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 Riko Mizuseki ᠌

Compared with BW PX, Sony 1000 XM2. Sonya didn’t like it, not in terms of sound, not in terms of execution (although the application is gorgeous) The tusks sound great, but the fit on the head is something. BO H9 fit much better. You practically don't notice them. Noise canceling cuts off only low and medium noises, leaving high ones. Only one mode. It's like BW and Sony's speech passthrough mode. But on the plane, train and subway enough. If they do not add a "transparency" mode in the near future, I will look at the H9i.
