I bought these headphones specifically and only for air travel (not here). I have no comparison to the Bose QC 15 or other high-priced headphones, but they do their job very well. The sound is certainly good but crucial for me was the Noicecancellingfunktion. Here I can only report positive. If one removes the headphones on the plane, you realize how incredibly loud it actually is. Noice-canceling headphones on and on and the air is good to bear. Movies come over very well, much quieter than my old AKG K 450. One does not fully turn up the volume !!! What's getting used to is the huge case compared to the AKGs !!! Is really loose twice the volume !!!! My wife now uses the AKGs and eventually to exchange them against QC 20. Let's see and will report!
