My experience with headphones: A closed-back headphones attenuates ambient noise very well off, and when the same music is still recorded, you can hide the ambient noise quite well. Without music, so for example when making calls with the headset, the filtering already works less. Quite bad it when low sounds coming from the outside, such as the deep voice of the colleague in the same room, the roar of the train, etc. Since this is transmitted through the bone, it will be as good as not damped (they are by the earcups only slightly muffled). Since the high frequencies with headphones are no longer audible, the deep, still audible sounds are felt even louder, at least more disruptive. The "Noise Reduction" I see therefore complement the damping function of the ears: A tightly sealed ear attenuates the high notes, electronic Noise Reduction combats the low sounds quite effectively. Just as a closed headphone hides all sounds, the (not even for low tones) creates the Noise Reduction. Nevertheless, the Noise Reduction works quite well in my eyes (or ears). On the train the Rattergeräuche be reduced by 80% felt. The voice of a male speaker on television is no longer with headphones without switched NR understand yet, after switching on the NR. (They will perhaps was, but is no longer distracted that you unconsciously trying to understand words.) Other humming noises, such as washing machine, heating, snoring, ... are also successfully suppressed. Although they are not completely gone, but no longer perceived as an isolated sound.
I was therefore convinced of the headphones in the following disciplines: + As travel headphones on the train or plane for damping booming noises + To hide deep male voices in shared offices if they interfere with the concentrated work
What I noticed is negative: - At my last trip I after the outward forget to switch off the NR. During the return journey, the battery was of course empty, and I had to abstain on the night train to NR. An automatic shut-off if there is no music signal is present or the cable is disconnected, would prevent that. (As a workaround, I have now obtained a replacement battery into the case.) - The headset is bulkier than an in-ear headphones and therefore restricts the Anlehnpositionen for the head. When dozing in the train that has led me to tension in the neck area. Also in the luggage of headphones is more difficult to store as an in-ear headphones. I shall therefore consider whether I will prefer not to rely on my next trip to the default existing noise reduction: Finally, the brain appears even successfully monotone noise from.
