Have now tried the headphones on the plane, on the train and in general in the city. The Digital Noise Cancelling is a dream, especially on the plane !! The noise generated is almost completely suppressed and it remains only a faint noise. If you have music or run a movie reaches a very low level before you actually heard nothing from the plane. Another advantage, the noise reduction works even if no music, no movies or run so perfect for sleeping on long-haul flights (Attention must be adjusted in the settings, otherwise the noise canceling turned on for power saving off when the display goes out when the battery the Z3 but no problem).
This noise reduction only works if you are connected to Xperia devices. That one looks a film eg on the plane on the monitors of the flyer does not the noise reduction. But for the headphones do not require batteries / accumulators such as the models of Bose.
The InEars also sit very comfortably in the ear without the pain you get after a long time, you just have to plug the right size to use (3 different sizes included).
The sound is also really good! Powerful bass, no clinking, totally satisfied. If not quite serve up some devil Move InEars, but cost only half as much. And the noise canceling balances this out again.
I can definitely recommend it for owners of Xperia Z3!
