Alas, there were more cons and I did not manage to justify them after a month of daily use of these headphones. The biggest disadvantage is that when you disconnect the headphones from Bluetooth, after reconnecting, the headphones do not connect to each other, but one works. Simply put, the second earphone cannot connect to the first, main one. Therefore, you have to do a complete reset of the headphones, put them in a box, take them out and connect again, and this whole long procedure, which takes 1.5 minutes, does not guarantee that the headphones will play in sync. Sometimes you have to do it several times, which is very annoying when you want to immediately get the headphones out of the box, put them on and turn them on, but instead you have to mess around. Many people talk about this bug in the reviews, it is definitely a software bug, not a marriage. The second drawback is the sound. I'm used to good sound, because before these "ears" I always had Sennheiser and compared to them Xiaomi sounds an order of magnitude worse - there is not enough bass, sound density. By the way, I listen to different music and do not belong to bass lovers, but the Xiaomi sound disappointed me a lot. Even wired Sony for 600 sounded much better. It is impossible to listen at full volume due to high frequencies. Also, the noise isolation of the headphones is not good. The noise in the subway is audible even at high volume, not to mention low. And last but not least, the box. It is very flimsy, slippery and uncomfortable. It slipped out of my hands three times in a month, as it is very inconvenient to open it, because there is no hole to pry with your finger, and the plastic is very slippery. And the lid itself is held, sorry, on the snot and has already loosened. Oh yes, the microphone - when talking on the microphone, the interlocutor hears very poorly, so in most cases you have to turn off the bluetooth, take off your ears and talk on the phone.
