I'm guessing that if MP3 players had been invented in the 1980s, they would look something like the Retro Mobile MP3 Player from USB Brando. This MP3 player is modeled after a cell phone that time forgot.
The Retro Mobile MP3 Player is so much more than a 1980s knockoff, however. This MP3 player can play music from an SD card or the radio, and it even doubles as a portable speaker. Now you can finally listen to your old Don Johnson songs the way they were meant to be heard. You've gotta love the 80s.
