When Goodnight Moon author Margaret Wise Brown wrote “goodnight stars, goodnight air, goodnight noises everywhere,” it’s unlikely the noises she imagined were jackhammers, sirens, or a snoring partner. If you, like me, are a light sleeper in a busy world, an uninterrupted night of rest can feel like a fairy tale.Sleep headphones can help.

After years of testing many sleep headphones that proved to be a nightmare, I’ve found two pairs that help me sleep like a baby: the Soundcore Sleep A20 and AcousticSheep SleepPhones Wireless.
