Earplugs for festival, concerts and going out. If you go to a concert or festival you particularly want to enjoy the music. But you don’t want to incur hearing damage or a permanent ringing in your ears. Especially for music lovers, there are now the Alpine Party Plug Pro Natural earplugs. These earplugs have special rectilinear AlpineAcousticFilters. This means that the music is attenuated equally at all frequencies.
