High end headphones for mere mortals frequent travelers

Noise Reduction
###################
Works very well, primarily for uniform, low-frequency noise such as aircraft turbines but not only - when working now prevails finally pleasant rest. There is also no music with active noise canceling headphones on the very, very quiet to hear a noise.

Sound
#####
For the truly audiophiles this is certainly not a solution for the home, alone which distorts "pure" sound because of the whole electronics. Personally, I find the sound very pleasant and here the comparison to a few other models that I've heard:

- B & O H6: is the relatively close from the sound, however, less bland and a little more bass and a seemingly wider stage
- 550 AKG: not quite as audiophil differentiating but much lighter and more comfortable to wear less bass
- AKG 845: significantly less bass and balanced at 25 QC
- Creative Live !: Pretty similar sound, stage acts wider

Overall, the sound is very pleasant to listen to for hours - you will not want to settle the headphones, great :)

Comfort
###########
The over-ear headphones fit very comfortably over your ears. The headband is padded pleasant. The weight is relatively low and you can very easily carry it over longer periods.

Design
######
The relatively understated gray design looks more modern than its predecessor and is not pretentious. Depending on the light the patch BOSE logo is more or less reflective - I like that the processing is very high..

Compared to the former QC15

The new model now also further if the battery is empty. The sound quality is then not quite as good but much better than when he would no longer go.
