To be clear I know what multipoint is and it’s not what I am looking for. I don’t want to toggle between two audio sources. I want to combine several various audio sources into one set of headphones. I searched online for this and a lot of people were asking why someone would want to do this. It’s so I can do things like play Elden Ring on my Steam Deck and listen to a podcast on my phone. Zoomer stuff.

One way I’m pretty sure I can do this is with Bluetooth audio receivers, a X in 1 out audio mixer, a USB hub and power source, and a Bluetooth audio transmitter.

I am not sure if using the same cheap audio receivers would cause issues or what kind of latency that would produce. Given how many people use Bluetooth headphones these days and the existence of Bluetooth DACs I thought something would exist (even if it was limited to a niche Tindie product). Ideally something that makes the pairing process easier than using screenless audio receivers and is a bit more portable.

I would appreciate any tips or suggestions to simplify this setup.
