What is pickup noise reduction? How about noise-canceling headphones AirPods Pro? Is it similar to a pickup noise-reducing earphone? If you fill it, you can't hear the outside world.

In fact, the working principle of noise-reducing headphones is involved here, so the noise-reducing headphones we often say mainly refer to "active noise reduction".

Active noise reduction is to collect the external environment sound through the microphone, transmit the sound signal to the earphone noise reduction processor, and the processor generates reverse sound waves to cancel the collected noise, thus realizing the active noise reduction process. This process is actually what you call "pickup and noise reduction".

So as for whether you will hear the outside world, AirPods Pro has a "transparent mode", that is, it can actively collect the outside world without noise reduction, so that you can achieve the experience without headphones.
