I have a pair of Graddo SR60's. I'm generally pleased with the sound compared to the cruddy cheapo headphones I've used in the past. One thing, tho: When I move the headphones slightly off my ears -- where they're still on the ears, but not pressed on fully -- they seem to sound brighter and clearer. Same if I, oddly enough, yawn or open my mouth (same effect, I assume). I read somewhere in the past that there were people cutting small holes (dime-size) into the foam earpieces to obtain a better sound. Anyone tried this? Thanks.
