Instead I have to buy the shitiest locked full of crapware android phone and hack it with an LLM to make it usable because apparently that's what I deserve for wanting a headphone jack.
Best of both worlds.
The DACs/amps you linked are bigger than the Sony mp3 player I had in 2004. It had two jacks and a user replaceable battery. And it was water resistant.
I could go on and on.
Take care!
