Manufactured by Koss Electronics in 1966, based on their landmark SP/3 model, these blue plastic mono headphones with Beatles earpiece graphics hold a notable distinction: the first-ever signature headphones sold commercially. Licensed through FOMISA in Lugano, Switzerland, they retailed at $29.95 and were marketed to retailers as “The Beatles Own Listening System” — pitched hard at teenage record fans and young musicians alike.

The Beatles made history in 1965 as the first pop group on a metal lunchbox, per the Smithsonian. Aladdin Industries’ aqua-blue “blue” lunchbox and matching thermos, produced 1965-66, used Dezo Hoffmann photos reworked into embossed portraits by artistic director Elmer Lehnhardt. A vinyl “Brunch Bag” alternative and a rival Air Flite version also hit shelves — but the original metal-and-thermos set remains the holy grail collectors chase today.
