Have you ever experienced the cry of a baby on an entire flight, a stabbing pain in your ears while flying, or ever gotten off of a flight and was not able to hear for hours and sometimes days? Short of getting tubes in your ears… there are no real preventative ways around this discomfort—until now! No Pop is the answer to prevent so much needless suffering while in flight. No Pop is used over the ears while traveling in High Altitudes to prevent the pressure, popping, and pain associated with flying. This apparatus can be made economically and above all-- it works great... especially for kids, sensitive ears, and allergy and cold sufferers. Ear popping may cause damage to the ears so we really need to protect them. Cabin pressure is equivalent to the elevation of Denver, CO. and higher pressures, this is very uncomfortable for most people, especially if one has not had the chance to acclimate slowly.
