I use my phone as my primary music player, too — both at home and when traveling. I have a nice (Mass Fidelity Core) Bluetooth speaker for home, but for travel, I dropped a couple bills on a nice pair of wired noise-isolating earbuds (B&W C5 S2), and having that purchase unilaterally obviated remains a sore spot for me.

Yes, I could drop another $40 to get that functionality back, but then I sacrifice simultaneous charging. It's hard not to see this as being pushed around by a bully who's after your lunch money (for arbitrarily large values of "lunch money") sometimes.

I'll stick with a 6S for as long as I can, and hopefully this situation will be resolved somehow before then. Maybe they'll release another SE-like device that has a physical headphone jack again, but I'm not holding my breath.
