I'm a music lover.
I own a lot of external DACs and some of the highest quality analog headphones out there.
If you are listening to streamed music, there's nothing better than AirPodsMax. It sounds amazing.
As equal as the highest quality analog ones.
And its build quality is fantastic. The posts about condensation and other issues are a pretty frequent phenomenon that happens when you deliver such a complex product to ordinary people.
Condensation inside the cans isn't an AirPodsMax issue, but an issue common to all around the ear headphones with closed back. It's simple to understand that something that keeps the air in a closed shell in contact to human body (that produces heat) will lead to some level of condensation, isn't it?
Regular users doesn't know the need of maintenance in such headphones, because they never have access to it before. I love Apple for this effort to deliver regular people high tech and complex products.
