If you take it, then only to use noise reduction. I am extremely disappointed. It's not about the price. The price is what you accept or not, in exactly the product itself. I'm not an audiophile at all, but this is a disgrace for 23 thousand. For 11000. after this nightmare, I bought Soundcore Q35 from Anker and am happy as an elephant. Yes, the noise reduction is a little weaker, but in general it cuts off the excess and, most importantly, without discomfort. Sound 16-40000 vs. Sony's 20-20220. The equalizer is great. Reacts to changes. The sound, the assembly material (iron bow) and the appearance of the Ankers are many times better. Don't be fooled by the brand and price. See reviews, read comments. Another good option for 5000 is Edifire 820. Also a cannon. But there the material of the assembly is not very good. But you need to take headphones from a company that deals specifically with sound, and not selling everything in a row. In short, there was a return, but a separate respect to the seller, who returned the money without question. Level of customer focus. There is no negative left.
