LectroFan Micro 2 Review

Summary

The LectroFan Micro 2 is the best portable white noise machine I’ve used. The compact design makes it excellent for travel, and the speaker is good enough to mask external noise so you can relax at night.

It has a convenient rechargeable internal battery that lasts for up to 40 hours. With 11 internal sounds and the ability to use it as a Bluetooth speaker to play your own music, it’s a versatile device that ticks most boxes apart from the lack of an auto-off timer.

The good points

  • Good variety: 5 fan, 4 white noise, and 2 ocean sounds.
  • Small and lightweight design that’s ideal for travel or home use.
  • Doubles as a Bluetooth speaker.
  • Excellent sound quality and maximum volume.
  • The internal rechargeable battery lasts for 40 hours with white noise and 20 hours with Bluetooth.

Main criticisms

  • The buttons are quite small.
  • It doesn’t have an auto-off timer.

Improving the already good LectroFan Micro

Since Adaptive Sound Technologies, Inc. took LectroFan into their fold, they’ve been busy improving the already popular designs. I recently reviewed the LectroFan Evo, for example, which had several welcome changes.

And with the LectroFan Micro 2, their engineers have once again done an admirable job of 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. But I like that they’ve added separate buttons for the sound choice and volume control (it bugs me when they share the same buttons and you either tap or long hold depending on what you want to do). The USB charging cable is longer now, there’s an extra ocean sound.

Let’s take a closer look at why I like this little sound machine so much.


The good points


1. Portable and compact design

The LectroFan 2 is tiny – it literally fits in the palm of my hand. Weighing just 6.4 ounces (180 grams) and measuring 2 x 2 x 2.1 inches, it’s ideal for travel – or if you don’t want a large device on your nightstand.

The internal battery (see below) also makes it convenient if you’re 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.

2. Good variety of white noise and fan sounds

Many portable white noise machines are as short on sound options as they are in stature. The Marpac Rohm, for example, has just 3 sounds.

The Lecrofan Micro 2 has a choice of 11 sounds, which is great as not everyone will find the same fan or white noise sound appealing. Personally, I like the deeper sounding options, but you might prefer bright white noise. It also helps with sound blocking, as some noises are better at blocking unwanted external sounds than others.

I like that it has two ocean sounds as well. Even though they are digitally created, they sound authentic and are non-looping.

It’s also worth noting that the LectroFan Micro 2 creates the white noise sounds digitally. They are not recordings, so the sound is authentic and doesn’t loop.

List of the sounds

Note that the manufacturer says there’s a mix of brown, pink and white noise, but don’t specify which one is which. So I list them somewhat ambiguously as follows:

  1. White noise 1
  2. White noise 2
  3. White noise 3
  4. White noise 4
  5. Fan 1
  6. Fan 2
  7. Fan 3
  8. Fan 4
  9. Fan 5
  10. Ocean 1
  11. Ocean 2

3. Good speaker quality and volume control

Strangely, I couldn’t find any information about the speaker wattage – either in the instructions or on the AST website. What I can say is that it’s louder than other portable devices I’ve used, and even some larger sound machines.

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

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

One final note is that the speaker can either point upwards or rotate so you can point it in a specific direction. This just adds a little more versatility in how you listen to the sounds.

4. Internal rechargeable battery

First of all, it includes a USB charging cable that you can leave plugged in if you choose.

But one of the LectroFan Micro 2’s 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 I’ve seen in any of them so far.

So you can take it outside, or leave it on a shelf or table without worrying about wall socket or USB port location in the night. It’s a convenient choice that I personally love having.

5. Bluetooth speaker and built-in mic

I’ve already mentioned it throughout the review, but with the flick of a switch and a quick pairing, you can play music from your smartphone, tablet or other Bluetooth devices.

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

You can also use it to answer phone calls as there’s a built-in mic that works well.

Criticisms


1. No auto-off timers

This was a criticism of the original and it remains the case with the LectroFan Micro 2. I think all white noise machines would benefit from having at least one auto-off timer, so it’s a shame there isn’t one.

2. Small buttons might be too fiddly for some people

A small, portable device like this 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.

I personally have no problem with them, so this will only be an issue for certain people. And as I mentioned above, at least this model now has a row of buttons for the volume and a row for the sound choice, rather than confusingly combining the two.


Verdict

The Lectrofan Micro 2 is a terrific little sound machine that ticks the boxes in terms of practicality and sound quality. The only thing I’d like to have seen included is an auto-off timer really.

Other than that, it does everything I’d like a travel sound machine to do – assuming you’re not interested in having a wider variety of nature sounds. If you like rain, birds, crickets etc, then you’ll either need to look elsewhere or use the Bluetooth speaker and provide those sounds yourself.

For such a small device, the speaker quality is unbeatable, as is the internal rechargeable battery. So I think it will be a while before a comparable device comes along that does a similar job so well.

    1. Hi Bas
      There are many ways to answer that question as they have some big differences. Personally, I’d be happy to use either of them as the sound quality is great on both. It’s probably a case of what makes one better than the other really depends on what you want from it, rather than one being obviously much better I think.
      Some differences that spring to mind are that the Evo has more sounds and louder max. volume, and a headphone jack. But the Micro 2 has the option to use it wirelessly and play your own music through it. So for me, I’d use the Evo in the home, but the Micro 2 if I planned on moving it around from time to time.
