You should research a bit more on a couple things...
Face ID while not perfect is much, much more secure than Touch ID.
But you are correct that wired audio is still a bit better than Bluetooth, but with 4.2 and 5.0, these days I can barely tell any difference (I’m an actual audiophile) my vision is not great, but my hearing of subtle variations and issues with sound is something I use everyday. My main issue with certain Bluetooth (mostly anything before BT 4,) is those devices have some slight humming noises, syncing issues, and distortion compared to wired audio.
But, like I wrote before, BT 4.2 and 5.0 have increased their quality drastically, so much that I can barely tell any difference. Soon BT will be equal or (I dare to say it) superior to wired (not in sound but convenience.)
Also OLED is a technology that looks great but the cons outweigh the pros. The longevity is much shorter than LCD, pixels die faster, and are more prone to damage, the price is way too high still, it isn’t as durable when it comes to water damage, and image retention is still a major issue and super annoying.
