These reusable QUIES earplugs are special earplugs made for air travel.

In some cases, the sudden change in pressure on the eardrum can cause severe pain (landing, tunneling, pressure changes).

This protective earplug has an exclusive patented ceramic filter that naturally regulates the flow of atmospheric pressure on the eardrum.

This porous filter allows a gradual exchange of air over several minutes to allow the eardrum to gradually adapt to the new pressure rather than being shocked. This patented process was developed with the help of US Navy pilots.

Instructions for use:

Insert the ringed earplug into each ear without forcing it before pressure changes (before take-off and before descent in the plane).
Remove the protections 5 minutes after the return to normal pressure

In the air:
For any short flight, they can be kept on until landing
For a long haul flight, it is preferable to remove them during the journey and advised to reposition them before the descent
The plugs are reusable and sold in pairs in a rigid box for easy transport.
