Sleepbox Sleep portable Sound machine
It’s small enough you can literally keep it anywhere, great to travel with and has lots of different sound options. My personal faves are the rain and ocean sounds! It also has a strap attached to hang it if needed. Doesn’t need batteries, it has a USB to charge it. Very pleased for the price of this! Highly recommend

Great little sounds machine
Wow, this thing works great! Lots of sounds to choose from and the sounds quality is great. The volume options are great. Can go quite to very loud. Love the small size and hanging rope. Was used for many nights before needing recharged.

Must buy, won’t regret.
Great little sound machine. Specially for the price. Good quality sound and battery. The only thing is missing is a feature that wouldRestart when baby starts crying but for the price it’s really more than enough everything it has. 100% recommend. Very portable too!

Clear sound for such a small device. Perfect!
Its a great little item. Sound is very clear. The reason for 5 stars is it needs a indicator light so I know if its fully charged.

It works and has good selection of sounds
It works, has good battery life, and time choices for automatic shutoff. Nice selection of sounds. A better choice for me than urng a phone app. I got this after seeing our Dr. use this brand both for privacy and calming effect.

Small but mighty!
Was a little shocked at how small this sound machine is. I was doubtful that it would have decent sound, but I am very happily surprised! Great sound, lots of good choices and wonderful size for traveling with me. 🙂

I love this little guy so much! I do a lot of travelling and I was falling asleep with the tv on because hotel rooms can feel lonely. But my sleeps were always restless. Now, no TV, no phone, just whatever peaceful sound I choose that night, and I sleep like a baby!
