I’m one of those people who can’t fall asleep without a fan running — so when I travel, my Babelio White Noise Sound Machine is always at the top of my packing list! It’s tiny (it fits right in my pocket!) but blocks out noise like a champ. With 15 non-looping sounds — including fan, rain, and waves — and a rechargeable battery, it’s the ultimate travel sleep essential. I truly don’t leave home without it!
