Cassette shaped MP3 players is nothing new, but this design concept immitates more than just the design. The point is to bring back the feel of cassettes and that means the players will only hold 45, 60 or 90 minutes of music – something which would probably translate to 96, 128 and 192 MB.
The concept player will only play back files one after the other, no skipping tracks, to give that authentic feeling of a cassette. You can fast forward or rewind using one of the spools, and the other spool will let you charge the battery by turning it. Cases will be shaped like cassette covers and transfer will be done via an integrated USB plug. Since it’s only a concept it probably won’t make it to production but it’s certainly an interesting design, especially with the cassette imitation features.
