Best praise vs top criticism for Beyerdynamic DT 990 Pro
Best Praise
+102 pts“Your take froze the stream next to my house. That said, DT990 has benefits when EQ'd including stronger bass, bigger staging and a lack of a certain kind of harshness or contrast that bothered me with the 560s even after a Harman EQ.”

+21 pts“Sadly the cult that seems to have formed around the 990s is completely undeserving. I am sorry you dont like them and were lead to believe you would. The 990s are sadly just not a very easy going headphone. They work for some people but for a large majority of people they are just not enjoyable. If you can return them I would suggest exploring that route and maybe look at the dt880 if you want to stay within beyer or the hd6xx if you in north america”
