1) Noise isolation. I think these are the best noise canceling TWS earphones on the market. Noise reduction, by the way, is regulated through the application, as well as using sensors on the headphones themselves. Naturally, the suppression is not 100%, but all the most annoying sounds are not heard (metro, highways, malls)
2) Sound. I have previously owned headphones of this brand and in this case I was surprised. All frequencies are open, the vocals are clear, nothing hisses or squeaks. The headphones are very versatile, which I like very much as a music lover. The lack of AptX and LDAC doesn't bother me. I think that all this makes absolutely no sense in this type of headphones. Especially when Apple Music, . Music or something like that is used as the source. Moreover, my phone, paired with headphones with LDAC technology, almost burned out from overheating))) I always have the priority of sound quality (AAC) in conjunction with Apple Music - there is plenty of pleasure.
3) Design. Against the backdrop of 100 million times recopied AirPods design and some faceless "circles" these headphones look very interesting. At the same time, the design is functional, which causes even more delight.
4) Working time. In general, I very rarely wear headphones even for 3 hours in a row, but on one weekend I decided to take a walk for 30 kilometers. During this walk, I managed to find out the operating time - 4 hours 50 minutes (AAC + Noise reduction + Apple Music + Some calls through the headset) . The final operating time will depend on a variety of factors, including even the weather outside. Overall I'm satisfied and I think most won't need more.
