Right now Amazon has the 1st gen AirPods Max with AppleCare+ for two years for a total of $278 before tax. I returned mine two (?) years ago because while they were nice, $450 was a lot of money for something that I didn't really need. For under $300 though the sound quality and easy-of-use are worth it.

Oh sorry guys, looks like they quickly changed their minds.. back to $400. I managed to snag a pair though! 🥳
