CRESCENDO / FLY 20 N

CRESCENDO / FLY 20 N are pressure-adjustable earplugs designed specifically for air travel. Featuring filters designed by Dynamic Ear and advanced membrane technology, they reduce ambient noise, ensuring a calmer and more comfortable flight.

■The membrane gently adjusts to changes in air pressure during takeoff and landing, reducing strain on your ears. Because it's not electronic, it doesn't require batteries and can be used throughout the flight.
