Evo - White Noise Machine and Non-Looping Fan Sounds with Sleep Timer (Black)

Button layout makes it very easy to use, even in a fully dark bedroom. Unit is not lit up, which is exactly what I wanted. Great sound quality, and good choice of different white noises or fan sounds. Good volume range too.has really helped my sleeping. I'm very sensitive to background noises, helps drown them out so they don't wake me up.

I have three of these, and will be getting another when funds allow. They have genuinely helped me deal with the most awful upstairs neighbours. (This is why I have three; when I had one, I was carrying it round with me! Now I have them dotted around strategically.) I am hearing impaired but can hear low frequencies - like the bass and thumping from upstairs. Drowning out bass is difficult, but there are a variety of sounds at different frequencies in this machine and the trick is to find one that matches the frequency you are trying to disguise. If, for example, you have someone living above you that plays music with amplified bass, and they also shriek, you may find two machines useful (one to match the bass, one to match the shrieking). I find the continuing hum of the machines very quickly settles into the background and is far easier to ignore than noise from upstairs. These machines are tiny (10cm, see picture) and they need to be plugged in. The cord on the white machine is white, with a USB at the end, but the supplied USB plugs in all of mine have been black. This is annoying at this price point, but the overall quality of the machine more than makes up for it.

The EVO is a small matte plastic box, the same shape as a 50p coin but about four inches on a side and sloping to the front, with a number of buttons on the top surrounded by a metal speaker grille. Its only other features are a 3.5mm headphone socket and a thin built-in cable, about four feet long, which leads to a USB-A female connector. A wall plug is provided but I can plug it into a USB-A port on my desktop PC and it is powered. There is no battery, no display, no LED, no Bluetooth and no smartphone support. The noise can be anything from barely audible to astonishingly loud, controlled by a pair of buttons. Another pair of buttons cycle between 10 whitish noises (brown through pink to white), 10 fan noises (anything from "industrial fan" through "exhaust fan" to "oscillating fan") and also ocean and surf effects. The quality of the noises/effects is excellent - there is no indication whatsoever of repetition or looping. Another button allows a timer to be set (one to eight hours); otherwise, the EVO runs continuously. The only other substantial options are a switch between continuous and oscillating noise level and a factory reset - both are done through combinations of buttons. Power consumption is tiny - according to my smart plug, 1 watt. The EVO concentrates on generating and playing noise and has no frills. In my situation it is stunningly effective - noisy upstairs neighbours are completely blocked out, far short of the highest volume setting. It can even fully block the noise of a big Coway air purifier running at its highest setting a few feet from me, which is astonishing. It is far superior to the smartphone/white noise app/Bluetooth speaker combination suggested by various sources, not least because it is zero maintenance. Four stars because £80 is expensive no matter the quality (I got my EVO for a discount, £65). However, it is a great example of a device that performs a well-defined task without fuss but has excellent design and hides a lot of sophistication behind a few buttons.

This is the best white noise machine I have ever had. It covers all the noise from the neigbours banging their outside doors, thunderstorms, fireworks. People can't hear me singing next door. Very good value! I am autistic and this is definitely a product that I highly recommend if you have noise sensitivity like I do. I have them on for sleeping in the night so traffic and loud engine cars or motorbikes don't wake me up.

- Last few years have been using a Muzo fan to try to mask various sounds that permeate my flat. - It, too some extent worked, though the volume was hard to get just right with its dial, which light up my bedroom with the most incredibly bright LED, which was a bit poor IMHO. - So I took the ‘plunge’ and bought the ‘lectrofan, though quite expensive it already has helped me through a period of the noisy Friday afternoon. - It was so easy to set the sound and volume, much better than the Muzo, plus no ultra bright LED. - I tested its loudness vs a Bluetooth speaker I use for music, an Anker (the small one). - The Anker can produce white house when it’s in radio mode and not able to tune in. - The ‘lectrofan was about the same output, really quite loud! - Which when you need it, it has that ability. - Getting used to the buttons to control its output was super easy as was figuring a sound for it to emit. - Very happy with it, would recommend if like me your neighbour is loud, the outside environment has a tendency to be loud, and on a Friday a loud pump goes off for an hour to sort our building’s fire extinguisher.

If you are like me and can't sleep in complete silence, this is so worth the money. It has good sound quality, it's small enough to easily travel with. I can't recommend it enough.

Really works. I didn't believe it would. I've loud neighbour's and when I've the machine on I dont hear them . I turn it off every so often to double check they are there....and they are so back on it goes :). It has saved my sanity.

I was a bit disappointed with this. There are lots of different sound tracks to play, and the volume range is good, but the quality of the tracks, or the ability of the speaker to render them isn't quite there. They sound flat, and sometimes I feel there is a bit of distortion which I find very distracting. I don't use as a result.

الصوت خفيف مو مثل اللي قبل

If you're living in the Netherlands, this is a lifesaver! I wish I would have known how good this is before, it'd have saved me from years of misery. It drowns the noise of screaming children outside in the daytime, so you can focus working and shouting drunkards in the night, so you can sleep. I do need to put the volume quite high to drown the noise of the children as they're VERY loud, but then the sounds are almost completely muted. I like the compact size and white color too. Maybe would be nice to have more nature sounds. Though the basic fan sounds seem to work the best for canceling out noises. Such great machine, might get a second one at some point.
