Vintage AUDEX headphones from FRANCE

Description

These vintage headphones made by AUDEX seem to be in beautiful condition.  Note that the connection is likely to go through a projector of sorts.  This headset came to me from a friend who had a great interest in early film projectors and related 16 and 8mm cameras.  Happy to try to answer any other questions as I can.
I have dusted away from small specks from within the ear covers and assume that there is an older foam piece that is aging badly!  I did not to try to open the ear pieces any further; I will let you do that when you get these home.
For an overseas buyer, I will ship for free to the eBay Global Shipping center, and the buyer will pay the expenses beyond that.  US Shipping will be as per the USPS.
