I'm not saying they are, but phone connectors.. aka "Aux ports" were designed in 1878, with the 3.5mm rendition dating back to the 1960's. It's obsolete tech. We can easily be making headphones with connectors that are a fraction the size. There's no reason USB-C and lightning ports shouldn't be multi-use. One port, many applications.
We have gone from one standard interface, to now three interfaces (headphone jack, USB-C and lightning), and one of them is proprietary.
We move from a world where you can buy any set of headphones, and use them with any device, to a world where... nothing is compatible with anything else. Either you use a permanently connected dongle, or you buy multiple sets of headphones.
The future is stupid and I don't want to live in it.
