That's one of the core annoyances of Bluetooth: it's 1:1, not many:many. I've got a desktop, a laptop, and a phone. I've got a Bluetooth earbuds (with microphone) and a Bluetooth speaker (no mic). So obviously it should be simple to play audio from any of those devices to both the earbuds and the speaker at the same time. With wired headphones & speakers, that took a $2 splitter. But with Bluetooth, at best you can get one application per output. It'd be really nice if you could play audio from multiple sources to the different speakers at the same time. But that can't be done. You have to disconnect from one device, connect to the other, each time. I've never even seen a Bluetooth mixer (not a wired mixer that can use Bluetooth, but a device that can manage multiple Bluetooth connections for different audio streams at once). The same stuff all applies to Bluetooth microphones. Bluetooth needs many:many audio streams to get parity with wired sound.
