1. The sound for this money (bought for 26,000) did not impress either with the hyped LDAC codec (turned it on both on headphones and in a smartphone), or by wire. By no means a bad sound, but there is no “wow effect” either.
2. Noise reduction, which was praised by all the reviewers, in fact, of course, there is, but I expected more. If someone is talking nearby (not yelling, but just talking) - you can hear it. Muffled, of course, but audible, the words are easily distinguishable. When I type on the keyboard, I can hear it. The noise of transport cuts off significantly, but does not remove it at all (I'm talking about the bus, I haven't tested it on the subway or on the plane). In the application settings, the maximum level of noise reduction was set, all the optimizations that were offered were also made. In general, if this is, as they say in the reviews, the best noise reduction at the moment, then this technology still has room to grow.
3. The abundance of intellectual functions rather interferes. They work very poorly, and the elementary things that all manufacturers have work even worse. For example, a banal playback pause when you take off your headphones works a couple of times out of ten. I used to pause myself when removing the headphones. Of the interesting functions: "put your hand on the right cup - and the music will die down, and you will hear everything around" - it works crookedly, it does not always work the first time. Again, it's easier to pause and remove the headphones. Due to the "optimization of atmospheric pressure" headphones often crackle while riding in vehicles. I don’t know what kind of drops are on the bus. Determination of the listening mode (rest, movement, transport) - works very poorly. When riding a bus, the headphones either think that I'm walking, then that I'm going, then that I'm just sitting at home. As a result, turned off this function - its work is annoying.
4. They do not look like 26,000: they are light, the materials are solid, but without frills.
5. The battery does not hold very well. Enough for a week of not very active use.
6. Very short Type-C charging cable.
