When buying headphones for $350, I expected premium quality and sound disclosure, new impressions, but the sound is no different from headphones under $100. The sound is rather mediocre, for amateur listening to music. The lower frequencies have a fairly wide range, but at the same time you will not hear powerful, low bass. At medium and high frequencies, I hear some roughness, and sometimes wheezing, they are not critical, but I expected more serious sound disclosure in this price segment. The latency makes it simply impossible to use wireless headphones for anything other than listening to music. From pressing a button to a response in the headphones, almost a second passes, this makes it difficult to even communicate comfortably in voice chats, there is nothing to say about games at all. Noise canceling dampens obvious noises, which can be called noises, such as the noise of a microwave, kettle, or drilling, but the voice or keyboard clatter is not sufficiently dampened. Noise reduction also adds third-party sounds. Headphones are positioned as a closed type. But they let all sounds through, so that everyone around will listen to what you are listening to, to some extent these are portable speakers. It is interesting that the manufacturer put a case, but saved on the cords, because if your computer or sound card is not on the table next to you, a meter cord is unlikely to be enough for a wired connection. If the headphones cost a hundred bucks, then I would probably put up with all these shortcomings, but for this price segment, I consider these shortcomings unacceptable. I wish bloggers who speak so enthusiastically about these headphones to buy them for their money and try to use them for more than a couple of hours.
