Sound good and have a rich sound,

But I am determined not an audio expert. The noise suppression function properly. Miracles can not be expected surely. The noise of my rowing machine can not suppress what little disappointed me the headphones unfortunately. But there is certainly no profile. Noise reduction profiles are available for train, plane and office. I've tried both the train and the plane and am satisfied on the whole. Of course, still sounds at a more urgent approach, which is not bad either.
When you stand in a large crowd with chattering people who earphone dazzle even with soft music very effectively from the noise. Anyway, you have to, thanks to noise suppression make the music never very loud and for so his ears.
Especially on the plane you realize how good the noise reduction works when you issue times. A white noise, however, remains.
