With six sound options, the Big Red Rooster White Noise Machine offers a variety of soothing ways to mask background noise—whether you’re trying to fall asleep, focus on work, or simply just relax after a long day. You have the choice to leave it running uninterrupted, or set it on a 15-, 30-, or 60-minute timer. The top-rated white noise machine, which has more than 8,200 five-star reviews on Amazon, is also battery-operated, so you can enjoy the tranquil sounds of rainfall, running streams, ocean waves, and white noise when you’re traveling, too.
“I got [one] for my son who has sensory needs, but also has a really loud room, that it’s even hard for me to fall asleep in there,” explained one reviewer. “My son likes the ocean sound and has tremendously helped to drown or all that other sounds from the highway out his back window.”
