Limousine Analogue Adjustable Earplugs Knops Smooth – Black

Knops Earplugs are the world’s first fully analogue, adjustable high-fidelity earplugs that let you control sound in real time like a volume dial. Made in the Netherlands, they offer four settings—from clear, unfiltered audio to ~30dB sound reduction—for personalized hearing protection in any environment.

A Volume Dial for your Ears

Introducing the worlds first fully analogue, adjustable high fidelity earplugs – the Knops Earplugs, made in the Netherlands.

Designed for people who value their hearing, Knops earplugs put the power of sound control at your fingertips without batteries or apps. A similar reduction in dB across all frequencies creates a very flat response curve meaning music can be enjoyed clearly as intended but at a lower volume.

With 4 acoustically tuned settings (0dB, ~10dB, ~20dB and ~30dB reduction*), users can fine-tune their listening environment in real time, without removing the earplugs or fiddling with different filters. A simple turn of the outer drum, as you would a volume dial, adjusts the filter of the earplug. Each ear can be adjusted independently.

What’s Included?

Knops earplugs are supplied with silicon ear tips plus 3 different sizes of foam tips to ensure users can achieve a good in-ear seal. Each set comes with a carry case, supplied in retail display packaging with instructions. 2 year limited warranty, excluding the tips.

The 4 Settings of Knops

The Knops earplugs consist of 4 settings that help you reduce sound.

Step 1 is the only setting that does not filter any sound and lets you hear everything loud and clear. Although this step doesn’t use a filter, it is acoustically tuned.
Step 2, 3, 4 filter ~10dB, ~20dB and ~30dB respectively.*
