I doubt the highs are as bad as ppl say. I own the DT 990 which is considered by some to be gawd awfully bright, so the only issue I have is the Seal. And btw Dyanamex was helpful in making my w1000x one super Tight headphone.
And Oh wow SUPER DUPER headPhone Bending to the RESCUE. -.-
Hey Mshenay, DS21 asked about it and I will too: what exactly is Dynamex? A Dynamat knock-off?
