This! I have my headphones paired with my laptop and phone. When ever I power on my headphones it automatically connects to both, but I only get audio from which ever of those connected first. If it’s not the one that I wanted then I have to go to the other device and manually disconnect the headphones. I was hoping to just hear the audio from both at the same time, but maybe that isn’t working because my laptop bluetooth only supports 4.2. Either way, if the headphones can connect to both at the same time, but can only play audio through one or the other it seems to make sense that you would have a way to switch sources.
Normally both are right next to me, but yesterday my laptop was in the living room and I had just settled into bed and wanted to listen to a video on my headphones. I turned them on, and it connected to both devices, but my laptop was the only audio source I could hear. I had to get up and go to the livingroom and disconnect the headphone from my laptop so I could hear audio from my phone.
I also want to use my headphones with my TV sometimes, but Android TV doesn’t have a “disconnect” option (or at least mine doesn’t) only “unpair”. So if the TV is the audio source that the headphones connect to, then the only way to get audio working from my laptop or phone is the unpair the device. Even if I could disconnect it’s still several menu options deep and cumbersome to navigate to.
EDIT: So i’ve just noticed that when my laptop and phone are connected, that both can play audio, just not at the same time. If audio is currently playing on one device the other device simply will not be heard.
For example: If my phone is playing music, then i’ll never hear audio from my laptop until I stop it. If I make Windows make a sound and press play on music on my phone while that sound it playing, my phone will play the music, but I can’t hear it. After the Windows sound stops, if I stop the music and start it again I can hear it. So basically any source that starts while another is already playing will not be heard.
