Not only does the LectroFan Micro2 work as a sound machine, but it also doubles as a Bluetooth speaker. You'll be impressed by the overall sound quality, too, which is plenty loud despite its small body. It’s just 2 inches tall, has a full day of battery life, and is capable of playing 11 built-in sounds to help you fall asleep faster. Sounds include five digital fan options, four variations of white, pink, and brown noise, plus two ocean-surf sounds.
