These aftermarket pads replace the high end size series "G" cushions that come standard on Grado GS1000x, GS3000x, PS1000, PS2000 headphones but they could also serve as a very nice upgrade for all SR, Hemp, All RS, All GS, PS1000, PS2000 series and possibly some other brand headphones. The material and open center design work together to enhance bass tightness and clarify treble vs Grado stock full foam found on the SR60, SR80 and SR125 series. So, yes in a way they offer a hybrid "life hack" upgrade to these models. The large outer circumference of  the G series pads provide unmatched comfort for hours of continuous use.

Includes removable free ultra thin covers to protect the foam from oils, thus increasing the life of your foam.  These pads are guaranteed to have functionally the same look, feel and comfort as genuine grado G series pads.
