Limousine Adjustable Earplugs Knops Smooth

A Volume Dial for your Ears

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

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.*
  
• Setting 4 is certified as SNR 28dB

Where to use Knops

Thanks to their quick adjustment, Knops give you a highly adaptive approach to noise and volume adjustment on the fly.
