Seconded! i'm watching out for a ex1000 set and will be removing the entire rear connector section and replacing it with a custom 3d printed/molded section to make it much smaller and with a 2 pin connector for wider compatibility with cables, and also to place that connector in a better place, hopefully! with the way they are shaped, I see huge potential for much better comfort. need to separate it to do this, and would probably look inside eitherway lol.
the ex800st has a pic of it taken apart a bit on here and it seems like that's held together in 2 main sections with a lip and a little gl;ue in the corner, but with the metal material of the ex1000st, it is less likely to be using glue I guess? it's still fairly likely that it's just a matter of prying though
I'm excited at the prospect of trying custom housing materials, like resin or wood and maybe making some artwork on the outsides (fight me purists haha) such as some japanese lacquerwork which I think would fit soo well
