We use this product, ear planes, on every flight - this product helped us with pain and pressure while in-flight. I will never fly without these - the adults in our family use the adult plugs, and the children use the children plugs. Children will need assistance to make sure they are properly inserted but they are not uncomfortable. I would suggest placing them in the ear prior to take off, and leave them in the entire time. Hearing is a little muffled, but not too bad, and it does quiet the sounds of the loud plane - however, in-ear plugs for music will not be able to be used when using the ear planes, but it's a small price to pay for piece of mind. Before I used these, my ears would hurt for hours after a flight, and pained me a lot in-flight. When I use these now, I don't have any discomfort or pain.
