I tested the QuietOn 4 sleep earbuds to see if they can actually improve your rest

The HearFit QuietOn 4 are a very compelling pair of sleep headphones on paper. At a time when everything requires an app, makes you go through an annoying setup process and blasts you with notifications, these buds make a simple promise: Stick them in, enjoy some active noise cancellation to drown out those annoying ambient sounds and enjoy a peaceful night’s sleep.
