You are wrong, and I am not imagining things - otherwise I would be alone complaining!
Canceling was sufficient at first with the initial firmware. Now I went and bought Sony WH-1000XMs and the blocking on them is really nice. Of course I am playing music at the same time, but now with APPs even through music I can hear people’s conversations. In mostly concerned about engine noise and losing the ”bubble” effect. It seems the frequency the canceling is effective at has changed. Our dryer it blocks quite well, but there are no dryers on the bus or subway..
I remember missing my subway stop once with APPs on as I could not hear the announcements. Definitely returning these unless a new firmware fixes this soon.
