Well good luck then. Because enough of us have absolutely no problem with using the usbc or Bluetooth. I rarely even listen to music anymore anyway so it's not something I use.

Companies removed it to sell overpriced wireless headphones.

Of course, I'm not denying this. That still doesn't negate my point about audio jacks being redundant ports.

It’s way better to use regular headphones than the wireless pieces of crap with batteries and an amplifier and a bluetooth receiver in them.

Yes, and those regular headphones CAN be plugged into phones without headphone jack via the USB-C port

Also, just because people have “switched” to wireless doesn’t mean that they don’t have a pair of old wired headphones still lying around somewhere, unused, eventually turning into e-waste.

Another use-case for the headphone jack: I use it to connect my phone to various audio devices, e. g. E-drums for practising playback or the practice room PA tolisten to demos. Nearly all professional equipment uses wired connections.

Citation needed.

I don't have a source ready with me to back up my statement. But at least here in India, almost everyone I see in public transportation use wireless earbuds. Usually I look like the odd one out for wearing wired earphones.

If people already have wired headphones, then the most eco-friendly solution would be to enable users to continue to use them, and not force them to buy even more new products.

You absolutely don't need to go out and buy a new headphones if your phone doesn't have an audio jack. Just buy a dongle. Yes, I'm aware that this is worse for the planet than just including an audio jack in the phone. But if you buy a dongle once, you don't have to worry about your future phones not having a headphone jack. So in the long run, this move is better for the planet.
