The Best White Noise Machines In 2021

photo of the lectrofan evo and sound+sleep white noise machines

Using a white noise machine is an effective way to mask external noise that’s disturbing your sleep, work, or studies.

They aren’t always so effective if you have loud impact noise from an upstairs neighbour stomping around on wooden floorboards. But they can help block out a lot of airborne noise, such as music or television in other rooms, cars passing, people talking, and dogs barking in the distance.

In this review, I’ll be discussing eight white noise machines. In each section, you’ll find a video review in which I demonstrate the main features and play through all the sounds so you can have a listen yourself.

If you don’t have time to watch the videos though, I’ve included written summaries to help you scan for the information you need.

Please note that I’ve been doing white noise machine reviews for many years, so you’ll notice different styles depending on exactly when I filmed them.

5 tips for buying a white noise machine

Sound options. There are two main categories: machines that contain a real fan, and those with recordings or the digital generation of sounds. In this review, only the Snooz and Dohm Uno have real fans, and neither of them has other sound options. Some devices have an even balance of white noise, fan sounds, and nature sounds. Others focus more on white noise, or have mostly nature sounds. So keep an eye out for one that offers what you’re looking for.

How it’s powered. Most devices need to be plugged in to work, and come with a standard adaptor plug, a USB cable, or both. The Dreamegg and LectroFan Micro 2 have an internal rechargeable battery so you can place them where you like. The Big Red Rooster can be powered by AA batteries, which also allows for flexible placement.

Auto-off timers. Many devices have auto-off timers or the option to run continuously. They don’t all have the same timer lengths, so make sure you choose one with the length of time you think you’ll need.

Dimensions. White noise machines tend to be relatively small and easy to transport. However, some are larger than others and can take up a fair bit of space in a suitcase. So make sure you choose a small one if you need to travel with it frequently. Alternatively, a white noise app on a smartphone might be a good enough option when traveling.

Price. The cheapest in this comparison is under $20 and the most expensive just over $100. Unless you really need the more uncommon features that the expensive ones have, you can get a very good device in the $30-$60 range.

Lectrofan video

In the video below, I discuss the features and play all the sounds of the LectroFan Evo:

The most important job of a white noise machine is to block out external noise by replacing it with a sound that’s more relaxing and constant. So it helps to have different sounds to choose from so you can find one that works well and that you can listen to for extended periods of time.

It’s also useful to have a good range of volume so you can block out louder noise if you need to, but turn it down when it’s quieter outside. The LectroFan Evo has a good range of sounds (22 in total) and incremental volume controls, so there’s a lot of flexibility to find the right combination of sound and volume for your particular setting.

It has a wide range of white noise and fan sounds, ranging from standard bedroom fan sounds to a hairdryer and industrial fans. And I like how it doesn’t just have intense white noise, but deeper colors like pink and brown noise too, which some people find more relaxing. Think powerful waterfall and TV static, and you can imagine the two ends of the spectrum it offers.

The speaker quality is very good for a white noise machine, and the maximum volume is the loudest of the models in this review. So it’s capable of blocking out louder noise that might be coming from outside your bedroom, such as music and cars passing by.

On quieter nights, you can turn the volume right down to give your ears a break. The white noise itself is dynamically generated rather than using recordings, which results in a non-repeating and constant sound.

It also has two of the most important extra features I look out for: a headphone jack for private listening, and auto-off timers if you don’t need your white noise on all night.

I also like the minimalist design and the fact that it’s relatively small, so it’s easy to transport. It’s a shame that it doesn’t have an internal rechargeable battery, but the option to power it either with the included power adaptor or USB cable gives some flexibility.

The main downside is that if you’re looking for lots of different nature sounds, the LectroFan Evo only has two ocean surf sounds. Neither of them has birds or thunder, and they kind of sound like more white noise to me rather than the ocean.

Overall, if you’d like a white noise machine for your home or office that has a decent variety of white noise and fan sounds, the LectroFan Evo is a good choice. It’s in the middle in terms of price – not a budget device, but it’s not as expensive as the Snooz or Sound+Sleep either (coming up).

