I had a chance to listen to them compared to my Grado SR325e headphones. Put plainly, the Airpods Max suck musically/sonically compared to a $295 set of dedicated headphones. The Grados are dramatically clearer, punchier, easier to listen, more dynamic, and have more extension in both the bass and treble, without the annoying electronic haze that the Airpods Max coat music with.
So on sound quality grounds, save your money.
However - if you really want what the Airpods Max do, sound quality is probably not your first priority, so if you have to have them for whatever reason, go for them. On second thought, perhaps get a different pair that costs half of what they do, and donate the rest to a relief organization - there are a LOT of people who need the help WAY more than anyone needs AP Max, let alone Apple needing more money.
