I seem to remember reading something about aptX LL needing some special transmitter support? If so, not sure if that might prevent aptX LL being added, but I hope I'm wrong.

I got a T10P, but the 'button' seems to do nothing no matter how I press/hold it, so thinking it may be faulty. I somehow got it to pair once with a pair of headphones, but can't do much more - unless I'm somehow missing something obvious.

My KB9P seems to work fine on Windows 11, haven't had any issues so far.

With the KB9P (and possibly other models), does anyone know what the 'PS5 high volume mode' actually does? The description just says 'double volume' but the instructions make mention of the microphone.

They clearly linked it. Here's another quote from their link: "LC3 is being introduced with LE Audio, and support is mandatory for all LE Audio products". https://www.bluetooth.com/media/le-audio/le-audio-faqs/

The quote they already posted from the FAQ literally says "mandatory".

Can anyone confirm whether, if I had a KB9B (or other KB model?), and saved the codec and Adaptive quality/latency settings with the app, if the settings then should stay that way if I was to then take it and use it in a different machine (or console) without the app? Thanks.
