"Not to brag, but I'm kind of a white noise machine connoisseur. I've been using them for years and I think the Snooz White Noise Sound Machine ($80) is one of my new faves. It has a real fan inside so the hum is smooth and soothing instead of scratchy. The machine also connects to an app via Bluetooth, so I can stash it under my bed and out of the way, then turn it on and adjust the volume from my phone. I have a tiny room with minimal floor space, so this is a big plus." — Maggie Ryan, assistant editor, Fitness
