I stumbled on this the other day. It looks stupid as hell but it’s actually a pretty dope idea. What you do is take a SD card like you use in a phone or a camera and load it into the Cassette. Then you can pop the tape in your car, stereo, Ghetto Blaster, whatever and it works just like a regular tape. You can also plug headphones into it and use it like a regular mp3 player. I think it’s only available for wholesale direct from China right now, but i’m sure somebody will bring it over to the U.S. soon. Check it out here.
