Head/earphones with built in MP3 player

[Red Storm]

Does such a device exist and has anyone here used one? Don't want to deal with cords or having to carry around my phone or an actual MP3 player, and I'm not interested in wireless/BT headphones as that still entails carrying around a separate media player.

I had an old school one, once upon a time. Sucked balls. That was like 10 years ago though.
