If you've ever flown on a plane, you've felt the discomfort of ear-popping and pressure changes, as well as that annoying mechanical humming that never goes away. Although electronic noise cancelling headphones work, they consume battery power and can get uncomfortable after a short amount of time. The Crescendo Fly Ear Plugs suppress background noise and are among the most comfortable ear plugs.The Crescendo Fly ear plugs feature the patented filters designed by Dynamic Ear Company, which suppress annoying background noise, but still regulates the air pressure during the departure/arrival. By slowing down the rate of pressure change between the ear and cabin, the flight goes from an annoying, uncomfortable hassle to a peaceful and comfortable time on board.Product sheet for the Crescendo Fly Ear PlugsAdditional Features:Weight.09 lbsDimensions6.3 x 3.5 x .9 inEartip ColorWhiteEartip SizesMedium, LargeFilter Type 20 dB average dampingWarrantyTwo year limited manufacturer warranty
