They're viewed by everyone as superior in hindsight, but anytime anything gets taken away there are vocal voices complaining about how the newer alternatives are inferior in various ways (and technically the newer options are always inferior in certain ways, especially in terms of using them within existing ecosystems and usage patterns).
That is completely untrue. No one got rid of the floppy drive just because new technology existed. They got rid of the floppy drive because it took dozens of floppies to do what one CD could do. It was a genuinely inferior product with regard to its primary function.
In the case of headphones, their primary function is to connect to a device and deliver sound to your ears. Wireless headphones do not do this better than wired headphones. At all. They have a specific use case advantage related to the connection format, but that isn't universally better because it carries drawbacks as well.
