I was thinking about returning my dt 990 pro’s for the SteelSeries arctis pro’s with the dac. I have had my dt 990’s for 1.5 months so I don’t even know if I can return them. I have not gotten a dac for my dt 990’s. I am just unsatisfied with the dt 990’s sound. I don’t know how much of a difference a dac would make for a 250 ohm headset. Which would be better SteelSeries Arctis Pro’s with the dac, or Dt 990’s with a dac. I like to casually game and watch movies.
