Making a Bluetooth alternative, I think apple is the only company that can pull it off. But they will absolutely do it such that only their headphones will work with Apple devices. And then they will license other manufacturers to be able to use their tech to connect to apple devices.

Otherwise, I see a huge opportunity for a consortium to develop a new hardware and software stack for high quality low latency audio and being them as a package to their products. I would love a completely wireless Dolby Atmos like setup with no central receiver, your mobile device itself being the av receiver. New speakers from any manufacturer and form factor could be added wherever you want as you buy them. Calibration according to your speaker placement would be wireless and automatic.
