yeah sure not having a wire is nice, but two generations of earbuds from my phones own manufacturer and both pairs i get regularly dogshit audio quality, and half the time one of the buds doesn’t even work or produces barely any audio. There is no way to remedy this even after resetting the buds and the bluetooth connection. and you have to shell out 3x as much money for these things. also it’s yet another device whose charge you have to keep track of
“bluetooth-only” not the mere concept of bluetooth. phones before 2016 could still do all the things you mention.
also wifi is a pretty bad analogy tbh. not only is it not nearly as shitty and unreliable as bluetooth, but the typical use case is way different. listening to music from a device in your pocket or hand to speakers in your ears is pretty different from running ethernet around your house (and if even a small amount of effort is put in you could run ethernet around your house in such a way that it isn’t in the way, even if ugly. if anything the cost is more prohibitive than dealing with a bunch of cables)
