This Zazu Suzy de Luxe rechargeable sound machine pairs a soft silicone strap with a sturdy ABS body for a portable, hangable sleep aid. This white noise device offers 14 soothing sounds — heartbeat, shushing, white/pink/brown noise, sea sounds, lounge tracks, and lullabies — plus a cry sensor that restarts the last used setting when a child starts crying. This model includes timer or continuous play, adjustable volume, and a rechargeable battery with over 100 hours runtime (USB charging cable included), making it perfect for travel and daytime calming. This portable baby soother helps create a secure sleep environment and supports calmer routines for both children and parents.
