Bluetooth's downsides: * Pairing UX is unreliable and has corner cases that even Apple hasn't solved and they're probably the best case. 1/8" is predictable and reliable (and doesn't require extra thought / kit to make sure you can power at the same time). * Battery life isn't an issue for wired headphones. * Latency is unacceptable for some use cases (mostly specialized audio), and sometimes audio quality is degraded too. I like wireless audio, (especially for workout listening) but I miss the headphone jack on my original iphone 5 SE at least once a week.
