So I have been using my HyperX Cloud 2 for about 2 years and now I want to buy myself some studio headphones, but I don't understand anything here. I made a purchase of the Sennheiser HD 560S (120 ohm), but later today I found for the same price headphones that have more ohms. I found for the same price the DT 770, 880 and 990 Pro. I found out that the 990 have a 600 ohm option (I don't understand ohms at all). At the moment I don't have the money to buy a dac and I searched how many ohms can my motherboard support. It says up to 600 ohms, which on paper sounds great, but at the same time impossible. So at the end I want to get some good headphones for around 150-200$ and I don't understand anything about ohms. I'm sorry if the question is really dumb, but I really don't understand what should I pick.
