I’m sure Amazon has enough actual customer data to make their product decisions based on what moves the most volume.
And the reason most phones keep these is because wireless headphones are in the end luxury. They're not necessary, they're not even significantly better, but they're in the end a class symbol.
They don’t sound better, but if you care about sound quality over ux then you’re even luckier nowadays than any time prior because you can plug an amp/dac into your phone
1. The user whose jabra headset is intermittently cutting in or out, or whose airpods are empty, who then switches to macbook speakers & microphones
2. The user user whose left airpod is still playing music from the iphone and only the right airpod did the handover correctly
3. The user whose airpods manage to noise cancel his own voice away
And this isn't every now and then, I see at least two out of these three users every single day. No matter which company, which client, every single day, for years. This is not an exaggeration, it's absolutely maddening.
And honestly, I don't care about the cable tangling or snagging if it at least reliably works.
Then there's the other issue of latency. Wireless headphones, even airpods on MacBooks, have horrible and unpredictable latency. The OS tries to hide it from you, but if you're doing live video/audio/broadcast, they're absolutely useless. I do volunteer work in that field, and over the past years it's gotten worse and worse with volunteers bringing wireless headphones, which they can't use for critical audio/video work.
And honestly, I don't care about the audiophile grade quality, we had good enough quality for free in every device, there was no reason to remove the 3.5mm port. Every current-gen midrange phone still has them, and Sony even keeps them on the flagships (which is why I buy Sony, and recommend everyone else to do so as well).
It's great that the best-case scenario is better. But like with FPS, the experience is primarily determined not by the average, but by the 95th percentile.
Also I think the more serious issue is the SD card slot. The missing headphone jack is annoying, but you can work around it with an adapter. Not so for the card slot
Obviously, both of them are absolutely silly "solutions" to problems that wouldn't have been necessary in the first place.
You certainly can't realistically keep an SD card dongle permanently sticking out of your phone to store your photos/etc.
