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.
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.
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.
