This is a vintage 'Telephonics' Audio/Radio Headset. Nice metal spring-loaded ear cup adjusters. Comes with 1/4" cables and plug-in cable leads. This particular model was approved by the Railroad Industry for noise reduction. They were used in a frequency rage of 4-8000Hz. Due to the accuracy & range, this model was used for extensive studies on autistic & hearing impaired patients. This is a great collector piece.
