Man, I could have used your input a week or so ago 2left. Thanks so much! However, I have already bought a pair of JVC HA NC250. They are burned in and ready to go. I don;t wear IEM;s either. I wish I could, they are so effiecient now, but I am unable toi wear them comfortably. Also, I don't fly, I only need the cancellation for street use which is a little more forgiving than a Boeing engine. Glad to see a fellow headphone junkie on here...
