PresSilence Earplugs / earplugs

PresSilence Earplugs
PresSilence Earplugs

The ‘PresSlience’ earplugs are designed to solve the problem that conventional earplugs are hard to use. It consists of a rubber body, a frame and a stick. Initially, the rubber is tighteed and can be easily placed into the ear canal. After it is placed into your ear canal, press the stick and it will spread the rubber to conform to the shape of your ear, thus to isolate you from noises. The stick will be automatically locked by the frame. When you want to take off the earplugs, press a button on the frame and the stick will bounce back, leave the rubber tightened up again so you can take the earplugs off with no hussle.
