I purchased it yesterday, and today I tested it while riding an electric scooter.
I rode for three hours without removing the headphones because they were pleasant to wear and did not cause any ear fatigue. absolutely no noise cancellation. I activate the noise reduction while wearing headphones and there is a headwind blowing, just like with any other pair of headphones. My wife is speaking to me while wearing headphones as we are seated next to one other. When I activate the noise cancellation, I can still hear it, but the voice is now squeaky and unpleasant. In other words, this noise reduction just lowers low frequencies. Bass is diminished, and detail is lost, which affects music as well. AirPods Pro, which my wife has, offer much worse noise cancellation and bass. Technically speaking, noise cancellation on these headphones is simply not possible. To achieve this, empty the headphones of all microphones and sensors, leaving only the audio speakers, and the noise reduction will develop naturally. These are just fanciful stories for fools. I require sound, thus I'm not at all interested in noise reduction. The bass is strong, the detail is adequate, and the sound quality is good. However, the usual position of the software equalizer is the only one where everything sounds great. The rest of the equalizer positions are high whistles in your ears, and when you add bass, the bass rattles and makes a faint, muffled sound like it's in a barrel.
I tried it at a pairing distance of five meters, and communication started to break down. Additionally, I'm sitting on a bench, and if I turn my head, the connection occasionally breaks. A denim jacket's bottom side pocket contains the phone, which is 20 to 30 cm from the ears. Everything is fine as I hold the phone in my palms. There are five wireless headphones I own, so there is a basis for comparison.
