I think they are in the same category, but different quality levels.Your funnny (not) asking if a under 400 euro unit is in the samme category as a A8 G2 thats cost 2000 euros or more, yes if your ask if both are the same type of units but sound, the eversolo should be the superiour unit, if it's the last, why would you compare a under 400 euro unit to one that cost atleast 2000 euros
The only way they would be in different categories is if we consider price and build quality as a category definitions. As boxes they do the same thing.
