Nothing authoritative but I just read an article asking why Apple didn’t switch the phones over to the usb-c connection that they use in the computers so that there would only be one cable/connector needed. The conclusion was that it was likely Apple was going to ultimately go connection free very soon. I sure don’t see the headphones jack coming back no matter how nice that would be for use old timers.
I have the Apple AirPods and I love them. But, when I make an important call, I plug in my wired headphones. I just trust them, plus, the volume is right there handy on the wire. Yes, I have an iPhone 6. Bought it last year and I hope and expect that I’ll get another 3-5 years out of it as long as they don’t technologically kill it before then.
