Hmmm.... Wanted to have my APPros replaced because of rattling / weak ANC / continuous fit test fails on both.
Cleaned them now (speaker and both external grills) with type cleaner (Läufer Typutz), which already solved speaker/mic issues on my iPhone X, and now they sound like new - even the fit test works on both APPs again.
Still have them under AC+ for over a year, but I think I won‘t need it just now.
Addition: Spatial Audio is impressive!
