I've been using it for about 1.5 years. There is noise reduction, if you switch the noise reduction toggle switch in a noisy place without sound - you can hear the difference, how the noise becomes less, but this does not help in any way in noisy places, in the subway, on the street . Got pros: Not a music lover, but the sound is good. I liked that you can simultaneously connect the headphones to both the computer and the phone. Convenient control buttons on the case. It connects quickly and without problems via bluetooth, and also reconnects itself without problems when you turn on the headphones. Has some cons: I use it as a headset for conferences on my computer. I don’t know, maybe I have a factory defect, but the microphone transmits the voice very badly. They constantly tell me that they can't hear me well, I work in a quiet office. When switching to a regular wired headset, they say that they can hear me very well and clearly. In general, I bought it for the convenience of working when connected to a computer and to a phone at the same time as a headset with good sound quality - because of the microphone I am disappointed, so much money wasted . Fragile body - the arc on the headband cracked, apparently with frequent removal of putting on .
