I purchased these little used headphones when I was i the Service, probably used them 5 times and they have been in storage the past 50 years, they still sound great and almost look brand new.

The Model SE-50 are 2-way stereo headphones of the highest quality, employing a 3" cone-type element for reproducing rich, dynamic bass and a horn-type element for subtle, clean highs.
As a novel design for stereo headphones, volume controls are provided on the earpieces for controlling the volume of sounds on each channel.
This newly added provision permits you to freely control the volume of reproduced sounds in complete balance of the right and left channels.
As a level control attenuator is provided for the horn-type element, you can control highs to your taste or to the kind of music you listen to.
The headband is designed on various human engineering considerations including wearing comfort, ease of adjustment, ease in operation of the level controls for highs as well as of the volume controls.
