Neutrality is the holy grail of high-end audio listening. Airpods Max are not aimed at that holy grail, but they are likely to be better than the competition in many ways and bring some unique things also.
Sony XM4 scored 8.1 for neutrality on rtings.com, I wonder what APM will score. I think they will score better.
The problem on sites like this is that most people don’t even know what good sound is. Why do you think awful headphones like Beats and Sony XM4 sell so many? So many people want fake bass and a cheap price.
Let’s take EQs. Most people that use these make music sound worse because they don’t know what good sound is. EQs should only be used to correct the failings of the environment and equipment being used, not for listening “preference”. Added fake bass is like the inflated saturation of TVs on display in retail stores (pleasing to many, abhorrent to those who know better).
The fact that Apple has not provided an EQ app is a sign of quality, as is the use of adaptive EQ.
So real reviews are what I await.
