In general, there is nothing to complain about, it gives out everything that is stated, 100%. But to be honest, I was expecting something more. 6 years ago, Sony MDR-EX310LP wired earbuds for 2k (12 times cheaper) sounded just as good, perhaps even richer in places. Well, yes, now there is fashionable noise reduction, but for me personally it has never been necessary, I have never heard external noise with headphones on. In short, now I'm inclined to think that it would be possible to buy a simpler model (for example, the Sony WH-XB900N is 7k cheaper) and not really lose anything.
