Hey, I really appreciate your review and comparisons of both of these headset. Because I am currently searching for a higher quality headset for music, gaming, and movies, and I wanted to ask if your prefer these to the DT990s and or DT880s? I know you said you had the open back 990s and that is what I am on the fence with was this pair, the 250 ohm 990 pros, the Audio Technica m50 or a9000x, and the COP. From reading many reviews I have cut it down between the 770, 880, 990s I believe. I do not know if I prefer open or closed back and that is part of the problem the ones I have had to date have been close and I am fine with them. I just wanted to your opinion on this if you could help I would really appreciate it. I am less experienced with audio peripherals that I would like to be.
