No, the purchase was for the reason that my phone doesn't have a headphone jack, even though I could just have gotten an adapter instead. I obviously do not have the new iPad, it's impossible since it isn't out yet. My current iPad has a headphone jack. My phone is a Pixel and I still got the Airpods 2 since they are among the cheapest good quality bluetooth headphones currently on the market.
Your argument that people who really want to keep using wired headphones would purchase an adapter for the iPad doesn't work well, specifically for the iPad, because of the mentioned issues. The conclusion isn't that it's good to remove the headphone jack in its really broken state, Apple should instead fix their iPadOS volume issue and make the port work with high impedence headphones like on the Macbooks.
But instead of improving the port to work with a wider range of headphones, Apple decided to put zero effort into it and just remove it, then demand extra money for an adapter to restore this broken state. We know Apple can make a good quality headphone jack because they currently sell it with their Macbooks where I have no issues with any of my headphones.
And from that I conclude people who want to listen to music with high quality headphones won't get the adapter to begin with, and anyone else who doesn't care about wired headphones anyways will just get Airpods. iPhone users don't buy the adapter. Everbody either uses cheap Airpods or doesn't connect any headphones at all. Occasionally there will be people who have other bluetooth headphones, but it's just a matter of time before they die. They'll eventually try the Airpods and realize they're really decent. (They're still trash when the battery inevitably dies but at least they'll last a couple years.)
Exactly. The removal of the jack was a way to make wired headphone more inconvenient on mobile devices (a dongle is always more inconvenient despite what some here try very hard to deny and if you need to charge the phone at the same time you are out of luck and Apple does not even sell a double duty adapter).
But AirPods are a better solution than wired headphones in most cases (which are more inconvenient even with the jack, although cheaper).
My main phone is a Samsung and still has a jack (the S10 series was the last to have it) and despite that I use airpods 3 with it.
And all my laptops, desktops and tablets have each their own airpods or Samsung equivalent (I have tons of them, since I have tons of devices, just airpods I have 6) because again it's a superior solution.
The main situation where I use the jack is to play the piano since bluetooth has latency and also, to be honest, the quality of some high end Sennheiser is superior to airpods.
But that does not mean that the jack is irrelevant, it's something I do appreciate the few times I need it. And sometimes it has been a life saver.
All the excuses for the removal of the jack (takes space, battery, water resistance etc.) are just that, excuses. And some small phone manufacturer show it by making phones, including small ones lile the Zenfone 9, with a good battery, water resistance and a jack. But basically all the companies that sell wireless buds have removed it. It's basically become a selling argument for those small OEMs who don't sell earbuds. But the jack is here to stay for a very long time in laptops (except the stupid Microsoft that removed it from the Surface pro 9).
