I've owned a pair of Grado SR225s for about 20 years. They still sound great. But while the original earpads lasted quite a while, I've had to replace pads with increasing frequency over the last few years. They just seem to disintegrate fairly quickly. Is anyone else experiencing the same issue? I got tired of paying $20 a crack for replacements, so I just ordered Geekria's replacements on Amazon. They've got a 4+ rating and cost half what Grado charges. I don't have them yet, so I don't know how good they are. But I was wondering if anyone could recommend something you could use to treat earpads so they don't disintegrate without impairing their sonic qualities or comfort level.
