Well we can do gigabit wifi that can stream 4k Netflix to several screens at once but they're trying to squeeze the tech for audio into objects the size of airpods, batteries and drivers included. To be honest the hifi community hasn't truly pushed for the wireless space and so it has been optimizating for consumer products, but really the technology is there. It may or not be Bluetooth that does it but the non-blueooth options all still have problems for some reason. Eventually the shit's gonna click.
