I have tried fidellio x2, dt 1990 pro( these sound amazing but don't let a lot of air in and your ears hurt after a while), hd 660s(really uncomfortable clamp for me personally) but I still prefer my hd 599's which I've had for years and can wear for hours. Super comfortable and sound really good too.
I think the dt 990s are meant to be good too which I might give a try
