I don't think I've ever had a more satisfying music listening experience than my original iPod Shuffle, the white stick one which plugged in directly as a USB drive. The simplicity of the switch on the back that toggled between shuffle and non-shuffled modes was perfect. I could load up around 300 of my favorite songs (which, as a high schooler in the heady days of Kazaa and ilk, was about all I possessed), know exactly what I was going to get, and could play hunt-and-seek by toggling between my known playlist order and shuffle. And that was it! No screen getting constant notifications, no navigating through ever-changing hierarchies (looking at you, Music on iOS app), and I didn't even need to be OCD about album art at that point.
Ah, the glory days... :)
This this $21 screen-less MP3 player looks interesting: https://www.amazon.com/dp/B0722KVJM3/
First result from an aliexpress search for "mp3 player":
Their only weak point is a bit of background noise at low volumes, but for the price they are amazing.
The audio quality is pretty reasonable and it'll happily play MP3, WAV, FLAC, etc. The battery whilst on wire is amazing, whilst on Bluetooth you'll get about a day.
As the article suggests, one of the reasons to use this over a phone is to save battery life. You also get a completely dedicated device encase you are charging your phone and want to go for a walk, or are exercising and only want to carry minimal equipment.
If I wanted to listen to music while coding, I found a workaround by owning a Shuffle and getting approval for it. The Shuffle doesn't have a USB port and doesn't connect to WiFi or Bluetooth, so it met all the criteria for an exemption.
It's weird having lived in such a strict cross-section of users to need these specific criteria met. Even the OP lists several options that all would fail to meet these restrictions.
Has everything apart from streaming from your phone, but does sync and download new songs over wifi, and play over bluetooth or a headphone jack..
I suppose Apple Watch or some other Wrist Band like are sort of a replacement if you are looking for smaller portable music player that is not a bulky phone?
[1] Now MP3 is patent free, even AAC-LC is patent free. How time flies.
But I think a lot of people have mp3's. When I read about ripping cd's to something it is usually mp3 or flac that is wanted.
Some of the best/classic MP3 players are only available as refurbs or new-old-stock.
