Some devices suffer from an identity crisis. Like this guy, the USB Cassette MP3 Player. It’s designed to look like your run of the mill outdated plastic cassette, and is even the same size, so that it fits into your vehicle’s cassette deck (assuming you still have one) for portability. It also sports an SD memory card slot that holds all of your songs in flash memory.
Just drag and drop to transfer your files from a computer. The memory size is only limited by the size of your SD memory card. It will cost you $22 and has all of the usual buttons to control audio playback and volume on one side. So is it just an updated cassette or an MP3 player?
