@Alexbbrown I meant using the shared audio feature of AirPods. The audio sharing wasn't the issue though since that's much improved over using a hardware splitter with the shared audio feature 🙂
The issue is using a single iPad between the two of us for the same content.
Ideally, what I wanted was to be able to watch the same content on two devices (without WiFi, so SharePlay might be out .. though I'm still looking into it) and have the playback synced. This should also lend to being able to use devices like the XReal glasses to get a much bigger screen/display but still have synced playback ... At least, that's the dream 🙂
I know this is a long answer for the headphone question 😛 As far as headphones go, our current solution only works for two. But the solution I'm working on should work for more than two as well ...
