I have a Dt990 Pro and i can tell it doesn't work bad for AAPG, it maybe has a bit too much bass and that is why i replaced it with a 598se a while ago. Granted, the 990 is not bad at all, it's just that the 598 is way more neutral and also sounds sharper (the 990 is better for listening to music, it's warmer and smoother).

Is the position audio good on these headphones?
