At first, the sound "out of the box" did not impress - clamped bass, muffled highs and all that. Still, the notorious warm-up matters. After about 15 hours of warming up, everything fell into place, the sound became magical, "honest". I think it will get even better. Of course, he (the sound) is "signature Sonivsky" - a slightly failed middle, pressed high frequencies (but still very detailed) and an emphasis on soft bass. And at the same time very enjoyable. There is more than enough bass, its amount is regulated by a separate slider in the equalizer. There is a little lack of sub-bass and transparency on the treble, but I listen from an iPhone, I tried using LDAC from an android - all comments on the sound are reduced to "no", after all, the codec native to Sony. I don't see any distortion at high volume. The comfort of wearing without any complaints, except that the pillow on the bow is a little pressing (it could be softer), but this is most likely subjective. But on the ears themselves, they are almost not felt, despite the fact that they are large, everything is quite comfortable. There are no complaints about noise reduction. Better only in AirPods. There is almost silence in the subway (of course, no headphones will extinguish 100% of the noise). And the sound is not distorted when the noise reduction is turned on / off, which many manufacturers sin with. What I didn't like was this app. Somehow it is not comfortable. The same noise reduction is regulated in one tab, and its auto-control is in another, I didn’t even guess right away. And to change the equalizer, you need to poke several times. For such money I have the right to find fault. But there I played around, set it up and forgot it, it's not critical. I also did not observe any disconnections, in this part everything is fine. True, the range is 10 meters, the connection through the wall is already periodically degrading, but, again, this is a rare scenario. Who cares how to warm up - look for Tara Labs Cascade Noise Burn-in. You turn on the wire (with the headphones on) and go to sleep))) experts advise from 100 hours of warming up. In general, the headphones are probably worth the money. The key word is "probably". If you take for 30k, then this doubt will increase, and if 23-25k, then rather yes, they are worth it.
