Noise reduction works, it is audible even with one working ear. As far as I can tell, a non-working ear is not such a rare problem with this model. Addition: I received the second fish soup, everything is already working here. I picked up the ear pads, fits perfectly to the ear, corrected not a lot of frequency with the equalizer, now there are enough lows, the bass is quite elastic, I had to cut the top, but this is already for my taste. In general, an excellent model, if not for leapfrog in the working-non-working ear
