The Knops Earplugs are acoustic adjustable hearing controls that let you easily and conveniently reduce any surrounding noise in just four steps. These hearing gadgets are the first-ever analog hearing solution that's adjustable in multiple sound-level settings (meaning different dB levels). With them, you can easily control the typical noise life and ultimately have a quieter and more peaceful daily routine throughout the busy city life that's commonly found everywhere. That goes for loud cars honking, general traffic passing by, a crowded coffee shop with tons of people talking when you're trying to stay focused on a study piece your reading, and pretty much anything else that might sound loud for you at any given moment.
