ahh, the Senn mods.
I never thought the foam on the grill side can be removed. but anyway
Yes, I would say there is big difference of sound signature after this mod. For some people, they would describe it as the "veil" is gone.
but anyway, if you are married.. or if you don't care about the strange looks that cashier/people might give you when you went into a convenient store to buy stocking then this this:
first, get some stockings. (color does not matter, recommend dark color though, the small color difference does not matter since you are going to stretch the stocking as far as possible anyway.)
first, pull those ear pads away from the headphone
Second, cut a peace of stocking about the same size as the ear pads, put once corner of the stocking onto the earphone, press the ear pad back into the earphone by one corner.
Third, start pulling the stocking on the opposite direction of the opposite side of ear pad where you just pushed back into the headphone.
pull as far as you can, then push that corner of the ear pad into the headphone.
Fourth, do the same with the other two, opposite side of the ear pad.
Fifth. after you secure the stocking material (remember, STRETCH IT) pull the remaining stocking that is hanging on the outer side of the ear pads away from the headphone, then cut it next to the headphone.
the stretchy characteristic of the stocking will make the stockings shrink into the connection between the headphone and the ear pads while make sure the stockings stays in the same place.
then, there, your mod is done.
the main purpose of this mod is to keep the same sound signature of Alex's mod while preventing hair, dust, dandruff from touching/get onto the drivers
