It better use the cheapiest ear plugs.
We had the worst neighbor over us, so we're getting literally sick since he arrived to live upstairs, so I've been trying one and another ear plug, and every ad says that is the best, but until now anything has worked, not even this one that has so many great reviews and that's why I got it. It turn out no, no isolation, no comfort, they carve a lot. I'm sure that could work for another people but form me definitely no, at all... I just wasted my money and time and hopes. I made the comparison with the foam ear plugs that cost 1 dollar and I think it covers a little bit better the sound. These earplugs I bought don't reduce almost anything.
