Avantek Rechargeable White Noise Machine Review

avantek rechargeable white noise machine

The new Avantek white noise machine is an excellent improvement on the previous version, which was already one of my top rated sound machines.

The most notable differences are:

  • It has a rechargeable internal battery that will run for 10 hours.
  • There’s a headphone jack for private listening.
  • It has an impressive choice of 30 sounds, 10 more than the old model.

In my video review below, you can see the Avantek in action and listen to all 30 sounds. And there’s my full write-up below that.

The good points

1. Excellent sound quality and variety

There are too many sounds to rate individually, so here’s a summary of my opinion:

  • The speaker quality is excellent. All 30 sounds are crisp, even on a loud volume.
  • I liked that the popular sounds have variations, such as two ocean and three running water (with and without added birds).
  • It’s great to have 6 fan and 6 white noise variations. They include deeper pink noise, which for many people is more relaxing to listen to.
  • My least favorite were the ticking clock, dripping water and heartbeat. However, for some people and young children, they could be useful for sleep.
  • There are some fun sounds unique to this device, like echoing frogs and water bubbles.
  • The sounds are recorded live, so are authentic and ‘non-looping’. They are, of course, on a loop since they are recordings. But you just don’t hear any pause or click before they start again.

2. Built-in headphone jack

Strangely, very few white noise machines have a headphone jack. So the built-in 3.5 mm headphone jack is an excellent addition.

It means you can listen privately when working or studying. And if you share your bed, your partner won’t complain about the thunder or crickets!

I also find that listening to white noise on headphones helps block even more external sound at night.

3. Rechargeable internal battery

Again, not that many sound machines have a wireless play option. And if they do, it’s usually two or three AA batteries.

The Avantek has a built-in 2600 mAh lithium battery. That allows for 10 hours play, even at maximum volume. You can also leave it playing with the included power adapter and USB cable.

For me, this is a key upgrade to the previous Avantek model. Having the option to position it wherever you like, without worrying about power outlets, is very convenient.

4. Good volume range and masking of unwanted noise

Like the old model, there are 30 incremental volume controls. The loudest is 115 dB, which is very loud on some settings, like birds.

This is more than enough volume and sound choice to mask most external noise. I tested it in both my bedroom and study, and found that even on medium volumes, it capable cut out external noise like music, television, people talking and cars.

5. Memory function

The Avantek will automatically start with your last set volume, soundtrack, and timer. With 30 sounds to potentially go through, this is a useful feature that will save you time.

6. Sleek, compact and user-friendly design

There are a handful of design points which I liked a lot:

  • The new round design looks more elegant on a table that the square shape.
  • The new touch buttons are silent compared to the previous ‘clicky’ buttons.
  • An Anti-slip bottom keeps it in place on the nightstand.
  • It’s small, taking up little space on a nightstand. But it’s also robust and feels like it was made from solid, quality materials.

7. Choice of auto-off timer or continuous play

You can leave it running constantly if you like. Or there are one hour incremental auto-off timers from one to a maximum of seven hours.

Since it’s advised not to listen to white noise for longer than necessary, this is a useful safety feature, especially for children.

8. Portable

The machine is small and light, so excellent for traveling. It measures just 4 x 4 x 2 inches and weighs 15.5 ounces. This puts it in the lower end of the size spectrum of the white noise machines I’ve used.

It also comes with a fabric drawstring carry pouch to keep it in good condition.

This is one of those rare cases when reviewing a product where there were no obvious issues.

Compared to the average white noise machine out there, there’s really nothing obvious to complain about. Still, there are a few points that came to mind:

1. No richness feature

It would have been good to include a ‘richness’ feature that a couple of devices, like the Sound+Sleep have. It would be nice to combine crickets with the fireplace, for example.

Having said that, there is water with birds and water without birds. So they have tried to cater to more than one taste.

2. Too many nature sounds compared to white noise

Personally, I’d prefer more variety of white noise and fan sounds rather than so many nature sounds. With 6 white noise, 6 fan, 18 nature and ambient sounds, the balance could be better.

3. Sound descriptions could be better

I think the manufacturer could have described the white noise better, rather than simply listing white noise 1 to white noise 6. The LectroFan, by way of comparison, does this very well and specifies if it’s pink noise or an industrial fan.

4. Definition of non-looping is ambiguous

Non-looping gives you the impression that there is zero looping, which isn’t true. I’d like the manufacturer to be clearer about this, and state exactly how long each recording is.

Though to be fair, I don’t know of any company that does that yet!


It seems the manufacturer has listened to criticisms of the previous machine and created a new model which gets just about everything right.

I love the fact that there’s so much variation – there really is a sound to cater to every possible taste. Whether you prefer white noise, fan sounds, nature sounds or even a ticking clock, you should find several sounds you enjoy.

Most importantly, I found it very capable of blocking out the kind of noise that disturbs me at night or when working. And with the built-in headphone jack, you can achieve even more sound masking if you need it, and even deal with a snoring partner.

Overall, this is an excellent device and now my equal favorite with the LectroFan. But if you’re looking for a machine with the best possible vartiety of white noise and nature sounds, this is my top choice.


On Amazon, it hovers around the $40 mark in the U.S. and £37 in the U.K., for example. This puts it in the middle price range for white noise machines.
