They're finally here. I can't really say if they are 100% identical to the standard 598, but they probably are. There is one thing that really bothers me: I think there is something wrong with the right headphone. The left one is really comfortable, as if my ear were floating inside the headphone (just as I remembered while using my friend's 598), but the right one's inside really touches my ear(as if it were smaller), and after some minutes it's annoying. I tried my friend's 598 for quite some time, so I know it's not my ears that have different sizes, and I immediately noticed it while wearing these new ones for the first time. Feels weird. Might return it and just go with the regular 598.
