Yup so i removed the foam, settled on a flat cotton pad for the rear of the inside of the cup and a fully opened unrolled cotton ball running along the inside of each cup. The result is a tamed smooth bass with a deep and BIG/airy sounding soundstage. Its well controlled for rock and metal music and perfect for jazz and classical. Just compared side by side with the pro 80s, the sub bass seriously sounds lacking in the pro 80s while there is alot of midbass. The treble as always in the pro 80s is somewhat sibilant and too bright, and a much more linear with a smaller stage. In comparison the isk mdh9000/marrantz mdh-2 sound very large and deep sounding like full speakers. Its like being in a tube sound vortex, very satisfying! The stock pads feel like marshmellows on the ears, very plush and soft. The only complaint i have at this point is they are not for people with small heads, im still working on a proper mod in this department. For the record the pro 80s fit me perfect, i extend each side by about 3-4 notches so my head isnt that small...just the isk's are meant for big noggins lol.
