Airpods Max are good compared to their direct competition, Sony XM5, Bose, but they're not amazing by any stretch. I think something like a $100 AKG K361 sounds better tuned, and the airpods max are all about the features and name.

The drivers themselves are just sort of crammed into the cup with minimal room, and DSP does all the work to tune the drivers to sound decent. But still they are missing a lot of upper mids.

I wouldn't pay full price for them
