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.
