The ability to turn the different active listening modes off completely has apparently been removed in this update. Transparency mode seems to be the default setting now. I am very unhappy with this change as I do not like the noise allowed in with transparency and adaptive mode, but I also do not want active noise cancelling at times, either. This is especially a problem when I'm listening with only one AirPod at a time. I hope they restore the ability to turn all these modes off. If not, I'll be switching to another brand.
