It's an 'air purifier' that is supposed to clean the air you are breathing.Ha, that's insane! What's the deal with the mouth guard thing, is that somehow a mic in there, but I don't understand why you'd want a design like that??
In certain cities it may actually not be such a bad idea. You would have to replace filters regularly I reckon.
There is a little fan inside the cups (and why they are so thick).
The NC is kind of important to reduce the sound of the fans.
