There are always those times in life where we just need some peace and quiet. For some people, blocking outside noise with headphones and music isn’t the answer to complete focus. At the same time, there are plenty of instances where we just need to get closer to something to hear what’s going on. Sometimes our ears just aren’t good enough.

It sounds like we’re complaining here about not being robots that probably have control over what they hear and what they don’t hear. Knops has raised over 3x its goal on Kickstarter, and can give us those abilities without the need for batteries, electricity, or apps.

Controlling the volume of your life definitely sounds appealing. Loud babies on a flight? Not anymore. Asked to lower the volume on the TV at home? Not a problem.

But how do these things work without some sort of electric power source? Natural acoustic resonances are used to tune and acoustic friction is used to dampen sound waves.

Each pair of Knops has four steps. Adjusting to step one allows you to hear what you hear normally. Step 2 reduces the volume to filter the noise of a city, step 3 adjusts the volume to a live music setting, and step 4 creates a silent environment ideal for working. Easily switch from step to step with the knob, and no need to charge them when you get home every day.

Knops are meant to fit across a wide range of ear sizes, and are also meant to stay snug inside your ears. The plug, shape of the base, and the little zeppelin shape come together to ensure no movement from your ears no matter how much jumping or fast head-turning you do.

The design of Knops is based on a classic round volume button with an inner cone shape. Materials include gramophone (available in white or black), ring material (stainless steel or gold plated), and knurling (smooth and knurling textures).

As mentioned above, no electronics, batteries, or apps are involved in this product. While engineered using good old physics, we can appreciate the simple makeup and experience of these ear buds.

In addition to volume control, Knops protects your ears from extreme or harmful sounds. Knops can also be cleaned safely. No corrosive materials were used in production, and can therefore be exposed to water for cleaning purposes.

Knops start at $62 on Kickstarter for delivery this November. The team plans to ship every pair of Knops with a nicely designed pouch for your convenience.
