So far, white noise has been acting as a fly in the ointment with noise reduction turned on. I went to the store and changed it to new headphones, absolutely the same situation - the same level and also out of the box. I watched a video on YouTube with examples of xm4 noises that are amplified, vibrate, etc. , it's not them. I'm trying to understand - is it a marriage or is it conceived, will it be treated with firmware as written earlier, is there any point in testing another pair. On 4p da they suggested that this noise is normal, so this is a feature of these headphones. You will choose, pay attention.
