Apologies if there is a thread on this already.
So, I was thrilled to stumble upon the KB8 adapter on Aliexpress a few weeks ago and received it a couple of days ago.
no evidence to who actual manufacturer is. Says it has the QCC3040 but its specs do not support aptX Adaptive and HD. It would have to be the QCC3044 for that. It also claims to support aptX LL and that’s where the issues began for me.
It connects to my FiiO UTWS5 and SoundPEATS H1 apparently at aptX Adaptive and that’s fine.
When it connects to my Maedhawk Receiver, it defaults to aptX LL. I think the adapter firmware has aptX LL above HD in the preference order. This is disappointing. Neither product appears to offer flexibility here.
Enter the downloadable tools noted in the KB8 manual. They are a bit tough to get without a Baidu membership. I got them eventually where my attention was drawn to an apparent ability to configure the codecs. It has however now dawned on me that the codec configurability may only apply to another model, called the KB8P. I can’t get the tool to edit the codecs with the KB8. How do I get my hands on the KB8P? It’s not obvious if this is available on Aliexpress.
Furthermore, there is also a tool referring to 24-bit/96khz. This led me to discover the KB8 is only capable of 16-bit/48khz. Not the end of the world, considering it is still Bluetooth but I’d still rather have the 24-bit/96khz unlocked. It’s unclear if this tool, again, only works with the even more elusive KB8P.
Anyway, I champion the person(s) responsible developing these transmitters this far. We non-Android users desperately need better Bluetooth codec options while we wait for the next evolution of lossless/Hi-Res wireless audio.
Does anyone know more about this adapter and does anyone have a link to get the KB8P if that’s what I need to turn off aptX and aptX LL and upgrade to 24-bit audio.
Thanks in advance.
