Review on Beoplay H9 3rd Gen Wireless Bluetooth Over-Ear Headphones by Bang & Olufsen - Active Noise Cancellation, Transparency Mode, Voice Assistant Button and Mic, Matte Black (Amazon Exclusive Edition) by Arina Foliez ᠌

Before buying, I listened to almost all ears of this category (budget, wireless with ANC). I liked B&O most of all in terms of sound: honest and linear range, authenticity of voice and instruments. ANC is great for wind, walking and chewing. But the first thing that disappointed me is that the darling is narrow and harsh for such a weight of headphones, you have to constantly change its position on the head. The ANC mode adds a lot of noise at high frequencies, as well as the sounds of switching headphone modes and the operation of the UPS. You can’t listen to them at a quiet volume, just like at a loud one - where the sound turns into mush. the most optimal is the middle, where the whole range is revealed, and the instruments still differ. For me, the volume of these headphones is enough. When you change the volume, as well as turning on the ANC, the frequency response changes, which I consider unacceptable for such a price. The application requires the Internet, without it it does not even start, and it starts for about 30 seconds. Of the possibilities, only change the timbre. Turning ANC off is not retained after the headphones are turned off. In passive and wired modes, they play almost the same (tested on a Marantz receiver), which indicates a good wireless transmission. Passive mode requires equalizer settings. Another minus, as I think, is the lack of an ultra-low pass filter. In the case of bad old recordings, where there are such sounds, the headphones put a lot of pressure on the ears with an inaudible range.
