Don't get it
Do you mean different type of casings? Metal, plastic, etc? Wow... not sure I will have the time for it
But this could probably gives some indication:
I made that video long time ago for my Fiio X3ii review.
Analog cable is for sure affected. But depending on many factors. That's where balanced interconnections shine.
Sorry OOT.
My point is that not only USB cable is the 'entering door' for EMI/RFI: casing, printed circuit design,analog cables, headphones and your body resistance if you are touching the casing or metallic parts of your headphones, etc.... I am pretty sure you are aware of it but probably not everybody is conscious.
In short words USB isolator devices are not allways sufficient for getting ride of interferences.
