Summary: I received the Bose QC 15 in the mail today. My previous ordered was canceled by the retailer for some reason. I went back to re-order and the price was marked down to $229 shipped. Probably a Black Friday deal or something.
Summary: Just a quick note about these. My point of comparison for Audio Quality is Senn HD650 / LCD3 / Grado 325is / ATH-M50.
Comfort - Amazing. Gets slightly warm after really long listening sessions, but they mostly rise to that level where you forget you have them on. The cups are like pillows.
Pros: Great noise cancelling with *good* sound, works extremely well out of an ipod
Conclusion: The best noise-canceling headphones we’ve used thus far are Sony’s more expensive MDR-NC500D ($399) model. Overall, these units have a wider dynamic range, but the QuietComfort 15 unit does a better job blocking out extraneous noise, a critical requirement for keeping your sanity while flying.
Pros: Superior noise-canceling system; very comfortable; good frequency response
Cons: High price may trouble some; not the ultimate solution for audiophiles
