I wanted some reusable hearing protection for work, instead of the yellow foam plugs.
First time I tried them out at home, they were kinda hard to insert and even harder to get out, for a minute I thought it was stuck. And my ears kinda itched afterwards. When inside your ear, don't accidentally tap the plastic tubes that go inside the rubber plugs as it resonates very loudly inside your ear canal. I also didn't feel as if they would offer the protection I wanted, and even seemed to make certain sounds appear harsher, although that might be a psychological effect after not being too impressed by now.
I have them as a backup pair now, just in case.
But I will be sticking to old school yellow foam plugs. I feel this product might work differently for different people, that's why I still gave two stars. One last thing: the carrying tube that comes with it has a bottle opening feature, although it chips off pieces of aluminum when you use it :[
