Detailed walk-through on replacing the SHP9500’s pads and giving it a nice flush look:
As for these pads, definitely gives a nice bass boost and provides slightly more isolation but doesn’t negatively impact the openness of the headphones. Super comfy and adds a little clamp which I needed. Most important of all is that there is now much better depth so that my left ear lobe doesn’t touch the inside of the pads. Fantastic bang for the buck!
