They don’t call them “mp3 players” anymore - that may be why you can’t find what you need. Look for a “DAP” instead - digital audio player - and you’ll probably have more luck.
For example, the Fiio M7 is $200 and is pretty full-featured. I have the M6 and I think I paid around $100, but I don’t think it’s being sold anymore.
