Bit of a strange one.

I have a set of headphones that use two different ground lines, however that cable broke and I swapped part of it to a cable that uses just one ground line. Will there be any major difference in sound, like a crossfade? I'm 98% sure there shouldn't be but I wanted to make sure.

I do not see how it can make a major difference.
As long as the new cable is in comparable quality to the one it replace, and that it used to and still use a plug with common "ground". Aka -> TRS.

All single ended cables share a ground if not at the cable level (k702) then at the plug level.
