Review on Upgrade Your Music Experience with XiaoMi True Wireless Earphones 2 Basic - Longer Battery Life and Superior Sound Quality (White, International Edition) by Akmal Ibrahim Alex ᠌

They don't stay in the ears very well, they fall out if they are touched. Quite large in size, although you get used to it with time. Not vacuum, but liners, and therefore in the subway you won’t hear much in them (this is a big minus), although everything is heard well on the street and in the train. The touch and absolutely useless touch button for calling the voice assistant is very disturbing, I have never used it, and the Chinese could simply switch tracks instead :(
