the L-cushes don't bother me, but i know some don't really like it, but i can say they are more comfortable.
as for the sound difference it's been so long ago, other than i know i pr
i agree the generics are softer, but of the ones i've used, the shape, dept of the bowl aren't the same. the grado's are deeper, i very much prefer the grado pads
With the generic G-pad its a hit or miss thing, I ordered from 4 different vendors and they were all different, found the one that sounds best to me and ordered a few more from the same vendor. Its not only the depth of the bowl, I've seen differences in the rise from the face of the driver to the slope of the bowl, even the density/softness of the foam varies.
