Pressure-regulating earplugs for a comfortable journey The Alpine FlyFit earplugs have an excellent, well-designed fit and are ideal for relaxing on the go without unpleasant ear pain. Especially during takeoff and landing, an unpleasant feeling of pressure on the eardrum can quickly develop, which can be minimized with the help of earplugs. The filters act like a kind of valve, ensuring a consistent and even pressure balance between the outside world and the middle ear. Alpines multifunctional earplugs also effectively dampen background noise, promoting peace and relaxation. Conversations remain intelligible thanks to the Alpine Acoustic Filter, making it easy to order a drink from the flight attendant. The package contains two universal thermoplastic ear defenders, an insertion sleeve, and two acoustic filters. An Alpine Cleaner and a plastic storage box are also included.
