Impressions are cool, worthy ears, very happy with the purchase. Has some pros Excellent sound, many tracks sounded new, and some artists have become favorites. Each instrument has its own place, each one is heard separately. They sit comfortably on the head, the battery is long, the noise reduction is cool. Its cons: If you shake your head strongly, turn very sharply, or, for example, when you carried a heavy box along the road in your hands, you will experience sound distortion. It's hard to describe, but it's like the sound is twitching. The battery once sat down almost immediately at 20 percent, although it was once and after the first charge.
