These devices are simple, even as companies keep adding bells and whistles. They now come in all shapes and sizes, with options for playing different noise frequencies and soothing nature sounds—whether you need one at home or a portable model for life on the go. And they’re not just for kids or babies; if, like me, you want to quiet your inner monologue and finally drift off, this guide is for you.
We've tested everything: the best sleep trackers, sunrise alarm clocks, mattresses, and extreme alarm clocks. Check out all of the WIRED Reviews team's sleep coverage for our recommendations. Note: If you're buying for a child, keep sound machines to no more than 50 decibels and farther than 200 centimeters (6.5 feet) from where your baby sleeps.
Best White Noise Machine Overall The Snooz white noise machine focuses on one thing and one thing only: white noise. Its sound is generated by a real fan, not just fan sounds. There's no need to push extra buttons or fidget when you'd rather be falling asleep.
Its design is simple, and there's no overthinking this device—it's got ease of use down pat. Simply plug it in, press the power button, then twist the mesh sleeve to increase or decrease the volume. It's also meant to be placed away from the bed, in a more central position in the bedroom, rather than on a nightstand.
This helps project the sound more evenly. —Julia Forbes Specs Sound options White noise Timer No Alarm No Light No Size 5.6 x 5.6 x 3.2 inches Colors Gray, black Best White Noise Machine With Sleep Tracking WIRED’s resident wearable tester, Boutayna Chokrane, tested this clock for her sleep trackers guide. (Read her full review here.) This brand-new white noise machine also doubles as a sunrise alarm clock and a passive sleep tracker. It uses motion-based tracking to monitor your sleep from your nightstand. The data focuses on the essentials—sleep duration and stages—and appears in interactive visuals.
There are no cameras or microphones monitoring you as you sleep, and best of all, your data isn’t locked behind a Hatch+ membership. The machine also features adjustable volume, fade-out timers, customizable full-color light scenes, a gradual sunrise light to wake you gently, and a sunset wind-down light to help you prepare for bed. For sleep-inducing sounds, it offers white noise, nature sounds, sleep stories, and guided meditations.
