We continuously evaluate the 8 steps of our production cycle (molds, assembly & treatment, welding, debarring, stainless steel rings, testing, packaging, and our final products) and innovate in each of these 8 steps. Because of all the improvements that we have made, we can now lower the prices of our current products by 30%!

User experiences

Control your volume!

Sometimes places are just too loud. Like that club where the bass is blasting or those infuriating people screaming into their phones on the train. Get some peace of mind with Knops. Need some focus? Isolate yourself with setting 4. In a bar and finding your surroundings a bit too loud? Filter them out with setting 2 or 3.



We don’t only let you control sound. Knops is made of high-quality material that makes our product very durable. Also, every Knops is delivered with three sets of foam plugs (small, medium and large). This ensures that you have the perfect fit for your ear canal. Our sleek design is the icing on the cake. With it, you can wear your Knops all day, every day. No matter what situation you are in. Just choose the Knops that match your style!


We’re here to protect your ears

Knops are real lifesavers. 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 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.
