Best phone for local wired audio

Because I will lose my shit if I get pushed into one more subscription I don't want or need I've decided to abandon each and every one of them all together. So Spotify has to go as well. To find a replacement for listening to music I was looking at a DAP, but I've realized that having a seperate device just for music playing will probably end up not being used. But i am intrigued by a jump in audio quality and liking the idea of downloading my music again.

So I am looking to move away from my 10 year run with iPhones and change to a phone with a headphone jack that supports high quality audio. For this i would need an SD card slot. I don't mind a phone being a couple years old since I don't care about the latest features. I just want a phone that is new enough that it will work well for the coming years. I saw the ROG phones, but honestly the whole gamer aestetic is not for me. Also I read some thing that Sony's DAC's aren't even produced by them anymore? If anyone has a nice suggestion I would love to hear it :) Thanks in advance!

I also want to invest in some nice earphones (can be IEM's), but I do want them to be portable enough so they aren't an obstruction and can be put in my chest pocket etc. So if anyone has a recommendation for that it would be greatly appreciated.
