Yeah, but can it do Stereo Audio AND a mic channel at the same time?
If it can't, in 2025...fuck off.
This simple feature, is the reason why "gaming" headsets are still >$200
Isocronous Channels. It's been in the spec since 5.1 - 5.2. It's the same as with auracast. The spec can already do it, but no vendors are implementing it.
That is for bluetooth multicasting to multiple devices. Not stereo audio with mic channel. They STILL artificially limit you to EITHER Stereo Audio OR Mono Audio and a Mic.
Isochronous Channels is the underlying feature that enables both auracast and your headset use case. An arbitrary number of full-bandwidth audio channels, with or without synchronisation, with arbitrary endpoints. Why is nobody selling a headset that implements this? Fucked if I know, mate.
Can I have the features I wanted from 5.1 available in more devices now?
Like what? I only use BT for Android Auto and I'm otherwise oblivious to it so I'm asking in earnest
Broadcast aka "Auracast".

I heard about this stuff before it was released and I was like "Wow that's so cool! There are so many applications for it!" But since then all the device makers have been like "Wow that's so boring, I definitely don't want to use that - or if I do, just use the name for some marketing bs but never actually implement it properly"
