I'd like to get my hands on a set of the velour ear pads, but I'm not sure where those can be had in the States at a reasonable price.
The foam separator that goes behind the ear pad and over top of the driver dry rotted on my set as well. I vacuumed the chunks out and cut some pieces of felt to replace them for the time being. http://www.amazon.com/Handel-Water-Music-George-Frideric/dp/B000001G4Q/ref=sr_1_sc_1?ie=UTF8&qid=1333331827&sr=8-1-spell
My K240M, also have the foam inserts (sepatator) disintegrating in the cups
The company, Full Compass, sells the AKG foam inserts (foam separator) for $2.99 each, plus $8.80 shipping.
I ordered a pair for $14.78.
Decided for now to use the foam inserts from my Samson SR850s in the K240Ms
Tonight I made the mistake of trying to open my K240 Monitor 600-Ohm to clean out the foam pieces around the capsule (diaphragm).
Found out you need to cut the two wires (red/white) to get the cup fully apart, decided not to cut the wires, did not have soldering stuff handy.
With the cup partly open, pieces of a disintegrated foam ring came out.
Look like I have to figure out how to make replacement foam rings, or order direct from AKG,
Well, my wallet was feeling a little too heavy and over stuffed.
