed positioning matters with the Ultrasone, I have my ears toward the back of the earcups. If I move my ears closer to the front, the treble becomes icky and harsh. I think this is what people notice when they try these quickly and don't learn how to wear them better. I automatically put them on perfect now, it's not like it takes effort, but in the beginning it is something to know about them.
