- Chapter 113: The Man Who Crossed the Atlantic
Joseph's Walkman is initially a Sony WM-701C at the end of Battle Tendency and Stardust Crusaders. It is black with a slim, sleek design and a compact rectangular shape. It has an integrated remote control and headphone socket. The top has buttons for opening, locking, and stopping the music, whereas the side has a volume slider and buttons to change tracks. Compared to its real-life equivalent, the headphone socket and buttons on the side are reversed.
In Diamond is Unbreakable, Joseph uses a Sony MD Walkman MZ-E3 instead.
Joseph uses the Sony Walkman while boarding a plane to Tokyo at the end of Battle Tendency, listening to a cassette by The Beatles.[1][2] In Stardust Crusaders, he inserts a Get Back cassette into the player.[3][4]
A decade later, Joseph upgrades to a MiniDisc Walkman.[5] It is omitted in the anime adaptation.
In the Stardust Crusaders OVA, Joseph is shown listening to the Gipsy Kings instead of The Beatles.
Around 1987-1988, Joseph has a long conversation with Lisa Lisa. While heading to the airport to drop Suzi Q back home, he listens to a cassette of Ben E. King's songs, which he had recently grown fond of listening to.[6]
In the original Weekly Shonen Jump publication of Chapter 113, Joseph mentions that he is listening to Get Back by The Beatles on his Walkman. The name of the song is omitted in the volume release as well as the TV Anime, but is still present on his cassette at the end of Stardust Crusaders.[7]
Joseph's Walkman was drawn by Hirohisa Onikubo in the last chapter of Battle Tendency. Hirohiko Araki purchased the same Walkman model for Reki Taki as a bonus at the end of 1988, which Onikubo referenced for his drawings. The earphones and cassette tape inside the Walkman also have the same appearance as what Taki was using at the time, although Taki wasn't listening to The Beatles.[8]
Joseph's Walkman appears with Joseph in a commemorative SSR unit in the mobile game Stardust Shooters. When the unit is equipped, the background music will be changed at the beginning of the round. The unit is unlocked by completing Battle Tendency on Easy difficulty in the Story Mode.
