Something I rolled too much water) Its pros: Excellent sound, noise isolation (attention) if you choose the right ear pads, it’s normal, you can hardly hear extraneous noise in the subway, but the headphones should sit tightly in your ears, otherwise it won’t work at all. The microphone, according to friends, is excellent, you can hear it well in a conversation, it dampens extraneous noise. Ears! Personally, I have! do not hurt (at work I sit in 1 earphone for almost 13 hours without taking it off). The transparency mode will work, it seems to work fine, but I don’t use it much. The charge is kept for a long time, they are charged from the xiaomi plug (from the phone) instantly, the headphones themselves in the case also charge quickly. You can ate the firmware in the application and the codecs will change: the base one will be AAC, the switchable xiaomi LHDS codec, but it requires Bluetooth 5.2 (I can be wrong here) the codec is excellent with minimal delay, but it doesn’t work for me (it starts, but the signal is interrupted) mi 8 smartphone pro Got cons: The application is in Chinese, now you can’t just download it (files on w3bsit3-dns. Com to help), with the help of another smartphone in your hands with a photo translator, we ate, turn off the Chinese assistant, set up touches and forget about it like a bad dream (although then you get used to and there is nothing complicated there). When switching noise reduction modes, commands are heard in Chinese (playback pauses for a second), but by the voice of a Chinese woman, you can remember which mode is which XD. I have problems with playback after automatic connection (all sounds are played, but spotify, although it shows that the sound output goes to the headphones, it does not transmit / or the ears themselves do not reproduce it is not clear) it is treated by turning Bluetooth off and on. Then everything is OK, usually in the morning.
