With completely wireless earbuds, the rule is: when the battery fails, they have to be disposed of. Not so with the Fairbuds, that allow you to replace batteries in just a few seconds. Combined with a repairable design, the earbuds should therefore have an extremely long lifetime.

That’s the beauty of usb, it’s capable of expanding to suit your needs
Simply put, if companies determined the market need for 3.5mm port was valuable enough they’d leave it on there. They want to sell product and 3.5mm is not a feature enough customers care about to justify it’s existence. If you really want it, you have USB options or some phone models that support it: https://www.phonearena.com/news/Best-phones-with-a-headphone-jack-Google-Pixel-Samsung-Galaxy-LG-and-more_id124459
The reason it’s not “valuable” is that they want to force people to buy expensive earbuds every year when they crap out. This is demonstrated by the fact that none of these phones that have removed it have added anything new in it’s place and they’ve only gotten more expensive. Practically every phone on the market is just a copycat phone, camera, social media browsing device. Maybe a few have a stylus. The only thing that differentiates them is specs. My 6 year old phone has more features than anything available today and I dread finally reaching the point where my work apps stop functioning due to it’s age and I have to downgrade to some garbage that can’t do half the things I used to.
If you buy crappy headphones they might crap out every year. I’ve got the same pair of Jabra 65t that I bought in 2018 and they work amazing 6 years later. If Apple or Samsung or Google forced you to use their buds I’d agree with your position of being forced but they don’t and saying all buds die in a year is absurd.
