These look like attractive and effective earplugs.

In December of 2014 a group of four friends (Koen, Quinten, Arjen and Richard) in Amsterdam resolved to design attractive and effective technology for hearing protection and in April 2017 a Kickstarter campaign was launched with a target of €30,000 . As at 12 May, 2,948 backers pledged €258,707 and Knops is on the journey.

Knops is a volume button for ears. The acoustic hearing solution allows for full control over the surrounding sounds you hear throughout the day.

Knops has four gradient steps which allow you to hear only what you want to hear. Step one allows sound which would be heard without plugs. Step two reduces the volume to filter the noise of a vibrant city, step three adjusts sound for a live music level and step four creates a silent ambience.

The days of plugging and unplugging earbuds are gone with Knops and the risk of losing your earbuds are significantly reduced. Knops are engineered to use in multiple environments which solves the old problem of earbuds falling out.
