Does anyone have suggestions on carefully removing foam from the baffle of headphones? I am reworking some AKG K240 Monitors I got off ebay with new pads, recabling and new elastics. But the old foam is dissolved onto the baffle. Should I just very carefully pick the stuff off with tweezers in the holes in from of the driver and then carefully scrub off the rest or?
Also the fiber paper over the baffle on the left cup was in bad shape. Anyone know what this is and where to get replacement material?
Start with a rocket blower (a thing photographers use to blow dust and debris off their lenses) or something similar.
Don't use compressed air, that could destroy the driver.
Then use tweezers to get the larger parts out - BUT USE PLASTIC TWEEZERS - if you use metal, the driver magnet will pull the tweezers out of your hands and squash the diaphragm.
I'd then use any off-the-shelf 'sticky-stuff' remover to get rid of the rest.
Not sure what would make a good replacement for the vent material.
Going down the DIY route you could start by trying out microporous tape (first aid kit tape).
Then try coffee filters. Paper hand towels. Stockings.... Just anything porous you can think of really.
