Designed for musicians and music enthusiasts, the ACS Pacato earplug is one of the most discreet universal-fit plugs available on the market today. Sitting comfortably in the ear with no protrusion, the Pacato can be worn underneath headsets, or other ear coverings, and in any situation where discretion for the wearer is desired.

Pacato earplugs use a vented design, which offers a flatter frequency response than other earplugs, and an open air passage to the ear in order to minimize occlusion. Occlusion happens when your ear canal is sealed. Try this: block off both of your ear canals with your little fingers, and start to speak. Your own voice will start booming inside your head. Vented designs minimize such an effect.

Pacato earplugs come standard with two sets of differently sized ear tips - medium and large - and one set of audio filters. According to the manual, the audio filters come pre-fitted with the larger ear tips. But this was not the case: audio filters were plugged into the medium pair. As those ear tips won't work correctly without the audio filter fitted, always check if filters are present before wearing your preferred size!
