Noise reduction only cuts off low frequencies, but high frequencies are muffled by music at a volume level of 40%. Someone will not be satisfied, but everything is ok with the noise reduction. There is an adaptive mode that scans the surrounding sound. However, why are these levels needed - xs, I almost always have it at the maximum, so that no random harsh sound is distracting. Maybe to save battery, but it''s always enough. Occasionally it slows down due to a change in the volume of the environment, switching the level back and forth once, you notice it. In "transparent" mode, with the cup closed, the microphone records sounds from outside and plays (ideally, without delay) into your headphones, noise reduction is turned off. But the microphone does not have an infinite range, in the distance speech turns into a mess. This technology is not magic and you should not expect it from it. In the vast majority of cases (80-90%?), you will have enough range. /total/ Every technology in a vacuum is great, but there are clear limitations in use. Bluetooth cuts the channel, noise reduction does not work perfectly for someone, half of the functions from the mobile application do not work as they should (3D sound is a toy at a time), the case creaks. The sound quality will cover the requirements of the majority of the audience, you are unlikely to be disappointed. /Grade/ For 7-10 thousand, these are ideal ears for 5 stars, for 15 - I have a higher requirement. If they work over the next two years, and the ear pads do not become unusable (in 2 years you will not find them on sale), then 4 stars. If they donβt live even two years, the score is 2 out of 5. The previous headphones lived three times cheaper in worse conditions for two or three years. /Whether to buy/ What do you expect from this product. If the described restrictions are not essential for you, you will be happy with this purchase. If hooked, the sediment on the soul will remain throughout the entire use.
