I’m starting a running program with my family. Part of the fun is building a shared playlist and listing to cues together. I’d like to run the audio off one phone and have it go simultaneously to 4 headsets. I see there’s phone apps that do today but my kids don’t have phones. Is there a hardware device that can do this?
If its a laptop, yes. I was only suggesting it in case someone else finds this post later and finds it a suitable solution, I dont think it’ll work for the OPs use case.
