How does
Limousine Knops work?

Well, first of all Knops uses no electronics, no apps and no batteries. Instead our earbuds are acoustically engineered.

The real sound is filtered using good old physics. With the help of computer simulations and real-world prototypes tested in acoustic labs, we tuned Knops. We spent a lot of time fine-tuning the sound, so we can provide the best quality sound at every volume level.

Working with the natural response of the ear canal. We even managed to create a similar reduction in dB across all the frequencies. Creating a very flat response curve. This means that sound travels through all the four steps with minimal distortion. We are mimicking the natural resonances of the human ear. So crystal clear sounds, vibrant and natural.


4 filter settings

Each pair of Knops has four steps. Adjust the Knops to step one and you will hear what you hear without plugs. The real kicker enters the stage when you switch to the other three steps.

Step 1 has no filter and you’ll experience the world in all its noisy glory.

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. Four different modes for basically every audio situation.

How to use Knops

We made five very short videos to bring you up to speed on how to use Knops the right way.
