Is there anything worse than checking into a hotel room and tossing and turning all night because of loud noises from neighbors or city streets? With this portable sound machine, you can drown out the sounds of people, cars, or snoring companions. It was designed for parents to help soothe their babies on the go with any of its 10 sounds (white noise, ocean, rain, water, wind, dryer, fan, rock-a-bye, heartbeat, and hush), but works just as well for adults who could use a little help falling and staying asleep. It weighs just four ounces and fits in the palm of your hand; at around the size of a tennis ball, it’s easy to stash into any backpack or tote.
