From Marpac, makers of the beloved Dohm-DS All-Natural White Noise Sound Machine, comes Hushh, a portable electronic sound machine designed to help baby fall asleep and stay asleep anywhere. The Hushh cradles your baby in soothing sound to create a comforting, consistent sound environment for sleep. This compact portable unit comes with 3 sound options: choose from bright white noise, deep white noise, or gentle surf and a wide volume range. Hushh is powered by a lithium ion battery and recharges from a micro-usb cord (included). Throughout nighttime or naptime, it masks disruptive noises to promote longer, more restful sleep cycles.
