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.
