How come some headphone cables have mono terminals going into the headphone and some have stereo? Will a stereo cable work with headphones whose stock cable has mono L and R terminals? Thanks.
There's always just one channel going into one driver(the signal for the left channel going to the left driver). Maybe you're talking about headphone connections showing more than 2 contacts on one side? Those can be a number of things depending on the type of driver, but it's not stereo sent into one driver.
For your specific case, I suggest you mention the headphone and perhaps show the cables in question, because there is a lot that could be going on depending on brands, or single end VS balanced cables.
