From HandWiki
Astraltune, also known as the Astraltune Stereopack, was a personal stereo player created by Roy Bowers that appeared on the market in Reno Nevada on September 1, 1975.[1] The tape deck fit into a padded sleeve and was worn on the chest using a harness. The headphones hung under the chin rather than over the head. Controls were protected by a zippered flap that faced upwards.[2] Astraltune filed for trademark in 1978 and patent in 1980 but were denied.[3][2]
