Tips for modding: I thought these were a bit lacking in treble and far too exaggerated in upper/mid bass, so I ordered some Yaxi pads meant for the Porta Pros. While changing the pads, I also removed the foam between the driver and the exterior openings. They now are much more comfortable and sound a little better, especially in treble extension. Still need some EQ to get them where I like them as the bass just feels boomy and overpowering no matter what, it seems (this is coming from a Grado/Beyer/AKG fan so YMMV and all), but overall it's definitely an improvement. Will probably stick to KSC75 though as I just prefer the brighter/snappier sound.
Edit: removing the foams might do more harm than good, it seems they keep the bass in check slightly. But these things still put out a crap-ton of bass regardless.
