A:AnswerNot sure on impedance but rtings.com did a pretty good review of them going over sound signature with graphs/charts if you are into that sorta thing.

As far as the serious specifications goes... that is how Apple has decided to release/market these headphones. I don't think these are anywhere near targeted toward an audiophile who is looking for top-tier listening headphones. These are for Apple ecosystem users who have the money to spend on a premium product that is a step up from AirPods Pro. Now when I say premium I don't mean audio quality vs wired headphones but in their class (ANC, wireless, etc) they are really good. If you compare then against other wireless ANC headphones they will win most fights from sound quality, ANC, ease of use (if you're into the whole Apple ecosystem), swapping between devices seamlessly, etc. Their build quality (aside from the case, yikes) is leagues ahead of another competing ANC wireless headphones as aluminum and stainless steel aren't cheap materials and the machining is top notch.
It's one of those, you're buying it for the whole package and the name kinda gigs. If you're questioning yourself as to "why would I buy it when I can get better stuff" then you probably aren't the target audience for it. I know that sounds weird to say but it's the same reason someone will spend extra on a high-end item like nice shoes, a purse, a watch, etc. They're buying it for the whole package and are willing to spend the extra money. Casio and Rolex both tell the time but the Casio will set you back $20, the Rolex $5,400.
I'm not saying its right or wrong that's just how it is - Apple is a luxury brand and that's how they have placed themselves in the market.
A:AnswerI can only speculate on the cost of the Airpods Max. Part of me thinks it is typical Apple product pricing. But then I compared the Airpods Max to the following headphones: Bose 700, Sony XM4, Sennheiser Momentum 3's. I initially returned the Airpods Max because they cost the most. However I soon realized I missed the sound quality and I purchased Airpods Max again. I am happy. I have since returned the aforementioned headphones. I believe the speaker drivers and internal components and sound quality justify the price for me.
A:AnswerYes. They connect to any Bluetooth enabled device. Though certain features (like spatial audio/head tracking) only work with apple devices. But I use these with my iPhone/iPad/MacBook as well as my windows computer at work.
A:AnswerThe Airpods Max have a microphone, and it is quite good. A bit better than standard Apple headphones, or even the microphone on the Airpods Pro.
A:AnswerNo. Apple forces all third-party retailers to sell Apple Care protection plans only. Third-party stores cannot offer their own protection plans for any Apple products.
A:AnswerNo, it sounds like you need a Bluetooth transmitter.I bought this off Amazon and use it on my PS4. It also works on PC.

A:AnswerThis will depend on what you're streaming through your connected device. Airpods Max can listen to very high quality audio that has been encoded in Apple's proprietary codec, as well as higher quality "lossless" audio files which are generally larger and will use more of your data, but this isn't related in any way to the actual Airpods Max. They will receive the maximum allowable bandwidth of bluetooth, which Apple has said they wish was higher. Forgive me if I misunderstood your question, hope this is useful.
