Key benefits - Reduces ear pain during altitude changes by slowing air flow into the ear canal and equalizing pressure between inner and outer ear for more comfortable takeoff and landing. - Lowers background noise (up to 30 dB) to reduce engine roar, cabin noise and nearby conversations so you can rest, concentrate or sleep. - Comfortable for long wear: soft silicone and an ergonomic two-flange shape create a secure seal without itching or discomfort. How it works - Pressure relief: a specially designed vent controls the speed of air entering the ear canal, allowing gradual pressure equalization and preventing sudden pressure changes. - Noise reduction: the two-flange silicone design forms an effective seal in the ear canal to block excessive noise while maintaining awareness of important sounds. Note: complete elimination of all noise is not guaranteed. Features & materials - Noise reduction: approximately 30 dB. - Shape: two-flange silicone plugs for a reliable seal and secure fit. - Material: soft, skin-friendly silicone for prolonged comfort. - Case: compact aluminum storage case with a carabiner for easy attachment to bags or keys. - Construction: lightweight design suitable for travel. Performance & fit - Ergonomic design adapts to the ear canal for long-term wear without falling out or causing irritation. - Designed specifically to regulate ear pressure during altitude changes and to reduce cabin noise during flights. Practical use scenarios - Air travel: use during takeoff and landing to reduce ear pain from pressure changes and to lower engine and cabin noise for a more comfortable flight. - Sleeping or resting in transit: wear on long flights, trains or buses to block background noise and improve sleep or relaxation. - Busy environments: reduce distracting noise during noisy commutes or in crowded airports while remaining able to hear important announcements. What’s included - Silicone earplugs (pair) and a compact aluminum case with carabiner for secure, portable storage. Note - These earplugs are designed to reduce pressure-related discomfort and lower noise levels up to 30 dB; they are not intended to completely eliminate all sounds.
