Meta Quest 3s bluetooth LE-audio nonfunctional

Hi

I found out you can connect LE-audio bluetooth earbuds to Meta Quest 3s. My problem is, it doesn't work at all. It connects but everything becomes super laggy and no audio at all when LE mode is enabled in bluetooth settings.

I have Creative Zen Air Plus earbuds which supports LE audio when connecting to its' specific pairing name. When I do so, I can hear "LE connected... LE disconnected... LE connected... LE disconnected..." every couple seconds from the earbuds. Also everything on the Quest becomes like a 0.1fps slideshow until I disconnect the earbuds.

When I connect the earbuds with normal bluetooth mode, everything works fine. Only problem is that games have 1-2s latency in audio. Videos (Youtube etc.) don't have delay because they sync with the audio. 

Is the bluetooth LE-audio mode still early experimental or is it supposed to work as intended already?

Until it's resolved I can use wired earbuds with PD/audio usb-dongle. But then I lose smart funtionality of Elite battery strap. They charge the glasses fine but Quest settings doesn't tell how much there is charge left in the strap.

Edit: I purchased EarFun Air Pro 4+ earbuds and they work flawlessly in LE-mode. Creative Zen Air Plus uses Mediatek chip which doesn't seem to be compatible. EarFun uses Snapdragon chip which works.

At least that's the info I have been gathering from different sources. I hope this is of any help for anyone.

      So with the earfun you have 0 delay? I would be glad to ditch the Soundcore VR10 Dongle

        I wouldn't say 0 delay because bluetooth always requires packing and unpacking the signal. But it's definitely usable compared to regular bluetooth.

        I tested with a game installed on the Quest and the delay was barely noticeable.

        I also tested Steam game. I used Steam Link wirelessly. My PC is connected to Wi-Fi so that might affect the latency but I noticed there was slightly more delay on Steam than on Quest game.

        I didn't have chance yet to try wired connection on Steam so I can't say anything about that yet.

        LE-audio on Quest is still said to be experimental so it might get better, closer to zero, but that remains to be seen. At least for me it's totally useable now.

        Edit: I haven't tried Steam games with air link or virtual desktop yet. I will try to test air link this week how the latency compares to Steam link.

        Edit 2: I tested with Air link both with wired and wireless. They both have similar slight delay when using Steam VR than with standalone Steam Link app on Quest glasses. So for Quest games the LE-audio is suitable. With Steam games I'm still doing some testing on my own when I have time if there's any settings to reduce it to similar levels than Quest games.

        Edit 3: After tinkering with Steam VR a bit I think I found a solution that might work for me. When Steam VR is running, there's audio tab in settings where I can choose default output audio. I might buy cheap LE-audio dongle for PC where the earbuds connect when using Steam VR. That way I don't lose Quest audio when quitting Steam. Also the audio delay should be similar to Quest games because it comes straight from the source.
