Unfortunately, the plastic is not flexible enough, so that it is broken at me on the second day of the application behind the big bow. Have him quite normal when putting bent slightly apart to make it easier to get him over the head, which one indeed makes every hearing protection, since there is no other way, and he is broken. The point at which it is broken, is a bit thick and reinforced with a small dock, but that's what makes the place is not flexible enough to join the constant movement.
Furthermore, the hearing protection is a bit too large. I had between mind and Ironing about 2-3cm air. There are other models that can be adjusted in size.
Conclusion: No buy recommendation !!