Snooz video

In the video below, I unbox, play the sound, and review the Snooz. It’s a long video, as there are a lot of features to discuss!

The Snooz is the first of two white noise machines I’ll be looking at that have a real fan inside them. What I like about this style is that the sound is authentic. No matter how realistic the fan recordings are in some devices, you can tell the difference when you listen to one that actually has a fan inside the casing.

One of the common criticisms of other machines that have internal fans is their typically low volume. The Dohm DS, for example, only has two fan speeds and both of them are quiet compared to the Snooz.

The Snooz has 10 volume settings, based on the fan speed, and the maximum volume is the loudest of any I’ve tested that use a real fan. In fact, it’s louder than many standard white noise machines with a speaker and recordings.

You can also adjust the tone of the sound by rotating the side cap, which changes how the air flows through the case. There’s a nightlight of sorts on the buttons, which gives just enough light to see where things are in the bedroom. It’s not a particularly warm glow, but it’s a useful feature nonetheless.

Both a pro and a con is the accompanying smartphone app. It’s a con in that some features can only be accessed with the app, like the timers. That’s not exactly universally user-friendly. But for those who do have a smartphone, I like how you can set multiple timers per day of the week, with a fade in and fade out option that I’ve not seen on any other device.

It’s also convenient that you can turn it off without getting out of bed if you’ve placed it out of arm’s reach on a table, shelf or windowsill to mask external noise.

The Snooz looks great aesthetically, which helps offset the fact that it’s one of the more expensive white noise machines out there. Even so, it might not be the right choice if you’re on a tight budget as you can get reasonable white noise machines for less than half the price of this one.

On balance, if you enjoy listening to fan sounds, and have been frustrated by the lack of sound blocking because of the low volume of other mechanical fan style white noise machines, the Snooz is a good choice.


3. Avantek

A good option if you like nature sounds and white noise

AVANTEK WHITE NOISE MACHINE

Specs & features

  • 20 Sounds: 6 white noise, 6 fan sounds, 8 nature
  • Headphone jack: no
  • Auto-off timers: 1 – 9 hours, or continuous
  • Power: standard adaptor or USB (both included)

  • Length: 3.9″
  • Width: 3.9″

Avantek video

This is one of my earlier videos, when I was still a bit camera shy! There’s no talking, and all I do is play through the sounds. Still, for the purpose of this comparison article, it’s a good one to get an idea of the exact sounds it offers.

The Avantek is the first of several I’ll look at that combine white noise, fan sounds and nature sounds. It’s a good one if you’re not sure what kind of white noise might work for you, or if you know you like to switch between standard white noise or more natural sounds like rain.

It’s not the jazziest looking device, but I like the simplicity and the fact that it’s very easy to use. There are simple buttons for the volume, sound choice, timers and power. And you can power it either with the included power adaptor or just the USB cable and any USB outlet in your home.

The speaker quality is surprisingly good for such a simple-looking machine, with decent volume that will help block out other noise. The nature sounds are on reasonable length loops that aren’t obvious unless you really try to spot them.

It’s good that there are various white noise and fan sound options, ranging from deeper to more intense. So you should find one or two you like and that help mask external noise while you sleep or work.

There are seven timer options, which is more than most have. And tiny LED lights tell you how long the timer is, which is a useful feature that too many devices seem to omit.

The price is reasonable considering how many sounds it offers. You can usually pick it up for under $40, which is half the price of the most expensive brands, and not much more than reasonable budget devices.

So all in all, I think the Avantek is a good all-rounder. It might not have as many features as some of the most flashy machines, but it gets the basics right while being very user-friendly.


4. Sound+Sleep Special Edition

If you’d like a wide range of sounds and extra features

sound+sleep special edition

Specs & features

  • 64 sounds: 44 nature and ambient, 12 white noise, 8 fans
  • Headphone jack: yes, 3.5mm
  • Auto-off timers: 30, 60, 90 or 120 minutes, or continuous
  • 2 x USB charging ports
  • Responsive volume adapts to the ambient noise level
  • Audio-in cable included to play your own music
  • Power: standard adaptor (included)

Dimensions

  • Length: 7.5″
  • Width: 5.5″
  • Height: 4.5″
  • Weight: 2.6 pounds (1.18 kilograms)

Maximum $105

Sound+Sleep video

In this one, I play through the main 16 sound categories. I also demonstrate some of the features unique to this device, such as the way the adaptive sound responds to changes in the ambient noise levels.

