iFi Ear Plugs are fuss-free, 100% pure memory foam, created by iFi to make sure you get a good night’s sleep or take uninterrupted time out for yourself.The iFi Ear Plugs are extremely effective. So much so, that measured noise reduction is even better than top-flight Active Noise Cancellation headphones. The best active noise-cancellation headphones offer on average 25dB noise reduction. This is adequate but does not offer near total silence from ambient cabin noise. Used together, some 62dB of noise reduction to the level of a quiet room is achieved so you can truly enjoy the silence. Eight pairs of earplugs, each pair with a cool transparent iFi storage box.
