Yogasleep Hushh Portable White Noise Machine

From the manufacturer

• EFFECTIVELY MASKS NOISE: Beloved by generations since 1962, Yogasleep by Marpac is the trusted leader in white noise machines, and created our signature sound – the soothing ambient sounds of rushing air. That sound that’s helped millions experience better sleep for generations is now available in this light and portable design for babies. The Hushh effectively cancels out noises that may disturb or distract for improved sleep and soothing.
• 3 SOOTHING SOUNDS & NIGHT LIGHT: Choose from bright white noise, deep white noise, or gentle surf, then set your volume - anywhere from whisper-quiet to impressively robust. Hushh lets you take control of the sound environment, excellently masking background noise and allowing for better sleep and effective soothing for kids and babies. A gentle amber LED Night light provides just enough light to see by without causing wakefulness for parent or baby.
• COMPACT & PORTABLE: At just 3.5" in diameter and 3.8 ounces, Hushh fits easily in a diaper bag or backpack and comes with a baby-safe clip for easy fastening to a stroller, car seat, or crib.
• SIMPLE TO USE & CHILD SAFE: Forget batteries and electrical outlets - Hushh can operate 6+ hours on a single charge, and comes with convenient USB cable for recharging. The simple interface is easy to use and operate with one hand and Hushh offers the ability to lock at a desired setting and volume to prevent younger hands from altering the sound or turning the unit off.
