What makes the DI-15 different from other earplugs?
DI-15 earplugs are "active"(electronic) earplugs, which means that they do more than JUST block sound like passive earplugs. Passive earplugs affect sound quality and reduce the ability to hear very soft sounds, while traditional 'foam' plugs block sounds and complicate communication altogether. Circuitry in DI-15 earplugs restores sound that is lost when the eartips seal off the ear canals and provide hearing protection when needed. The intelligent technology of these noise reducing ear plugs for dentists allows for 100% natural hearing when sound levels are safe, then automatically protect from damaging sudden or sustained sounds, helping to prevent permanent hearing damage.
