pink noise machine

Many pink‑noise sound machines pair sound with lighting. Common features include adjustable night lights, color‑changing rings, multi‑color sleep‑trainer lights that cue toddlers, and dimmable warm amber or full‑spectrum color settings.

Some pink‑noise machines are designed for all ages, while others target infants and toddlers. Infant/toddler models often include sleep‑trainer features, nightlight options, and app‑based routines for baby sleep support.

Many units include a 3.5mm headphone jack for private listening; several function as Bluetooth or wireless speakers for streaming from a phone, and some offer app‑based controls to set favorites and schedules remotely.

Most machines list plastic or ABS plastic construction. A few descriptions note metal or stainless‑steel elements, and some models include a metal grille.
