Umm...All versions of the A83s will work with any MMCX cable. That's not debatable. The little protrusion on the new cable only prevents you from using the new stock A83 cable on OTHER MMCX headphones. It doesn't matter that the little hole is on the A83s...as the only cable that goes in that hole is the stock A83. Regular MMCX cables will just rotate freely on both versions of the A83.
