This is a switch box produced in the late 60's to allow listening to TV sound using old-style magnetic headphones. Should work with newer headphones, but no guarantees there.

Comes with original slightly tattered box and instruction sheet.

Buyer to pay actual USPS shipping from 93430. No bogus packing/handling fees. Switchbox will be carefully packed to avoid damage during shipment. Please email with questions; all auction sales final. Good Luck and Good Bidding!
