My DIY Modded KSC-75, absolutely loved the sound. Keeps me company before i get a new pair of headphones after the tragedy.

Recabled using canare starquad cables. Changed the pads, padding from an old altec lansing ( better bass impact, night and day difference, but killed the highs ). Taped the center of the mesh ( bring back the highs!! ) 

nocar:
recabling is pretty easy. First, u need to take out the earhook, just pull it off from the headphone.
Then u need to take off the cover that covers the solder joints, its below the earhook and in a darker grey colour, u can see in the pict that i had cut the cover in half for more movement space for the earhook.
After u took out the cover, u can see the solder joints, just unsolder them and solder in ur new cables. The workspace there is pretty tight so be careful though =)

Sry i didnt take step by step pic and for the late reply, was away for cny =)
