Safe N' Sound

Since I'm an engineer, things like this tend to spike my interest. I decided in the best interest of my ears to purchase some ear plugs, Vater Safe 'N Sound Ear Plugs to be more specific. I haven't tested them yet, but I was curious with the red and green filters what would be the best for my purpose. The package lists the dB reduction for the frequencies of 125,250,500,1000,2000,4000, and 8000 Hz. This is not very customer friendly. This information is better displayed in a chart (see above).

The chart indicates that there is a bias in the higher frequencies to be filtered. I'm hoping to still hear vocals. A reasonable estimate of frequency for vocals is between 100 and 1000Hz. Thus, the frequencies that are significantly reduced should not affect my ability to hear the vocals. Well, we will see.
