Most high-tech: SNOOZ White Noise Sound Machine

This fan-powered white noise machine looks like a smart speaker. Inside, however, a powerful fan pushes air through a series of vents to create a steady, calming whoosh of moving air without creating a draft like a typical fan. Touch controls on top—and companion controls in the app—allow you to choose from 10 different power levels. Rotating the fabric-lad case allows you to control the sound’s pitch, so you can really dial in the perfect sound for canceling out a snoring partner or the pesky 5 a.m. garbage truck noise.
