I bought these earplugs because I was searching for a hearing protector for the night, be suppressed by the snoring noises, higher notes (baby) stay still clearly audible. The manufacturer's description in this regard is listening on the website very promising. Actually me these earplugs but have more than disappointed. First, the suppression of the snoring sounds nil - I hear my husband snoring completely unfiltered, as without earplugs. Second, the application of ear plugs is not possible with the included applicator, because this just does not fit on the ear plugs. It is to get into the ear canal is possible but difficult. And the absolute horror experience with these earplugs was when I tried to remove them at night, and an earplug was able to slip so far into the ear canal, it was impossible for himself to bring him back out to me. After 20 minutes it was trying to get himself out of my ear, I woke at 02:00 clock in the morning my husband, who just 15 minutes and several painful attempts needed with the tweezers to get the thing out of my ear. This must be said, we are both doctors and we know from the anatomy of the ear canal and have uncontrolled poking around in your ears. My conclusion: These earplugs are harmful because they slip too deeply into the ear canal. This is painful and dangerous from a medical perspective. Moreover, they offer no noise insulation.
