Swap the batteries, tips, charging case, shell, or even just individual buds.
But of course we all know that the big manufacturers don't do this not because they can't but because they don't want to. Planned obsolescence is still very much the name of the game, despite all the bullshit they spout about sustainability.
This the type of business the EU has to develop. An entire ecosystem from phones, earbuds to computers and software. It's how you create a conscious and a model.
Unfortunately most people don't care. And since they don't care, they don't buy. These earbuds cost 150€ because they can't afford to buy huge amounts like Apple. I wish they could lobby the EU to subsidise these kinds of devices.
