Some of us in androidland continue to buy phones specifically because the headphone jack offers a quality of life improvement more than whatever other features are offered in place of the jack.
I also have bluetooth headphones, but I prefer not having to worry about battery, prefer the sound quality, love the simplicity (pairing doesn't exist), and enjoy the utility (can plug into anything with an aux cord).
I can justify any inconvenience. I can justify additional expense. But in this case, I choose not to. If you choose to justify the inconvenience, that's on you—but acknowledge that it exists.
