Apple has got proximity-based pairing nailed so well, it's easier than plugging a jack in. I can connect to other iPhones as easily as mine. Macs logged in to my iCloud don't need pairing at all. It works like it should, not like a typical Bluetooth crap.
The charging case is more convenient to carry than a bundle of wires. And of course I can walk around, zip my jacket, etc. without minding the wire.
It's more expensive, proprietary, it doesn't work well for some people. But I can definitely see why having AirPods Apple thought wired headphones are the next floppy drive.
