I was looking for a headset with noise reduction and have the most well-known all tried. The noise reduction works in a slightly better than the other, they do all sound very modest (especially the Bose QC 25) - except for the Philips Fidelio. I mainly listen to classical music, I value a very natural and spacious sound and that can of Philips. If you turn off the NC, there is no big difference in the sound. He is also very pleasant (OnEar, so no shell), great soft material, fabric coated cable - very fine workmanship.
Who expects the NC ALL rausfiltert, will be disappointed, but noises such as buzzing, train or plane noises can be reliably filtered (also as with all other models) - it has an immediate sense of tranquility, if you turn on the NC.
For me, by far the best headset with Noise-Control.
