emailed Grado, they said that they use a special solvent and they don' reccomend that I try to remove the original cloth. they said they would replace them if I send the headphones to them but they want $100 + shipping. Hardly worth it for some fresh cloth. It would be cheaper to by some SR60s and take the cloth off of those. I may just see if i can just clean them somehow.
100$+ shipping, thats ridiculous, you can buy yourself a new pair of SR80i's for that much.
Also you can't take off the cloth and put it on another driver, it will not come off in one piece, some of it may but most of it will separate into strands, and you have to pick off a lot of individual strand that have more glue in some areas, especially around the edges. I may have posted this already in the wrong thread earlier, but I took the cloth off of my 80i's on purpose when I put the Vibrolabs (classic) wooden cups on and I keep the drivers face down when I'm not using them, and I have no trouble at all with them, plus they look great! I might even take them off my 325is's if I get bored one day.
