I’ve been puzzling over this: why didn’t the phone’s manufacturer give it the ability to act as a Bluetooth receiver?
I’d happily lie on the couch and watch a movie through my favorite wired headphones — without a cable running across the entire room.
I’m hoping to find some app that can at least receive audio over Wi-Fi. But Bluetooth would be more elegant and more efficient.
UPD from 2024#
Roku TV has a somewhat similar feature: you install their app on your phone, and the TV routes audio to it — I’m not sure how exactly, whether over Wi-Fi or via the internet. But in the general case, the problem still has no solution.