The Sound+Sleep Special Edition is an outlier compared to the minimalist design most white noise machines have, with an extensive set of sounds and lots of additional features you’ll rarely find on sound machines. That creates extra weight though, and it’s the heaviest and least portable device in this comparison.

It has 16 main categories on the central dial, and a selection button to choose between four variations. That makes 64 different sounds to choose from.

Some settings just add extra detail, for example adding thunder to the rain. Others are very different, such as a train ride or boat ride. I like how you can decide to have birds with the brook, wind with rain, or just keep it simple. And like the LectroFan Evo, it also includes a good range of white, pink and brown noise, as well as a choice of soft fans or more industrial styles.

One feature that’s unique to this device is responsive volume. If you select that, it will automatically change the volume according to the ambient noise levels in the room. It’s a feature not everyone will want to use, but it does work well.

It has a useful headphone jack, auto-off timers, and two USB charging ports for your smartphone or other devices. There’s an audio-in cable, so you can play your own sounds or music through the speaker. The speaker itself produces clear sound, and I found it’s capable of masking noise coming from outside the room.

The main downside is that it needs to be plugged in at all times using the included power adaptor. It’s also larger than most other devices I’ve tested, so it’s one to keep in the bedroom or office rather than travel with. The Sound+Sleep devices (there are a few versions) are also one of the most expensive white noise machines out there, so it’s not a budget option.

With so many sounds and features though, this is a versatile device and one for people who love nature sounds, and who prefer their tech to be rich in features.


5. Yogasleep Dohm Uno

For those who like a device with an internal fan on a budget

marpac uno

Specs & features

  • Sounds: rushing air from an internal fan
  • Headphone jack: no
  • Auto-off timers: no
  • Power: hardwired standard plug

Dimensions

  • Length: 6″
  • Width: 6″
  • Height: 4″
  • Weight: 1.6 Pounds (726 grams)

Dohm Uno video

In this video, I compare the Dohm Uno with another model. The smaller one isn’t included in this written article, but you can see the Dohm Uno in action as I demonstrate how the tone of the air changes as you turn the cap.

The Dohm Uno is a newer version of the classic Marpac Dohm – the first white noise machine to use an internal mechanical fan. Marpac merged with the company YogaSleep, so the old Marpac Uno is now called the Dohm Uno.

The Dohm Uno is very easy to operate, with just one button. That button starts up the internal fan and pushes air out of small holes around the casing. The only option you have to change the sound is to twist the cap, which slightly changes the tone of the rushing air sound as it flows through the holes.

And that really is it – there’s nothing else to do with the Dohm Uno. It does a simple job, and it does it pretty well as the resulting sound is authentic and relaxing to listen to. As with the Snooz, the use of a real fan sets it apart from the devices that only use recordings of fans.

My main criticism is that the sound produced is relatively quiet compared to the other sound machines, and much quieter than the Snooz. So if you need it to mask external sound, it will struggle to block out loud noise coming from other rooms or outside.

And if you’re looking for additional features like a headphone jack, internal battery, or auto-off timers, you won’t find that with the Uno. It just doesn’t have any features at all.

Despite the lack of volume and extra features, if you like the idea of having the authentic sound of air made by a real fan, the Dohm Uno is a good choice for a reasonable price.


6. LectroFan Micro 2

If you’d like the smallest possible device and an extra Bluetooth audio option

Specs & features

  • 11 sounds: 4 white, pink and brown noise, 5 fans sounds, 2 ocean surf

LectroFan Micro 2 video

In the next video, I explain why I like this one for travel. I also play through all the white noise and fan sounds, and demonstrate the Bluetooth speaker with some music played from my phone.

The LectroFan Micro 2 is my personal favorite for travel or for outside use. It has an internal rechargeable battery (charged with the included USB cable) that lasts for more than one night on a single charge: 20 hours with white noise, and 40 hours on the Bluetooth setting.

