The Knops hearing solution will ship worldwide. The shipping costs depend on the country the product will be shipped to.

No. The Knops hearing solution is a fully analog and acoustic device and doesn’t need batteries. So you can use it all the time without worrying about dying batteries.

This version of Knops will not support playing music. But we do have plans to develop a version that supports playing music.

The Knops hearing solution is designed to reduce volume by up to 10dB, 20dB and 30dB (decibel levels are indicative, the final product decibel levels may differ slightly from these indications).

Yes. You can control the volume independently with the volume button on each ear.

Yes. Because of the volume button, you can instantly control your volume. So you can open up the volume and talk.

We have done a lot of testing to ensure quality of fit across a wide range of ear sizes, so we are confident the Knops will fit almost everybody.

Yes, you can use the Knops at the firing range. Just make sure you put them in step 4 before shooting so you have maximum protection.

The Knops hearing solution is designed to reduce volume across the frequency range. Which helps prevent development of tinnitus and hearing loss. That being said, it is not designed to help with existing tinnitus other than preventing further development of tinnitus.

No, Knops are ergonomically designed to stay snug inside your ears. With the help of the plug, the shape of the base and the little zeppelin shape at the back of the base the knops will stay inside your ears no mather how much you jump or how fast you turn your head.

They weigh less then 10 grams per piece, so around 20 grams per pair.

No cancelation with electronics, instead we use natural acoustic resonances to tune and acoustic friction to dampen sound waves. Knops does provide similar results to noise canceling technology, as it allows you to lower the volume in multiple steps. The last step is great for isolation.

Knops uses multiple tuned acoustic filters. The filters use natural acoustic resonances to tune and acoustic friction to dampen.
This means that real world sound is filtered, the same quality is being kept and the volume is reduced depending on the volume level you use at that moment.

Yes! We where designing a nice pouch to ship with every Knops. Now we have a stretch goal for a High-end hard cover Case. Check our update for more information

Yes you can clean Knops. We don't use corrosive materials, therefore it can be exposed to water for cleaning. We will add a cleaning guide with Knops for the exact details.

Yes, Knops can help you a lot. Knops allow you to turn down the volume of your environment in multiple steps to your liking. This way, Knops can remove noise and lower the volume of loud sounds.

We actually didn't developed Knops for sleeping specifically. That said, we don't see a problem wearing them while sleeping on your back. We didn't tested Knops for sleeping on your side, so we cannot comment on how comfortable they will be if you are sleeping on your side.
