That paid for itself ...

I'm not a technology specialist and was thinking long whether I need relatively expensive headphones. But as I spend quite a lot of time on planes and trains, seemed to me the idea a noise-canceling headphones to buy useful, besides, I do not like the big headphones.
To come to say - I did not expect that these little things can produce completely calm and they do not do it well. But the level is lowered to the ambient noise, in my eyes (ears) is already impressive. Quiet music passages make finally also fun without turning up the volume. On the plane, the quality is sufficient to to without music, can sleep well - the engines murmur softly only. On foot, the effect is so good that it must be really careful before you cross a street. Cars become electric vehicles. For me, the seat is good and the sound quality (with and without) amplifier well. Sure, the small box is used to, but somewhere you put the phone down, too, and because the matches then at that.
