A new Amsterdam-based kickstarte has launched, which aims to act as a volume button for your ears.

Called Knops, the wireless, in ear device alows wearers to adjust the sound of life itself. Just imagine the possibilities, like….no crying babies on the airplane, for example! Essentially, one can instantly control real world volume, just like with the volume button on your headphones.

Each device comes with 4 settings: the first being regular, second for the sounds of a vibrant city, third for the sounds of a live concert experience, and fourth for a silent environment. The design is based around the “classic” round volume button look and is available in a variety of colors and trims for full personalization.
