The ProGuard Lin-Ear PR20 Music earplug features a re-useable 19dB linear attenuation filter that is CE approved to EN352-2:2002. The filter fits neatly into soft flexible silicon eartips (2 sizes available, standard and small) that provide comfort and durability even after long periods of use. Fitting deep into the ear canal the earplug is discreet and has no protrusion allowing the user to wear headphones or other types of headwear if required.
Specifically designed for musicians, DJ’s, sound engineers, concert-goers and music enthusiasts, the Lin-Ear PR20 will enable the user to listen to loud music in perfect clarity, yet maintain the live atmosphere without risking hearing damage. The PR20’s advanced membrane technology acoustic filter will provide natural undistorted sound with minimal occlusion effect* that’s often associated with earplugs. The vented design of the Lin-Ear allows the trapped sound to escape through the acoustic filter as if your ear was open, leaving you with the most natural sound available.

*Occlusion is caused by sound carried to your ears through bone or cartilage conduction, normally this is unheard and escapes through the open ear but if your ear is blocked by an earplug the sound becomes trapped and a booming low frequency effect will occur causing an uncomfortable sensation.
