Very strange and bad noise cancellation. The noise does not completely suppress, moreover, if there is silence around, then some kind of white noise is heard. But I wouldn’t say that you can’t hear the difference, it still crushes large street noise. But there is a big problem with it - if you listen loudly (the last 2 divisions) of audio with noise reduction turned on, the audio starts to fart, sound like bass boosted, and so on. I noticed this back in the store, I decided to score it, since in principle it makes no sense to constantly use noise reduction (the headphones sit well and external noise is not particularly audible when loud music is on, and when listening to calm music, there are obviously no problems with bass-busted), but the fact itself unpleasant.
Pass-through does not work well and does not turn on from the headphones (only manually through the application). Bad - it means metal is added to all external sound, as if you hear everything around, synthesized by Griffin Lim. And okay, again, it would be possible to score, as well as with noise reduction and not use it, but this function is turned on automatically during any calls (he managed not only to recognize it in the messenger, he turned it on when I was in the browser from a macbook via google meet phoned) and did not turn it off at all. The head after 15 minutes of this function begins to ache.
Headphones are not friendly with Apple technology. Here they wrote above about the fact that on the iPhone the interlocutors hear themselves, the same thing happened on the MacBook. The truth began to bug not immediately, but some time after the start of the call. I called up on android in different applications and places, I never caught this, obviously a software problem.
The in-ear seat sensor does not work at all. It's impossible to listen to him at all, when walking, he stupidly turns the music on and off in a second.
Today I caught an uprising of headphones against me - they started switching music, turning on an assistant, not responding to pressing, etc., until I put it in and pulled it out of the case, nothing was fixed. It was strange, but I caught it only once, I hope this will not appear often.
