For almost 4 decades 1/8" was a "just works" standard for interfacing consumer audio output from electronics. No fuss. More reliable than airpod pairing. Doesn't rely on battery life. No latency issues. Interference vanishingly rare.

Yeah, I can buy a dongle. Maybe I will someday when my original SE dies. Maybe I'll never buy an Apple phone again. But if I do buy a dongle, every time I will be cursing the person who took out the 1/8" jack.
