Does anyone know if the HD555/598 ear pads will fit onto the HD438?
Go to walmart or any crafts store and buy some thin felt, you will want to make two identical pieces of this, put the earpad you want to use on the felt and trace the outline, make sure it fits the back end of the pads ( meaning you cannot see any sticking out on the inside of the earpad hole. The inner portion should match the rings on the earpads it self and not stick out into the center of the hole, however you want to cut the other end wide enough to match the HD438s earcups dimensions. )
So the center hole in the felt matches the width of the hole in your earpads you wish to use on the HD438, and the

( ( ) )
^ ^ ends matches the width of the HD 438 earcup after you remove its pads
Perforate the solid ring section with holes with a hole puncher, try to leave 1/8 inch gaps between each hole, you want to try to cover at least 75% of the surface with holes
( o ( ) o ) <-- holes punched in solid areas, try to make them neatly lined up and covering roughly 75% of the solid area, too much is bad and the ring will fall apart, not enough and the sound wont flow through the pads nicely
Glue the felt pieces back to back both sides ends are sticky back, the sides with the flat non sticky material are the sides you want to glue together so both pieces stick together but both also have the sticky back facing outward ( you can do this before you punch out any holes if you prefer )
apply one of the stick backed areas to the back end of the earpad and try to be as uniform as possible, dont want it lopsided but thankfully its felt and can be peeled off if you mess up or want to swap pads. After that, simply apply the pad to the HD438s earcup where the old pad used to be and enjoy
any earpad can be swapped onto any other set of headphones with this method, how good it will sound is another question. It should not matter too much for open backs unless the new pads closely match the old ones in size and appearance.
Hope you have enjoyed todays lesson
