Knops are a new pair of adjustable earplugs looking for funding on Kickstarter that claims to be “the volume button for your ears”.
Each pair of this adjustable earplugs has four steps. Adjust the Knops to step one and you will hear what you would’ve heard without plugs. But the real kicker enters the stage when you switch to the other three steps. Step 2 will reduce the volume to filter the noise of a vibrant city, step 3 will adjust the volume to a live music setting and step 4 will create a silent environment ideal for work. Four different modes for basically every audio situation.
The Dutch startup has based the design on a classic round volume button, with inside the shape of a gramophone cone, showing the link with volume and sound. This design in high-quality materials in combination with the option of various colors and trims makes Knops an accessory item which fits your personal style.
“Instead of using electronics to try and synthesize something artificial, we’re taking the actual soundwaves that come into your ear, and modifying them,” explains Arjen de Jong, founder and head of technology of the startup, who has a PhD in acoustics.
Knops are available on Kickstarter now starting at $62.
