- Reviewed in the United States on May 17, 2025Color: WhiteStyle: EVOVerified PurchaseI purchased this item in May of 2024 and since it's been so good it is about time I write a review. I have tinnitus as a result of 20 years of structural steel erection in my younger days, and hear birds chirping 24/7. This since the mid 1980s. I tune it out most of the time but when you lie down to go to sleep in total silence the chirping is front and center. Using the pink noise setting allows me to focus on the sound generated by the machine instead of the tinnitus. My upstairs neighbor is generally quiet but if there's a piece of furniture moved, scraping on the tile floor, it is sort of part of the surrounding sounds. If the machine wasn't on it would break the total silence and be very disturbing. So I'm very happy with this acquisition and it has definitely been worth the price.
- Reviewed in the United States on April 13, 2025Color: WhiteStyle: EVOVerified PurchaseThe LectroFan Evo is by far the best sound/noise sleep aid machine I've seen or used! The sound is very rich and deep and includes some lower-frequency noise settings that can mask even things like trash trucks or leaf blowers outside if I turn the volume up loud enough. And it does get quite loud, thanks to the high-quality speaker and enclosure. I prefer the noise/static sounds but there are good fan-like sounds if you prefer that. It's powered by a plug-in USB adapter, so you can power it from a USB power cell if needed. There are no LEDs/lights to potentially interfere with your sleep, and the button layout is easy to learn and navigate without looking, if you need to adjust the volume or change sounds or set the timer in the dark. It remembers your settings even if you unplug it for a while, and there are a couple customizable options like auto-power-on/off. I've found no downsides with this sound machine, and it's well worth the cost for helping me get a good night's sleep no matter what annoying noises are going on outside!
- Reviewed in the United States on May 29, 2025Color: WhiteStyle: EVOVerified PurchaseThe only product I’ve ever reviewed on Amazon. I love the simplicity of this machine along with the uninterrupted sound. It’s perfect for the baby’s room. Thank you!
- Reviewed in the United States on January 19, 2025Color: WhiteStyle: EVOVerified Purchaselimited # sounds, some screechy. But drowns out other surrounding nuisances
- Reviewed in the United States on May 17, 2025Color: WhiteStyle: EVOVerified PurchaseWow wow wow! I purchased this product because of a heavy walking upstairs neighbor in my apartment… It muffles the noise so I am happy… What I’m really happy about unexpectedly is that I am sleeping so much better! This was a pleasant bonus!
Worth every penny!!
- Reviewed in the United States on April 29, 2025Color: WhiteStyle: EVOVerified PurchaseThis sound conditioner is fine. I have been very satisfied using it. Perfect for apartment/ condo use to mask unwanted noise. It has many different settings and I use the one that sounds like a fan whirring. The volume adjusts with a click of a button. Small compact size is good on a nightstand or bookcase. These make good gifts for sleeping or studying. Only uses about 4 or 5 watts. Used this one for about a year now and it's fine so far.
- Reviewed in the United States on April 7, 2025Color: WhiteStyle: EVOVerified PurchaseI'm most impressed with the volume control on this first of all! Very precise small incremental changes so you can keep it medium-quiet but also amp it up if you need to when your cats are begging for breakfast too early. 22 different sound options total I believe, 10 fan and 10 white noise and 2 "ocean" although the ocean sounded more like further white noise options to me. No ability to combine sounds, if that's what you're looking for. For anyone like me who just likes to pick from multiple good white noise or fan settings though, this is perfect.
- Reviewed in the United States on March 13, 2024Color: WhiteStyle: EVOVerified PurchaseFor over a decade my wife and I have put on the sound of ocean waves on our beloved Squeezebox radio devices as white noise to fall asleep to. We had a pug that would snore pretty loud, so needed something to drown that out -- and besides that, when it's dead silent and the house is creaking or there's some other noise to fixate on, it can sometimes be hard to fall asleep. So the Squeezebox device worked well, except several times a year or more there were either power glitches or network glitches that caused the white noise to be interrupted -- which would inevitably wake us up and have one of us walking over half-asleep to reset the radio, sometimes cursing at it because it wouldn't just reset. I eventually decided that it'd be nice to have something that just did white noise and didn't require any network connection -- or would restart itself if the power went off.
I now have 4x LectroFan white noise machines. Two of this model and two of their more basic model. They all work well. I have one in the guest room for when guests are over, we were using one by our puppy's crate for a number of months, there's this model in our bedroom for falling asleep to ocean waves and then a sister to that one that is only for traveling.
My wife thought I was nuts for buying the first one. Probably because of the fact you can play white noise on your phone, we had the Squeezeboxes playing ocean waves, etc. But then after we used it for a while, she started to love it -- and also love the simplicity of them. You just hit a button. It remembers the volume and whatever tone you had previously set. If the power goes out, it comes right back on with the same tone and volume. And it just works! No fussing with loading an app, with a phone heating up or battery dying during the night, or network issues to interrupt the streaming of the white noise.
So all-in-all, very happy to have purchased this and wouldn't hesitate to recommend. There is no looping. It can get pretty loud. And it just works!
With these having an advertised power rating, I felt really comfortable buying it. I think it's under 3w or something like that -- and that's how it should be. Yes there are cheaper options, but do they have a noticeable loop in the sound? Do they consume very little power? Are they good build quality? Are they going to heat up or burn up or worse? I'd rather pay a bit more knowing I'm getting a quality product these days, especially if it's plugged in 24/7.
This is a buy-it-once type of device that should last for years and years judging by other people's experience, so well worth the cost for something you'll use almost every single day IMO. Definitely recommended!

