Noise cancelling earplugs

QuietOn is a Finnish company that has invented something as nice as earplugs that actually work.
Most of us have tried to be bothered by noise or snoring when sleeping. Unfortunately, normal earplugs just do not work as well as intended. Either that or they fall out.
But QuietOn believes to have invented earbuds that actually shut out the sound as seen on noise cancellation headsets.
Unlike earplugs, QuietOn blocks low-frequency sounds, thus providing a peaceful sleep.
QuietOn is not for sale yet, but you can pre-order them on their website.