Like the LectroFan Evo, there’s a good variety of white noise, ranging from relaxing brown noise to more intense white noise. There are enough fan sounds to cater to different tastes, and two ocean surf sounds. Like the Evo, the ocean sounds don’t have birds or thunder, but they are quite pleasant to listen to.

I like that it can be used as a Bluetooth speaker, so you can play your own music or different nature sounds if you prefer. This isn’t a common feature for white noise machines, and it offers flexibility for when you’ve had enough of the same white noise on repeat. It doesn’t have much bass though, so you’re unlikely to be dancing around it.

Despite the lack of bass, the speaker is louder than I expected for such a small device, and I found it was capable of masking a lot of ambient noise coming from other rooms and outside. I also like that you can swivel the speaker, so you can point it upwards to fill the room with sound or to the side if you prefer.

The main downside is that there isn’t an auto-off timer. I think this is a basic feature for a white noise machine, so I was surprised to see it omitted. Another potential issue is the tiny buttons. If you have finger sensitivity issues, or need to operate it in the dark, you might find it frustrating to use.

Overall, the LectroFan Micro 2 is a convenient white noise machine for travel because of its small size, Bluetooth speaker option, and internal rechargeable battery.

7. Dreamegg D3

A good option if you’re playing white noise to kids

Specs & features

  • 24 sounds: 7 white, pink and brown noise, 7 fans, 9 nature sounds, 1 lullaby
  • Headphone jack: yes, 3.5mm

  • Power: USB cable (included)

Dreamegg D3 video

In this video, I play the sounds of the Dreamegg, and show the features in action, along with the internal battery.

The Dreamegg D3 is a good mid-range white noise machine that was designed with the parents of young children in mind.

In addition to the eight relaxing nature sounds, there’s also a soothing lullaby and a hypnotic heartbeat sound. But if that doesn’t quite work, there’s enough white noise and fan sounds to try out too.

The internal rechargeable battery also makes it useful for parents, as you can place it wherever you like in a room without needing to think about the power source. And the auto-off timers help prevent it from running for longer than really necessary.

Conveniently, the white noise, fan sounds, and nature recordings have been split into three category buttons. That means it’s quicker to cycle through them to find the exact sound you want. It might seem like a trivial point, but it’s better than cycling through all the sounds by pressing the same button repeatedly.

If you’re going to use it yourself, there’s a standard 3.5mm headphone jack for personal listening. Using it that way can also potentially block out more external noise, especially if you have good headphones.

My main criticism is that some of the nature sounds are on short loops. That’s a common issue with the nature recordings on sound machines, although it’s not so noticeable with some sounds that are more repetitive. For example, you don’t notice the loop with the brook sound as much as you do with the thunder.

Overall, the Dreamegg D3 is a good choice for parents, but also for people looking for a good all-around device for their own use. It has a good balance of features and sounds, and for a reasonable price that will suit lower budgets.

8. Big Red Rooster

Choice of standard batteries or a USB cable

Big Red Rooster video

In the final video, I play all six sounds of the Big Red Rooster, and talk through the features.

The Big Red Rooster is the only white noise machine in my current selection that can be used with normal batteries. It takes 3 x AA, which aren’t included. It does come with a standard power adaptor though, so batteries aren’t the only power option.

It only has six sounds, which is much less than the other non-fan devices I’ve discussed above. On the plus side, it’s very easy to use the Rooster as each sound has a labelled button so you can quickly select them. Those buttons are a little clicky though, which lets the device down in terms of overall feel and quality.

The nature recordings, as is so often the case, are on short loops, but they do sound reasonably good. The thunder needs to be kept at a lower volume though, or it tends to distort while rattling the casing.

There are auto-off timers, which is useful. But there’s no headphone jack or other additional features. The speaker quality is okay for a budget device, just nothing to get too excited about.

Overall, I think this is one for people who really don’t want to spend much on a white noise machine and appreciate the extra portability that comes from having the option to use normal batteries.

But if you’re looking for high-quality sound, I’d perhaps stretch the budget a bit further. For around $20 you get a low-cost device like this, while for $30-$50, the quality increases significantly.
