Cannot change noise cancellation during phone calls (QC35ii)
I recently purchased a new pair of QC35ii headphones. They mostly work well, but I have noticed that the action button does not seem to work during phone calls (I have an iPhone). While talking on the phone, I cannot change the noise cancellation setting from high to low to none by using the button. Instead, I have to manually switch the setting in the app. Is this normal? If so, why is this part of the design? Or are these headphones defective? Thank you!
(By the way, I have already tried resetting these headphones using the Bose recommended method.)
