What woodworking tools/machines would be needed to make some custom wood earcups like on the darth beyers or thunderpants? Thanks

What are some of the most mod-able/customizable headphones BESIDES the Fostex T50RP? Thought I'd start a thread to help out people thinking about modding headphones and compile a list of the best headphones to mod/customize.

As the title says I'm wondering how to disassemble the Sony mdr-xb500 headphones, any help is appreciated, thanks in advance.
