If you are looking earplugs to sleep quietly, with no sound reaches disrupt your sleep, it is not this article for you. This kind of caps is rather suitable for construction sites or noisy sites They reduce sound without the hide completely. Moreover, after some research, it turned out that it is impossible to have absolute silence with earplugs (as sophisticated as they seem to be). Anyway, I still put 2 stars, because the presentation is neat and fast shipping. The caps are comfortable and do not interfere with sleep.
