You’re such a funny person…sarcasm and all! Printing statements out of context benefits no one! No I have no more information to share official or otherwise…at this time! When I do…l’ll post them!
Furthermore PD as a standard is not always implemented correctly or it tweaked by the manufacturer. Anker uses a proprietary implementation they call it which supposedly approximates PD. There is also QC used by Belkin.
I suggest you do more research before making criticisms!
Saying something like ‘Please be advised….’ and underlining it sounds as official as it gets and for the other comment quoted but linked, I specifically said they read as being official, I didn’t say that they were or that you claimed they were official - but the wording appear specifically to look official.
Regarding doing more research, I’d be interested to see where your research has shown that Anker etc. use a proprietary implementation despite claiming they are literally PD. Similarly, QC is a separate, but similar technology to PD so again, links showing QC is being passed off as PD would be welcome too.
For me, if they say they’re PD they should be. Although, complying with the mandated voltages and currents should be sufficient and has been on any USB device I’ve ever owned - long before PD was a thing…..
I bet it goes something like this
“Please be advised Ace is Not Defective, get your ears checked”
It’s pretty wild that they recommend a usb charger that delivers 15w should work but here we are told Anker and Belkin are a hard no 
“There is a compatibility issue with certain PD certified chargers.”
So it’s the chargers not the headphones

Just a little background for the curious: the USB-IF organization sets the standards for all aspects of USB—PD included—and sets testing criteria.
While one assumes the random-six-character companies (cough, Amazon sellers, cough) may play fast and loose with the specs and assuredly skip third-party testing, the name brands absolutely play by the book. I’ve run this gauntlet (working through a third-party testing outfit) and it is a formal process.

Hi @AjTrek1 et al,
I’ve removed some replies from this thread, please stay courteous and on topic for further replies or this thread will have to be locked.
To add to the original post, these are the chargers that have been tested which fail to charge the Sonos Ace:
- Anker PowerPort PDNano (A2634) with PD
- Tenker TA06A3
- Kovol Sprint 65W PD GaN Wall Charger
Not all chargers are affected and there may be other chargers that are not on this list which have this issue, but our team are aware and investigating this issue.
Thanks for listing some non-compatible chargers.
It appears that it's not true to state that the likes of Anker and Belkin should be considered as Non-Compatible PD Charger Brands and having them listed as such could cause confusion.
To say that “Anker uses a proprietary implementation they call it which supposedly approximates PD. There is also QC used by Belkin.” is also currently baseless and could cause confusion.

You’re welcome.
Please read @Jamie A post. I bought and tested several Anker models as well as several Belkin models and the EZQuest model. They did not charge the Ace.
The one’s listed as compatible I bought and tested as well.
FYI, that’s what meant by “hit and miss”. Bought and tested.
Also, check cables, some cables have ‘E-Marker’ chips in, that may or may not affect compatibility.
My ‘thank you’ was to Jamie as he listed some specific chargers with compatibility issues
