I happened to be looking for a similar portable music player / conference call headset recently.
My process was to first identify a close-enough product using a search engine like Google or Amazon, and identify the relevant search terms (in my case, "portable DAC Amp". Then, if possible, I'll find a specialty forum for that product niche, and read user reviews there and on Reddit, Amazon, AliExpress, and/or blogs and dig into products that users compare it to or suggest as replacements (or use "$PRODUCT vs" search queries and see what shows up on top).
Then finally read the product manual. This is a very manual and time-consuming process. Or you could just ask here on HN :)
For your requirements, I'd recommend putting Rockbox onto something like an iPod:

[X] Plays from filesystem
[X] Support OGG, FLAC, other file formats
[X] Equalizer
[X] Shuffle, Fade, etc.
[X] Open source firmware
For my particular use-case, the objective criteria were slightly different:
[X] lightweight / has a clip: 25g, metal clip
[X] high quality audio output via audio jack, that can drive a headphone
[X] move the bluetooth antenna farther away from my head: https://news.berkeley.edu/2021/07/01/health-risks-of-cell-phone-radiation/ https://news.berkeley.edu/2021/07/01/health-risks-of-cell-ph...
Since I use a phone for media storage, I dropped the "plays from filesystem" requirement, and can play virtually any audio format using apps.
- Fiio BTR5 (get 2021 or later version for better Bluetooth range):
[X] Display
[X] Easy to use interface
[X] equalization, but EQ does not work with LDAC codec
- Qudelix 5K (if you can drop the display requirement)
[ ] Display
[X] Very powerful/configurable app
[X] equalization with LDAC codec
