I don't like attachments. I am a person who does not like the "environment of devices", tk. you are constantly tied to something and like paying money, buy only our devices, build an "ecosystem" and everything will be ok, and additional functions are also by subscription . Here they did it with support for adaptive noise reduction for external sounds (krivova works - then, then it's better to turn it on 100%) and with "super 3d sound", which simply uses a different codec that will only work with the same ecosystem devices (such as poppies, with their iTunes, Sony, etc.). Some functions are located in the application, while inconvenient.
Noise reduction, although it works well, is safe (at least they write that way), gives good psychological peace (I lived near the airport, it was my dream), but my head aches, I feel pressure, as if I dived a couple of meters under the water, it is not felt right away , but that's the point. I sat without noise reduction for half a day, it was normal, I quickly got used to the dimensions, the convenience of the bends of the ears helps to open one when talking with someone in parallel (although there is such a function, but typing the 3rd with both hands is inconvenient to close the ear). Oh yes, with noise canceling you can’t even hear the call, this is rather a plus, but you can’t be on duty in them.
Regarding the connection of two devices: it is logical that you can only speak through one of them, however, for some reason, inside one device (game + discord), it does not output the sound of the game and the disc at the same time (although in the settings it was indicated "do not press the sound in the game when talking and in Windows, this is also worth it, "other headphones do not do this), but it can also be a jamb of Windows or my settings.
I'm very afraid for the fasteners, because, from experience, I know that this is the most common thing that breaks after a year or two .
