Are these just regular earplugs to reduce noise? Why do they talk about "The richness of music is preserved", how can earplug preserve the richness of music? Am I missing something here.
gabriel-danA common use case for earplugs is wearing them to concerts, where the volume level might be too loud for some. Some cheap earplugs will block out noise unevenly across the spectrum, which results in loss of detail, warmth, nuances, etc in the music. It is advertising that this won't do that.
