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.
You can get 3.5mm to (whatever usb port) that will as far as I know work in every phone. Just because it doesn’t have a dedicated port doesn’t mean you can’t wire in your headphones.
I much prefer it this way, if you want to wire you can, if you don’t you don’t have to have an extra useless port on your device.
Edit
Lol, bring on your down votes. I bet if you surveyed a hundred random people on the street if they really want a headphone port on your phone and are committed to using it you’d get less than ten people. It’s not realistic to support every legacy hardware function on a modern device because a few tech enthusiasts want it, especially when there’s a very easy way to support it.
You’re supposing every tech/audio enthusiast here wants the same shitty setup as the masses? The fact is there is basically one brand still offering headphone jacks in a flagship that you can unlock … where the point of Android was all the delicious innovations of each OEM. But they saw how profitable selling branded earbuds could be so now you have next to 0 options.
