D'Addario Pacato hearing protection is a reusable, universal
sized audio filter designed specifically for musicians and music
enthusiasts. While traditional earplugs can sound muffled and
unnatural, the Pacato filters provide full frequency, enjoyable
audio at safe listening levels. The exclusive design offers an
open air passage to the ear, minimizing occlusion effect (low
frequency emphasis), while keeping the ear ventilated for
unmatched comfort.
