Adaptive Sound Technologies Lectrofan Micro2 Sleep Sound Machine and Bluetooth Speaker with Fan Sounds, White Noise, and Ocean Sounds for Sleep and Sound Masking

Good product and functions as expected.

Bought Sept 2021, reviewed May 2022 I did a lot of research before buying this as I wanted something I could travel with, (so USB charged) and also a specific sound of white noise that I had found on an app and played through my phone. I saw a useful You Tube review by an independent reviewer and he very helpfully played the sounds of each product, so I knew that this would replicate that exactly, whereas many of the others didn’t. It also has a good choice of white noise sounds, which are more what I require, as opposed to sounds of water/nature or melodies. It's incredibly compact and feels nicely weighty and well made. It is the perfect size to chuck in a travel bag and takes up next to no room on a bedside desk. Just about the only thing that could be improved is the buttons which are small and I find I can't usually operate without turning the light on. This could of course be because of my sausage fingers! That said, other than sliding the on/off switch at night and again in the morning, I tend to leave the volume and sound settings the same, so it's not really an issue. The sound it chucks out is amazing for its size and the directional speaker does make a difference - I always use it with this deployed. The first few weeks I had it I wasn't at home and didn't have access to a suitably close power supply, so I ran it off the battery and charged it during the day. I found it went 3 - 4 nights on a full charge. I like it quite loud, so maybe that uses more power than a quieter volume? Once I was back home I plugged in the USB cable and have it attached to that and the power source all the time and it sits by my bed. There's a small green light on the back, but it has never disturbed me and it could be covered with a tiny bit of tape if it was an issue. I recall reading reviews where people said the USB connection port was prone to failure, so I decided to leave the cable in to reduce wear and tear. I've not had any issues. In terms of effectiveness I find that it really helps me sleep and stay asleep. I live in 5th floor flat in a busy area, with a main road junction and the associated police/fire/ambulance noise that always accompanies their approach to it, day or night. There are rail lines and frequent aircraft noise from the landing and take-off patterns at LHR and LCY. I also have a selection of neighbours who don't always appreciate that night time is not the right time for loud noise and their gardens host the nocturnal gatherings of foxes. Anyone who knows what foxes sound like at night knows that it isn't soothing. There’s a primary school a couple of streets away and when the kids are out at breaktime the noise feels like they’re in the house with me. On top of that there is a public car park very close, so associated noise with that and the Police helicopters fly past at low altitude multiple times day and night, en route to from their base. All in all a challenging environment. Add to that that I really like my bedroom window open most of the year to provide fresh air and that I regularly have strange working hours which require sleeping at all times of day and night. So this thing has its work cut out. It doesn't blot out everything, obviously, but I find that I have a quite high tolerance for noise, so having it on quite loud does do a remarkably good job as it is a consistent sound, rather than all the random sounds of the outside. I woke up one morning recently and on turning it off heard a conversation going on below my open window, which was accompanied by a car engine running and the sounds of the car radio - none of which I had been able to hear with the white noise on. I know it would probably have woken my up pre-alarm had I not been using the Lectrofan. The door buzzer to my block is pretty loud in the flat and always used to wake me up. I unfortunately missed a delivery recently as this thing blotted out enough of the jarring ‘beep beep’ that I slept through a courier who arrived only three hours after I’d hit the sack. Coupled with blackout curtains, the Lectrofan makes me fall asleep much easier than I would without that buffer layer of white noise to smooth out the rough edges of the noise outside. It is very rare that I wake up in the middle of the night now for anything other than the call of nature!

It’s good except it’s not that loud. I got the original lectrofan and it’s very much louder. That one have made me sleep thru things I wouldn’t have believed before I tried

la calidad es muy buena!! los sonidos son perfectos para usarlos por la noche con mis bebes.. lastima que ya no lo venden porque quisiera comprar otro igual

I started using a sound machine to mask a CPAP machine. I was hesitant of electronic devices due to repeats and such. But I’m going on a trip and wanted a smaller device to take with me. This one is very compact but works great. One of the fan options completely masks the CPAP sounds and I’m now sleeping better since not getting annoyed with the cpap noises. It’s more effective at masking than the mechanical machine I have. It lasts at least 2 full nights on 1 charge. I haven’t fully tested battery life yet. The way the speaker swivels up is slick as well. There are cheaper options but glad I went with this one.
