Mack's Flightguard earplugs allow the ear to adapt to pressure changes, making them suitable for air travel. Noise reduction level: 26 dB.
How to Use:
- Before inserting the plugs, with your mouth closed and your nose pinched, exhale gently to clear and normalize any pressure in the ear.
- For best results, insert the plugs before takeoff and remove them only after landing and opening the airplane cabin door.
- The plugs can be removed during the flight, at cruising altitude, but must always be inserted 1 hour before landing.
- Pull on your ear to straighten the entrance of the ear canal.
- With the other hand, hold the plug's stem and insert it with circular movements until it fits snugly in the ear, creating a seal.
Precautions:
- Remove the plug gently, making circular movements, to relieve and allow air to enter gradually.
- Quickly removing the plug can damage the eardrum.
- Do not insert the plug too deeply into the ear; leave the stem easily reachable.
- Do not use for sleeping while lying down.
Additional Information: Very soft and flexible flight plugs.
