When I put on the headphones for the first time in the shopping center (not yet turned on), I thought that everyone around immediately fell silent - the noise isolation is amazing! At the same time, in the on state, the sounds "from the street" can be configured in such a way that you can freely talk and drive a car - everything is heard from the outside. In the gym, with intense loads, after three hours it becomes a little uncomfortable in them - they slip off when pressing while lying on the bench from the fact that the upper bow is too narrow.
