You can still buy 'em on AliExpress for example (I got the RUIZU MP3 player without a screen for 20€). If you are a sound nerd or hifi enthusiast you can get one that connects to a Bluetooth DAC (like the fiio for example) for super sound.
It’s kind of quiet in a way to just push play and knowing exactly what you’ll get (no hiccups, no commercials, no “you maybe’ll like this new song Spotify stuff”…).
