Denon HP1100 Headphone MOD for removeable Cable

Good day, I hope everyone is well. Has anyone done a MOD on their Denon HP1100 Headphones and removed the fixed cable, and put a 3.5mm insert insert in to be able to make a cable be removable? Also, (long shot) would anyone have a CAD or Mechanical Drawing of these headphones? I just want to have a look at what I may be getting into. Thanks and be well all, Ethan

I would put a mini-xlr socket. Then you can buy OEM cables for Pioneer HDJ-2000 and AKG headphones or build your own.
