Exceptional Noise Cancellation
The AirPods Pro deliver excellent noise cancellation, but
you might notice that the ANC seems weak initially.
Simply wait a few seconds. The earphones first need to
measure the surrounding noise and create a custom ANC
profile appropriate for your current environment. And
then, when it kicks in, it's exceptional. Another positive
note—the ANC doesn't seem to introduce any noticeable
hiss in quiet settings, which cheap earphones often use
as a crutch.
In my tests, the AirPods Pro dramatically lowered
powerful low-frequency rumble (like you hear on an
airplane) after an initial adjustment period. In some of our
deep rumble tests, the AirPods even matched the
performance of the $299 Bose QuietComfort Earbuds,
which is impressive.
What's even more impressive is that, in some tests, the
AirPods Pro fare better than the QuietComfort Earbuds.
The problem, if you can call it one, is consistency, and
something I experienced with the AirPods Max as well.
The latter are also capable of shockingly effective noise
cancellation, but sometimes a slight head turn can
reduce their efficacy. The AirPods Pro are more likely to
remain effective after the initial adjustment, but
sometimes the resulting profile didn't impress me. But, to
their credit, a slight change to the in-ear fit can induce a
far more competent noise cancellation profile. So don't be
afraid to play around with how the earpieces sit in your
ear if the ANC isn't initially impressive.
