^^ Nice find, just tested and it works fine even LED colour in App changes but the box for HQ remains checked so assume it will go back to that if disconnected then reconnected just a pity you cannot force or cycle all the codecs same as BT-W3 and older ones.
I checked the HQ/LL state when replugging the BT-W5 between my smartphones and PC's. Always the latest active HQ/LL state will become active when coupled to a new device, so the state is stored on the BT-W5 itself.
The state is only changed by the PC when selecting the device in the Creative app (or selecting an another config menu in the app when BT-W5 is the selected device) and when the HQ/LL state in the app is different than the one stored in the BT-W5. So the HQ/LL state is not changed when plugging the BT-W5 to another device.
Of course it would be better if we were just able to scroll all the available codecs.
Not that would change much for me when using the Bose QC Ultra Earbuds. The only decent codecs available here are the AptX Adaptive HQ and AptX Adaptive LL.
Standard SBC and AAC are just meh and not enjoyable at all, at least not for me as I am used to listen to high quality sources (e.g.Tidal Hifi Plus) with decent wired headphones.
Although forcing the SBC with the Alternative A2DP Bluetooth driver to use a bitpool of 102 (what the Bose QC Ultra can handle), yielding in around 650 kbit/s bandwidth, was also giving a quite acceptable result. I was rather surprised by that and I am also just wondering why these tweaks did not just became mainstream, and everyone still continues to use standard settings for SBC dating from 20 years ago ... .
So tweaking can also help, but as stated earlier in this thread the whole bluetooth audio situation is just a mess, and also a little disgrace for vendors and OS makers that just not really seem to care about decent mainstram wireless music quality.
But luckily I am at least quite satisfied with my BT-W5/Bose QC Ultra Earbuds combination when I need to go wireless.
