World's First Volume Button For Your Ears

Finally.

From websites:

Knops is an adjustable analogue acoustic hearing solution that will give you full control of the sounds surrounding you.

It lets you adjust the volume of life itself.

Whether you need silence while you're studying in a loud environment, or you want to tune down the noise of the vibrant city around you, the Knops can do just that.

It's like a world audio volume button that you can adjust.

Finally, you're in control.

Each pair has 4 steps:

• Step 1 is what you would hear with no plugs

• 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

• Step 4 will create a silent environment ideal for work

The Knops is available in different colors and trims to match your style.

It occurred to me that these could double as an emergency trephination guide in a pinch.

But that's prolly just me.
