RTINGS robi pomiary i po zmianie firmware też sprawdzają, czy ANC się zmienia, gdy userzy narzekają. W skrócie – jest gorsze niż było. Ostatnio sprawdzali pod koniec zeszłego roku:
Update 11/01/2021: Apple has released multiple firmware updates since we last updated this review, and we decided to retest everything. While most results match our original measurements, ‘Noise Isolation’ has changed. After updating to firmware update 4A400, the headphones’ noise isolation performance has slightly declined across the range, and the overall attenuation dropped from ‘-23.01 dB’ (measured using update 2C54) to ‘-21.31 dB’. We did a fit test between each of our passes to ensure the best possible seal. We also compared these results with a subjective evaluation of one of our coworker’s own Apple AirPods Pro, and our unit performed similarly to this pair. Our results now reflect firmware update 4A400, and the scoring of this box has changed.
The noise isolation of these headphones is great. They perform somewhat similarly to the Bose QuietComfort Earbuds Truly Wireless in the bass range and do a great job isolating the low rumble of bus or plane engines, making them good for commuting. Their mid-range performance is also solid, making them excellent for blocking out ambient chatter. Their weakest isolation performance is in the treble range, though this is the least important for most situations, and they still do a good job. That said, if you’re looking for an even better noise isolating performance, check out the Apple AirPods Max Wireless.
Note: We’ve tested ‘Noise Isolation’ with a couple of other firmware updates. We didn’t get noticeable differences with firmware update 2B588, released in November 2019. Apple may have tweaked the ANC in this update, but not enough to noticeably impact the overall performance. There have also been user reports that the ANC became worse after firmware update 2C54, released in December 2019. After updating this firmware, our results showed a fairly significant drop in isolation performance, primarily in the bass range. This means that with ANC turned on, they won’t do nearly as good a job blocking out the low engine rumbles of planes or buses as they did before this update. Our latest retest uses firmware update 4A400, released in October 2021, which shows that their overall noise isolation performance has been further weakened.
AirPods MAX za to pogorszono ANC w ostatnim firmware o ok. 3 dB (albo nawet 4, już nie pamiętam). Co do AirPods Pro 2, to IMO ANC znakomite, na pewno najlepsze z jakim miałem do czynienia, ale ciągle jest całkiem spore pole do poprawy, żeby mieć zupełną ciszę w każdych warunkach.
