I was thinking of getting the RH-300 to use as my new (electronic) drumming headphones but I'm worried it won't isolate the stick noise enough (for reference: the vic firth isolation headphones are superb at it), is it possible to replace the ear cushions and turn them into sealed headphones?

Its possible to mod the pads to increase isolation, but it will affect their sound.

I guess my next question is where do I buy these pads?

And how will I know what size pads I need?
