Earplugs are nothing new. They’re found in the ears of workers on airport tarmacs, kids at concerts and in many a bedroom where one partner uses them to drown out the snoring of the other. But earplugs that use electronics to help drown out the world around are, in fact, a relatively new invention. A new pair of smart earplugs from Hush takes a novel approach to delivering peace through your ears. The earplugs fill your ears with soothing sounds. You can choose from a variety of ambient sounds like the woosh of space, the roar of a waterfall, the hum of an airline cabin, or the patter of rain.
