Is it possible to add a 3.5mm headphone jack to a pair of antique crystal radio headphones?
I am looking to purchase a pair of antique headphones, and possibly fix them up to work like a new pair of headphones. For example, would it be possible to manipulate these headphones, and add a 3.5mm headphone jack to them?

Thanks for your help.

I think it would. They are not stereo as built -- the +/- terminals are simply split to provide identical +/- signals in parallel to each earpiece.
In terms of maintaining the integrity of the piece, you might want to just build an adapter to plug the existing end terminals, with a 3.5mm jack on the other side.
Since the leads inside each earpiece are on screw terminals, you could even remove the entire lead assembly and wire up a modern 3-lead stereo jack (common negative, left+ and right+).

I've done exactly that with an old set of monaural, aircraft headphones.
