The Denon had quite a long history in Hi Fi before recent years saw them going into personal audio.
Or it might have been 5-6 years back, demands for earphones/headphones is not as great as compared presently!
I'd a quick listen to that P372 headphone when one of my friends bought.
Quite nice and balanced overall.
But no way to be compared to other high end headphone makers!
At that price mark, is very good bang for the money!!
