  I'd go with the HD598s or the X1s. I like a wider sound-stage and more neutrality than the M50X can offer.

Sounds good! I don't think you'll be disappointed by them! The audio cable that comes with them is pretty long. Depending on your setup this can be good or bad. You can get these cables that come in all different sizes, I have the shortest one because my amp is about 2 feet from where I sit. I was concerned with quality, but they're actually really nice for their cost.

Just wanted to come back and thank you for helping me make the decision. I ordered them today, the special edition black which comes with the normal cable and for 100€! So yeah lol I'm pretty happy now
