The 100% cotton Transformers Soundwave Costume T-Shirt would have helped you blend in seamlessly into the natural environment of the 1980s, but unfortunately nobody knows what a cassette is these days! Heck, I think people born after 1990 don't even realize that phones used to have cords and had to be plugged in and not just to charge them! *Shakes head* Any-who, the Transformers Soundwave Costume T-Shirt emulates the Master of Decepticon Communication and generally sneaky robot, Soundwave! Say, I wonder if they made him into an mp3 player these days to keep up with the times?
