Actually it’s even older. And it’s also not used in a phone.

The argument that 3.5mm jacks are somehow superior to a digital stream is so laughably flawed. The 3.5mm jack is a shit connector, always has been. It got its success from being paired with the original walkman, not exactly hifi equipment. The durability of the jack is wanting and a few specks of dust in the socket and you’re getting static when you move about.

I don’t know how many sockets I’ve had to replace over time because a male jack broke off in the socket. It’s one thing that the jack is so thin that it can break in your pocket. But when manufacturers then mount sockets, that doesn’t allow you to push the broken part out, and also uses some weird one-hung-low socket with a weird footprint that you can’t source with less than a 5k MOQ, and that is only after searching for an hour. Which then leaves you having to do all sorts of weird cowboy tricks in order to have a working sound output… Then you will get to my level of annoyance with the 3.5mm jack.

All those problems are not really a thing with 6.3mm jacks, but, by all means, keep believing that 3.5mm is superior because professionals use something that looks like it, and disregard everything else.
