When the Sony Walkman hit the market in the 1970s, it was the first time we were able to take our music with us on-the-go. I explore this iconic piece of tech—from the inspiration behind its compact design to how it changed portable audio forever. I also enlist the help of fellow YouTube creator Judner A.K.A. Uravgconsumer to fix a busted Walkman. The Gregory Brothers join me to test out whether a vintage Walkman is durable enough to survive a game of ultimate frisbee.
