I bought these (not through Amazon - at B&H in NY) before a 10 hour flight to Istanbul, had no chance to try before the flight. Previously I owned the Audio-Technica ATH ANC3 and the Sony MDRNC33 both of which are priced around $50. I find the Denon lacking in both the sound quality (very low bass performance, making the music very flat) and especially noise reduction as compared to the other two. I use the Audio-Technica ATH ANC3, my son uses the Sony MDRNC33, and the Denon was a gift for my wife. I had all three earphones on the flight and could compare them. Sony and Audio-Technica were almost equal in sound quality and noise reduction, Denon was much lower in both aspects, in my opinion. Knowing what I know now, I would not buy it for any price, as this performance is way below my expectations, if it were selling for $10, it would not tempt me. $200 is in my opinion completely outrageous. I pity myself for having bought this at $200 and painting myself in a corner where I cannot return it. This is to help you avoid the same mistake. At least listen to it before you buy, sound performance would be enough to dissuade you.
