Hello guys, i ordered that little usb-c nub that has the same chip as the fiio j11. I remember i saw some guide somehwere regarding what to do to make it work with the fiio software but i dont find it now again.
I already have the fiio unit and dont use it so this is just experimental but quite fun 
This is the link to their web app.

Try with that or their android app.
Not sure if you need to do anything more than just plug and play.
Edit: May need to flash the firmware like this:

and maybe this as well.

it worked! hardest part was to find a PC! but after convincing her she wont get fired from the software i needed to download it was smooth sailing. theoretically can now buy one for each IEM and mark them with some pen or stickers 
For reference, did you need both links?
i did not try without the drivers so im not sure, i just got it straight away to make sure!
@Rikudou_Goku do I recall correctly that you’ve been working on another bud in the “Grand Alter _ 3” series? Caster? Any updates on that? 
Grand Caster 3 is in the works.
Awesome 
Can you explain again (sorry I know you’ve clarified somewhere, link if you can), how will that tuning then land relative to GAS3 and B3?
I am still uncertain as it is still in R&D.
