KSC75 adapter for Audio techica AD500/700/900x headphones

This is a very simple adapter to fit the KSC75 driver into the AD500/700/900x headphone housing.

The top ring has channels to not break the pins on the KSC75 as those would otherwise have to be removed which I did not want in case I ever move the drivers out of the headphone again.
This mod requires no use of glue as it get clamped by the original holder for the ADx driver. Regardless I do recommend using blutack to fill the edge on the front pace of the driver after inserted into the adapter.

Happy modding.
