Alpine PartyPlug earplugs attenuate the higher tones a bit more. These earplugs offer good protection, don’t make you feel isolated and allow you to hear conversations well. They are comfortable for hours and the music also remains properly audible. If you for instance use the earplugs for going out or an occasional festival, the PartyPlug is a good choice for you. But if you go to festivals or concerts to really enjoy the music, the PartyPlug Pro Natural makes the difference between good and outstanding musical sound quality.
