Promising review: "I love this product! Every couple of trips, no matter what tricks I try, I cannot clear my ears. The ear pain is immense at takeoff (I completely understand why those babies and toddlers wail!), and then I'm hard of hearing for days. With these, that has never happened. A few other people near me had ear pain and I did not, so I was very grateful I'd bought this product." —Amy Clark Get a pack of three from Amazon for $14.25 or one pair from Walmart for $6.84.
