DREAMEGG SLEEP LITE D11 This product plays white noise sounds. It's convenient to have one because you can't use your smartphone while playing sounds from YouTube. The sound comes from a speaker, so the sound quality is relatively clear. I'm selling it because I no longer have the opportunity to use it. - Please understand that the box may be crushed or have storage-related stains. - Everything in the photos is included. - Please purchase only if you understand that this is a used item. - Model Name: DREAMEGG SLEEP LITE D11 - Function: Portable Sound Machine - Design: Circular Design - Accessories: Power Adapter Thank you for looking.
