Looking to upgrade headphone, listening to EDM and own a small amp

Like I said in the title, I am looking to purchase a second headphone in the price range $200-300. Could be a little cheaper or expensive, of course. My first headphones were the Audio-Technica M50, which I still really like.

I have the Fiio E11, for additional boost in the low frequencies.

I use the Sansa Fuze with line out to the E11 and then to the M50

I listen to EDM (Electronic dance music, which consists of trance, house, minimal, dubstep, techno etc.)

I just simply want a superior sounding pair of cans, but at the same time, don't wanna spend much, much more than I initially spent (around $110). $300 I would have no problem spending if I can a pair that convinces me, I hope you get what I am trying to say.
 

I've done a lot of research before I bought those M50, I was between that and the Ultrasone 580/DJ1's. However, for this one, I am kinda clueless

Please help :) Thank you

I was looking at the Pro 900, thanks for the suggestion.
Doesn't have to be a bassy one, my first headphone was for sure on the heavier side. But at has to be at least average or above average on the lower frequencies, since EDM does not sound right without bass.
But yeah, i dont wanna exclude myself to only bassy headphones, I am open to any :)

Thanks, I'll take them into consideration for sure.
Any other suggestions?
I'd like to have a small list, and could do some research on them.
What do you guys think about the DT-770 or 990? Or Sennheiser HD 600 for example?

Thank you, I'll take them all into consideration, and prob take the sennheisers out of my list.

Pro 900 is gonna be for sure on the top of my list. Thanks
