I apologise for my English right away. I have been looking for my first open-back headphones for some time. I looked through tens of headphones and reviews. And these models caught my eye: Sennheiser 599 Beyerdinamic DT 990 (32 Ohm edition) AKG 702 (or 7xx) Phillips fidelio x2 I want to use headphones without an amp or dac, because I'd like to use these headphones with my phone. My main use is gaming (like CSGO, Tf2, Gta5, Fornite). As for music, I listen to hip-hop and pop. I'd like something with a wide soundstage. I'd like something more than a neutral sound. Budget: under 300€ Thanks in advance!
