I can't wear it because I have to run, and I'm sure it will fall off. I don't know if you have ever used closed headphones. Feel very relaxed when exercising. Closed headphones block your ears, which is very uncomfortable. I can't exercise at all. It's uncomfortable and hot.

Then, I think your understanding of the meaning of missing sound is biased. I can understand what you mean when you listen to music in the library, for fear that the loud music will affect others. Then I'm going to say that closure means inward closure, not outward closure. In other words, closed headphones and open headphones are the same. If they are too open, others can hear them. As long as they can make a sound, they will make a sound like the outside world, and your ears can't be blocked, okay?

In all cases, the mx680 of Senhai or other types of 680 are recommended.
