This is like the old school airplane earphones, I love it !  And there is one on Ebay:

BTW, be sure to watch the item before buying, the seller offered me $20 off.  I suspect the seller would accept a lower offer.

I looked in the 1964 catalog but Lafayette had dropped Pioneer as a vendor.  I didn't see any Pioneer items in the 1963 Allied catalog either.

A megaphone (sorta like a horn) is mentioned at about 24:15 into the video but really, watch the whole thing, it's always worth the time IMO.
