I was worried that they would not fit, but they got up in both ears without problems, in my case it is not critical (it is better to control what is happening around than to completely block it), but you won’t walk like that. Some pros: Beautiful, original, tactilely pleasant, the application, control, Indoors, on a quiet street - it's better, indeed, the tracks sound with nuances that I didn't catch before, in a city on a busy street, in transport - worse. Got cons: The earpiece fell out three times, managed to catch it 2 times, if you just put it in (as in advertising), there is a chance of falling, the interlocutors can hear me either in an empty room at a great distance from the microphone, or with a crash, loss of sound, on the contrary, I can hear it well.
