In Supernatural episode S10E19 this past week, Sam is using a Phillips reel to reel with a set of headphones. Given that they are in the men of letters' lair, likely the headphones are supposed to be from the 1950s or so. Are these a known brand of headphones? Or perhaps are they headphones that came with the Phillips reel to reel.
