If you have felt pressure in the ear and pain even at the start of the flight and during ascent we recommend inserting the ear protection before the start and to remove it only after approx. 30 minutes after the start of the flight. The pressure conditions in the cabin normally do not change at cruising altitude till the aircraft begins to descend. During flights of less than an hour and half duration, we recommend wearing FlightSafe during the entire flight, especially since the ear protection additionally works to reduce noise.
