Specially designed for travellers Flitemate earplugs will add to your comfort whilst flying. They reduce noise and slowly balance cabin pressure changes that can cause pain and discomfort. Flitemates are also good for people that suffer pressure changes such as climbing a hill in a car, skiing and when high-speed trains pass in tunnels. Just insert the FliteMate Earplugs securely in both ears before takeoff and do not remove them until the plane has reached cruising altitude, then be sure to reinsert the plugs before the plane begins its descent to land. Since the FliteMate plugs also greatly reduce the background noise on the plane, your trip will be more comfortable if you just leave the plugs in your ears throughout the trip.