Color: WhiteStyle: EVOVerified PurchaseVery pleased with the Adaptive Sound Technologies LectroFan Evo. The brown noise works very well for covering the sounds from a busy street. It is very easy to use. Once you select the sound and volume that works for you, all you need to do is turn it on. Your previous selection remains.

5.0 out of 5 stars Difficile de s'en passer
Color: WhiteStyle: EVOVerified PurchaseAprès presque 2 mois d'utilisation, difficile de s'en passer. Je pensais que ce serait gadget mais au final, après le deuil du silence et la difficulté de dormir avec des acouphènes, j'ai voulu investir dans une machine à bruit blanc. J'avais regardé une review et je me suis dis, pourquoi pas. Bien qu'un poil onéreux par rapport à d'autres produits concurrents, la qualité des enceintes avait eu raison de me convaincre.
En bref, je l'allume toutes les nuits et ça me permet de passer outre ce signal sonore auditif qui rend fou. Il y a une fonctionnalité de minuterie par heure vraiment pas mal et qui s'enchaîne à l'infini (il y a un retour d'un petit bruit qui signifie que c'est pris en compte). Mais si comme moi vous vous réveillez pendant la nuit, c'est mieux de laisser tourner jusqu'au réveil. J'espère juste que cela ne l'usera pas plus vite que si j'utilisais la fonction d'éteinte automatique.
Je trouve honnêtement le design pas super mais bon, c'est une boîte à poser à côté de soi, c'est pas un objet à regarder donc ce n'est pas un critère essentiel.
Il y a pas mal de pistes sons possibles donc tout le monde peut y trouver son bonheur et le son est vraiment top, ça peut aller très très fort et la machine est assez petite pour être transporté assez facilement pour voyager.
Je recommande fortement :)

5.0 out of 5 stars Allows me to sleep, even if my downstairs neighbours are having a party on a weekday
Color: WhiteStyle: EVOVerified PurchaseI wasn't sure if the amount I was spending on this product would be worth it, but I have to admit I was wrong.
This has been a real gamechanger for my sleep, a while ago I received a new downstairs neighbour who is incredibly loud at night, parties on weekdays and such. I used to run a fan to have something to filter out the noise, but sometimes not even that would deal with it all.
This thing however has managed to help me a ton, I am able to sleep far more easily now.

5.0 out of 5 stars Wish I had gotten it sooner
Color: WhiteStyle: EVOVerified PurchaseI've been using a white noise ap on my phone and ipad for the last 10 years but this device here has brought an end to that. Yes, it costs more... but what price can you put on a good night's rest? The stomping from neighbors upstairs is entirely mased by the deep brown noise at full volume.
Be sure to read the guide to understand how the device works, there are more options than yo umight realise at first.
