Knops is engineered in such a way that the earplug mimics the natural response of the human ear.

You can enjoy the real sound that isn’t manipulated by electronics and apps.

We think it’s time there is a quality analog solution to control volume that can be used in different situations. From festival to exam, city life to working at the office. That’s why we developed Knops, a literal volume button for your ears. We're now on Kickstarter with our product, you can find us under Knops.
