Apple has absolutely not gotten rave reviews on airpod pro sound quality. In fact that's that biggest complaint, they sound the same as normal airpods. I own airpod pros. They're great for what they are, noise cancelling true wireless that interact very well with apple products. But the sound quality leaves quite a bit to be desired.
On top of that, going off of what that review mentions, the AirPods Max look to solve exactly that problem and compete with exactly that range of product.
