The 600 ohm version is more refined with better controlled bass and less sizzling treble. Both are great cans, though. I had the 250 ohm version for some time and I found them to have a pretty flat response until the upper frequencies. Both have slightly recessed midranges, with the 250 ohm being slightly more recessed. Both are not as recessed as the 990s, though.

Thanks for any feedback.
