SANOHRA fly - Soft landing for your ears

This is how ear pain is caused while flying

More than half of all air passengers know the uncomfortable feeling of pressure or pain in the ear that occurs mainly while landing. This is triggered by the rapidly increasing air pressure. If the Eustachian tube is not able to generate the active opening that is necessary quickly enough, a high, relative low pressure is created in the middle ear. This pushes the eardrum in the direction of the middle ear. This causes ear pain and bleeding, in extreme cases.

designed to protect the ear


SANOHRA fly
has been specifically designed to protect the ear from rapid and severe changes in air pressure. A pressure regulator (apc), which is integrated into the earplug, regulates and slows down the pressure changes in front of the eardrum.


Tested by the passengers themselves


More than 500 passengers participated in a user acceptance study carried out by the Institute of Marketing and Management of the Leibniz
University Hannover for the Hannover Airport, TUIfly.com, the airport pharmacy and the manufacturer, the Innosan GmbH.

The group of test persons who were particularly affected by ear pain while flying, achieved an average pain reduction of 6.2 points on a ten-point pain scale by using SANOHRA fly.

Over 90% reported an improvement in discomfort level.

In the group of test persons who previously rated their ear pain levels as moderate, around 80% of them were completely free of pain after using SANOHRA fly .
About 80% of all the test persons would recommend SANOHRA fly to their friends.

SANOHRA fly not only protects your ears during the flight, but also in all situations where strong changes in air pressure could trigger earaches, such as while travelling on mountain railways or in fast elevators in skyscrapers.
