Yes, the 'high-end' counterfeit AirPods are so good, they show up in iOS with identical set up flows; battery indicators; feature support (at least claimed to iOS), etc. I'm not sure about AppleCare though.
The packaging is basically identical, unless you carefully scrutinize font DPI or alignment.
Have a look at YouTube videos; for a good AirPods counterfeit it's genuinely hard to tell things apart.
