My needs isn’t more important than anyone else, but I wanted to point out the selfishness of the oposite point of view by making mine as selfish.

There’s nothing selfish here. Keeping the jack benefits everyone except Apple and other BT headphone OEMs. It doesn’t hurt anyone else.

has no advantages over a dongle

The advantage is that you don’t need a dongle…

and it inconveniences

There are none

could easily be overcome by simply adding a second usb-c port

Still requires carrying a dongle or buying a pair of headphones that only works with phones and computers, and not the vast array of other devices that still use headphone jacks, new and old. So that solves absolutely nothing. As I said elsewhere, we’ve created a competing standard, for no reason.

you’d be able to do far more than you’ll ever be able to do with a 3.5mm jack

What? Do you think we’re suggesting removing the USB port? What are you talking about?

And it would take you 5min searching the web to get good review about usbc DAC with actually good sound, even better than any internal DAC.

I don’t want to search the web. I don’t want a DAC. I just want to plug in my headphones. This is absurd.

It cost a whopping… $10.

$10 to buy something that previously cost me $0. Only it’s inevitably going to get lost so you’d better buy a half dozen of them and replace them every few years, so you’re looking at dozens of $ per year for something that was previously completely unnecessary.

As for the precise number…I’m not in that field, I do not have access to them

Yeah, I didn’t think so.

and if they don’t bother adding that port back, they are most probably basing their decision on them.

No, they’re basing that decision on the same thing everyone else is: money. Greed. Much like Apple they also released their own bluetooth headphones at the same time as they removed their headphone jack. But I suppose that’s just coincidence, right?
