Best Praise

“Koss also made the Porta Pro in the 1980’s and clearly didn’t copy this design. Many headphones from that time period looked like this, and let’s all be honest. Koss clearly had a superior design. Hence why it has stood the test of time.”

“Yea so after 10 minutes of listening, these sound terrible. Very comfortable tho! The koss drivers were definitely made to be on ear, being that far away made it sound like a phone speaker”

Best Praise

“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.”

“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”
