I don't think EDM is a con
Aside from the price, the Pro 900 can have a slightly metallic sound due to the titanium drivers, and they really need quite a lot of hours to burn in. People usually recommend 400 hours of burn in before the headphones really start singing, but I personally found that between 60 to 120 hours was when they really opened up.
Also, they have a slightly bright signature, but I'm quite treble sensitive and after letting them run for a few days, that smoothed out nicely.
Basically, they're ideal for EDM, but not so balanced for other genres, which I don't think it's much of a concern to you. Heck, I even use it for other genres and still love them If they don't feel right for a certain genre, I just EQ them and they're fine. Not to mention they're also amazing for movies
