Since Adaptive Sound Technologies, Inc. took the Lectrofan Micro2 Sleep Sound Machine into their fold, they have busy improving the already popular designs. With the Lectrofan Micro2 Sleep Sound Machine, their engineers once again have done an admirable job taking on board criticisms of the original version and making it even better. Just to be clear, the original was already an effective white noise machine.

The Lectrofan Micro2 Sleep Sound Machine designs

The Lectrofan Micro2 Sleep Sound Machine is tiny it literally fits in the palm of your hand, weighing just 6.4 ounces or 180grams and measuring 2x2x2.1 inches, it is ideal for travel and only consumes a little space on your nightstand.

The internal battery also makes it convenient if you are on the go, as you can use it outdoors and place it anywhere you like in a room rather than having to plug it in.

The Lectrofan Micro2 Sleep Sound Machine features

Many portable white noise machines are not as short on sound options as they are in stature. The Lectrofan Micro2 Sleep Sound Machine has a choice of 11 sounds, which is great as not everyone will find the same fan or white noise appealing. There are deeper sound options for those who do not like white noise, but you might want to try out the bright white noise. It also helps with sound blocking, as some noises are better at blocking unwanted external noise than others.

Here is the list of sounds you can choose from the Lectrofan Micro2 Sleep Sound Machine

White Noise 1, white noise 2, white noise 3, white noise 4, fan 1, fan 2, fan 3, fan 4, fan 5, Ocean 1, and Ocean 2

Strangely enough, you will not find any information about the speaker wattage, either in the instructions or on the AST website. However, once you turn it on you will notice it is louder than other portable devices, even some larger sound machines.

But more importantly, it sounds crisp even at maximum volume. There is no distortion on the internal sounds at all. Having said that, when you use the Bluetooth speaker, some sounds, like piano, are better played on a mid-range volume.

And if you should want to listen to it quietly, there are incremental volume changes that still provide clear sound on low volumes.

The Lectrofan Micro2 Sleep Sound Machine battery performance

The Lectrofan Micro2 Sleep Sound Machine includes a USB charging cable that you can leave plugged in if you choose. But one of the Lectrofan Micro2 Sleep Sound Machine best features is the impressively long-lasting internal rechargeable lithium battery. It will go for up to 40 hours with a white noise sound, and 20 if you use the Bluetooth speaker. This is remarkable for a sound machine, and the longest battery life so far we have seen on portable white noise machines.

The Lectrofan Micro2 Sleep Sound Machine Bluetooth feature

As mentioned above, with the flick of a switch and a quick pairing, you can play music from your smartphone, tablet, or other Bluetooth devices.

It is great to be able to play different relaxing music at night if you want a change from the white noise sometimes. And you can add your own music during the day and fan sounds at night if you prefer.

You can also answer phone calls as there is a built-in mic that works really well.

The Lectrofan Micro2 Sleep Sound Machine verdict

A small portable device like the Lectrofan Micro2 Sleep Sound Machine will obviously have buttons that match its size. So while they don’t look disproportionately small, people with finger sensitivity issues might prefer a device with bigger buttons.

There is no timer options available on this device, which received a lot of criticisms from users. Other than these 2 disadvantages we found by testing the Lectrofan Micro2 Sleep Sound Machine, it is a very nice little sound machine that ticks the boxes in terms of practicality and sound quality.
