I have a special interest in ANC over ear headphones for work and travel and do buy nearly every serious contender as soon as it becomes available (I have or had the BOSE QC35, QC35 II, 700, QC45, the SONY WH-1000XM3, XM4, and the AirPods Max. I‘ve yet to buy the XM5s). The AirPods ANC is far beyond the competition especially if it’s cancelling noises other than continuous rumbling like noise spikes, human voices and such. All of them are good or great at blocking background noises (even the original QC35 is still capable enough there), but the AirPods Max are far superior in unpredictable environments. This isn’t some magic BOSE or SONY are incapable of, this is just economics: Apple charges more than double the competition‘s prices, has special access to chips and isn’t just a scammy luxury company without serious RnD, but also has the resources and knowledge to develop outstanding software. This isn’t a judgement on the other factors though: the Max are heavy, their sound is borderline “Beatsy” (no surprise there, since they are probably related), they have nearly no external media control, the bag they come in and the way they are stowed makes them really unwieldy - and first thing you need to do if you receive them is tape over the little “SIM ejector”-like holes under their cushions as the article describes. Their superior ANC comes with a lot of costs attached.
