During a flight pressure inside the passenger cabin fluctuates and if you are wearing earplugs the static pressure between your ear drum and earplug can cause pressure on your eardrum and can cause pain.


Otifleks Flier is designed with a pressure equalizing micro filter which slowly equalizes pressure on both sides of the earplug and prevents pain caused by pressure changes.


Otifleks' Micro Filter is designed to offer maximum attenuation while still allowing pressure to equalize on both sides of the earplug.


Flier's thermo-active material offers superior comfort by matching your body temperature within 4 minutes, conforming to the unique bends, turns, bumps and twists of each individual’s ear.


Utilising the latest findings in ergonomic design and harnessing the power of thermo-reactive elastomer, the minimalist size of the Flier leads to maximized comfort, blocking sound whilst you sleep on your flight..


Tested and Certified

Otifleks was developed and manufactured only subsequent intensive consultations from leading physicians and medical professionals. They conform to Australian and European Union regulations.





Otifleks’ unique micro filter reacts to pressure changes while protecting your peace and quiet.


You never know what will sit next to you in a flight, it could be a crying baby or a loud talker. Otifleks Flier is designed to block noise while still protecting you from pressure changes.
