  • “Top Rec for New Parents”

    If someone were to ask me what things they absolutely NEED for a new baby I would recommend this first every time. I've been using it for over two years. I work from home and have dogs and a modest size house and it really helps my kid stay asleep while life noise continues. It was also nice to use when he was a young baby and we took him to baseball games and restaurants etc after his bedtime. Get one. Get two. - Jessica N. ★★★★★

Hear From Real Customer Like You

  • Great white noise device for babies, children and adults, LOVE IT.

    This noise machine has been great for my baby. We mostly listen to white noise, but the other options are really nice too. It's small enough that you can take it anywhere. We keep it on all night long, and the battery typically lasts a week. I love that it's rechargeable so I don't have to worry about small batteries with the baby. - Alexandria M

  • A must have for newborns

    The last noise machine I bought had to be plugged in to work. I ended up returning that one and purchase this one and I'm so glad that I did. Not only does this last for the entire night on a charge it has so many more options. You can play white noise, lullaby's, or nature sounds. It has multiple different volume levels and a timer. By the bed on a stroller, whatever. Absolutely worth the purchase - Rachel Z

  • We love this thing!

    This thing is absolutely perfect! It's so easy carry around the house, I love looping it through my baby wrap when I'm trying to get things done while wearing baby. It lasts 10+ hours and has great options. Would buy again and again! - Catherine B

  • Great sound machine

    I received this item a few days ago and so far so good! I got it for our puppy for the car, stroller for walks (we have a few more weeks until he’s fully vaccinated) and when he’s needing a nap in his play yard and having a hard time settling. This portable sound machine has been easy to use and I love that I can take it anywhere. At night we also have another bigger sound machine that is not very portable and it has been amazing for crate training since he sleeps in another room. Our little guy sleeps all night long so I’d highly recommend a white noise machine for puppies it helps a lot!

  • Hands down amazing

    I just got this in today, my aunt has a sound machine from this company that she uses for her daycare she uses this one specific lullaby that always works on my babies. I made sure this one has it and sure enough it did. Plus to get it on sale for $49 is amazing especially for the quality it is. I was unable to get my breastfed baby to stay down for a nap, no contact, until I started using this. I love the size and that the buttons are on the front having added in the ability to lock the settings is a bonus to the design.

  • LIFE SAVER!

    This little sound machine has become this mama’s favorite baby item. We own TWO just so we can keep one at our son’s daycare (because they said it works wonders for his nap time). We take it everywhere we go, we use it every night. There’s so many sounds to choose from so you can change things up and find what works for your baby. We love the white noise and the music box lullaby the most! I love that there’s a lock so if your baby gets ahold of it, he can’t change the sounds, volume or turn it off. It’s amazing! It’s worked out great for us, just clip it to his car seat or beside his bassinet. I would definitely gift this to every expecting mama I know, and I can’t shut up about it. If you’re hesitating, let this be your sign to go for it. It’s so affordable for such an awesome machine with GREAT battery life. You won’t regret it!

Faqs

Holomas Halo Sleep Q&A

Will white noise make my baby dependent on it to sleep?

White noise doesn’t create dependency - it creates consistency. Many parents use it to block sudden noises and signal sleep time, helping babies settle more easily. It can be used as part of a routine and adjusted over time as your baby grows.

Is the sound too loud or harsh for babies?

No. The machine is designed with soothing, gentle sound options that parents describe as calming rather than harsh or static-like. Volume can be adjusted to a comfortable level suitable for babies, helping them relax without overstimulation.

Is the night light too bright for sleep?

The night light is soft and adjustable, providing just enough glow for nighttime feedings or diaper changes. Parents appreciate that it doesn’t wake their baby fully or disrupt sleep the way overhead or lamp lighting can.

Does it actually help babies sleep longer, or just fall asleep?

Many parents report that their babies not only fall asleep more easily but also sleep longer during naps and at night. Continuous sound helps reduce sleep disruptions caused by sudden background noise, supporting more sustained sleep.

Can I use this while traveling or in different rooms?

Yes. The compact, lightweight design and USB charging make it easy to move from room to room or take on trips. Parents often use it to recreate a familiar sleep environment wherever their baby sleeps.

Do you offer international shipping?

Yes, we offer international shipping to many countries. Please refer to our Shipping Policy on our website for detailed information about shipping rates and delivery times.

What is your return policy?

We offer a 30-day return policy for unused and unopened products. If you are not satisfied with your purchase, please contact our customer service team to initiate a return. Detailed return instructions are available on our Returns & Exchanges page.
