I have tried to love these headphones, but I couldn't get past the overly warm and dark sound of these cans. I have modded tons of Grados and other headphones, so I took a shot with these. Remove the earpads (more on these later in the post), and then the six screws holding in the ring and the plate the driver is mounted on. There is a black felt cover. Grab it by the edge and peel it off. Reassymble the headphones and kiss the warm, dark sound good-bye.
That felt is the issue. It is thick, you can barely see light through it when holding it up to the light. The sound opens up considerably, and it is night and day. You can always put the felt back if you wish. Mine came off with a little tucking and had no tears in it.
The earpads.....the pleather ones darken the the sound, while velours give it more sparkle. Removing the felt trumps pad replacement. Try it. You can alway reverse it.
I can't believe I'm the only one to try this.
