comphy pads--- used for sr-60, you can cut the center open and put it on reverse style,
it puts your ears closest to the drivers, thus providing alot more impact via midbass, and midrange, also warms up the sound consideribly.
flat pads, a old standard pad, which placed the ear a little bit further than the comphy, gives a bit more dynamics than comphy, but still retains the warm sound with alot of impact
very good option for aka harsher cans such as grado sr-325
Bowl pads, the new standard, uncomfortable compared to flat or comphy, puts the ear much further away, creating more detail, less warm sound. It takes away from the thumping midrange, and I think give much more soundstage.
however these are I think good for cans like the RS series, where the sound is already warm and a little less detailed than the 325-225.
it's all preference
I mean the pads make a huge difference on the sound of grado's
I think the 325's with flats are great
i think the rs-2's with bowls are great
