The Arya Organic is definitely one of my favorites. The Arya/HE1000 design in general are THE most comfortable headphone design as well. Very light, good support on top, very open (stays cool), and surround the ears without touching. Bass is very nice, deep, and impactful. Treble is also good, bright but smooth. Compared to the HE1000se the organic are more v shaped sounding, but not by a lot. Still sound very similar. HE1000SE is a bit smoother and has more natural mid range.
