Tossing and turning at night? Can't fall asleep for that afternoon nap? Tune out the rest of the world -- and immerse yourself in the sounds of nature or still, white noise with our soothing White Noise USB Machine. Stress less and transport yourself to a different place with over 24 hours of sound-play time. All it takes is 1.5 hours of charging time to fully power up this white noise machine. Power up your device to relax during a stressful afternoon, lazy Sunday on the couch, or just to add some relaxing noise into the home during dinner prep time. Leaving the noise on throughout the night? Sleep with ease -- our machine has an automatic power-off timer you can set -- 15 minutes, 30 minutes, or 60 minutes. You can also just let the machine run throughout the night. A mini built-in LED breathing light illuminates along with your sound of choice for an ambient atmosphere. From meditation to a much-need massage. Completely USB-chargeable, our machine uses a built-in lithium battery that you can conveniently power up. The machine is compatible with any standard USB charging cord (one is included with your purchase) so you can plug into your laptop, portable battery pack, or wall outlet.
