Impressive as they look (and from their description) sound. They seem way over priced.
I have a pair of Bowers & Wilkins PX7 and these cost £300. For me I can't see the AirPods Max offering sound quality or feature value that is worth an extra £250.
I also don't like the look of that mesh material on the earcups, it just doesn't look durable. I prefer the leather/artificial leather that are on most other earphones.
Too be fair, it would be an impressive product if it were in the £300 price range.
Or and that so called carry case, it looks pathetic.
