I've been looking at these two to replace my current gaming headphones. I know there are lots of posts and articles comparing the two, but how big are their differences really? If it's super minimal I might just go with the kph30i, remove the back foam if necessary, and throw some yaxi pads on it. If the ksc75 is actually a lot clearer than I'll go through the hassle of buying a headband and pads for it as well.
