QuietOn Sleep Review the Active Noise Cancelling Earbuds

As part of my research for this QuietOn Sleep Review, I managed to secure more good nights’ worths of sleep than normal with these state-of-the-art, noise-cancelling earbuds. QuietOn Sleep is not perfect but it is innovative and it does deliver on its promises; perhaps that’s one reason why their original Indiegogo Campaign was one thousand per cent funded and they are still going strong unlike the Bose Noise Cancelling Sleepbuds which were withdrawn from sale then replaced with a Bose Sleepbuds II product that I couldn’t get to work! Sometimes the names you’ve heard of are not the best.

Hopefully, you will appreciate this genuine QuietOn Sleep Review, the pictures show I’ve actually used the latest generation product. NB: There are two versions, don’t buy the older version from pre-2019! Neither am I reviewing the generic Quieton earbuds, I’m looking at the SleepBuds.

Updated: February 14, 2021

The QuietOn Sleep sleepbuds do have some issues and are not the panacea for everyone, everywhere to get a perfect night in bed every single night. BUT THEY CERTAINLY HELPED ME…quite a lot!

You insert the mostly-comfortable earbuds and listen to the sound of the foam adjusting in your ear. You press the button and then…nothing. And that’s good, right? No sound.

The QuietOn Sleep really does stop a lot, but not all, of the ambient noise that keeps many of us awake and, yes, that includes your partner’s snoring.

I didn’t expect perfection or perfect silence but the QuietOn sleep was better than my expectations.

For those who have difficulty sleeping (me), the value of a good night’s sleep is immense. QuietOn Sleep scores HIGHLY there but having to fiddle too often with the on/off button spoiled my enjoyment of the product. Most notably it is supposedly auto-on when taken from the charging case but I’m never sure if that happens or not, and then pressing the on/off button to check is fiddly.

Best Use: For me, the best use with the QuietOn Sleep reviewed here was getting to sleep, once I’m asleep I generally sleep well but pings, pops, stores and general ambient noises are the ones that stop me from falling asleep and QuietOn helped me a lot there.

Are they cheap for you at Eur199? Personally, I’d pay Eur499 for a product that guaranteed a good night’s sleep, every night. In a few months worth of usage, I’d say I easily got Eur200-worth of quality sleep.

If you expect QuietOn Sleep to give you perfect sleep every night you will be disappointed, if you want QuietOn Sleep to improve your sleep on two nights each week then your expectations will be exceeded. You can monitor the improvement in your sleep with a sleep tracker like Circular Ring or with the sleep-tracking on a sports watch like the Polar Vantage.

QuietOn Sleep – Who is it for?

The clue is in the name. QuietOn Sleep is a sleep-aid. We all sleep.

As well as those of us looking to sleep better by reducing unwanted environmental noise (aka snoring!) it doubles up as product to use in the day to reduce many of the unnecessary noises that blight our concentration throughout the day.

How Does QuietOn Sleep Work?

The sounds that surround us come in waves. You might remember when you were 14 and at school that ‘anti waves’ will cancel out wave noise to a degree. That’s the broad principle behind the clever part of how QuietOn Sleep works and QuietOn also include a comfy earbud tip to physically stop some noises reaching your eardrum.

There are 3 general approaches to improving sleep quality with an ear-based device

  1. BLOCK the noise getting in – QuietOn Sleep partially does this ie it reduces the environmental volume level as would do any earbud, albeit to varying degrees.
  2. PLAY alternative, relaxing sounds like the sound of rain or white/pink noise. – QuietOn Sleep does not do this at all. They are NOT regular earbuds that play any kind of music.
  3. CANCEL AMBIENT NOISE – QuietOn Sleep aims to do this over a range of sound frequencies BUT NOT ALL.

How QuietOn Sleep works in more detail!

I’ll show my own tests later. For now, this first chart from QuietOn shows how sounds under 4kHz and below 40db are largely eliminated from QuietOn’s definition of ‘snoring noise’ and the second, independently-sourced chart broadly shows that QuietOn’s choice of frequencies where snoring occurs is ‘about right’ (Source:

Unboxing, Contents & Comparisons – QuietOn Sleep Review

You get two earbuds and a charging case.

There are also a USB cable and a range of foam ‘Tips’, these are the interchangeable foam bits that go inside your ear and different sizes are provided to get a comfy fit.

The aesthetics and attention to design details on the sleep buds are not perfect and certainly not as polished as you would find on your music earbuds but it’s OK nevertheless.

Similarly, the charging case is perfectly fine and works perfectly well but the design can be improved.


The charging case/carry-case contains a battery which can be charged at any time ie whether or not the earbuds are in your ears or in the case.

The QuietOn earbuds can only be charged when in the charging case and the charging case must either have a charge in its battery or be plugged into a power source itself. This charging setup is not innovative and is used on several other sets of music earbuds that I own; nevertheless, it’s still a ‘good idea’ regardless of who first thought of it!

The main benefits are that the charge in the earbuds can be EASILY topped up when not in use and you don’t have to be THAT organised to remember to charge them. You just put them back in the case routinely each morning. You won’t want to leave earbuds lying around when not in use as this might be a good way to get an ear infection…which is not pleasant. As well as keeping dirt out of them the case also prevents damage if you intend to use them away from home.

TIP: Leave the charging case plugged in all night and put the sleepbuds into it when you get up and take them with you to work if you prefer

Size Comparisons

Here are the QuietOn Sleep earplugs compared to a Jabra Music earbud and a silicone rubber earplug (for swimming). As you can see the QuietOn compares favourably in terms of size. They all seem relatively small, don’t they? Yet size IS a very important factor if you sleep on the side of your head. Placing something ‘large’ in your ear all night and compressing it into a pillow WILL turn out to be uncomfortable.

Here are some indications of fit and size. The first, female, ear is very small and the bud maybe a tad too big. That ear has the buds inserted correctly. The second image shows a smaller than average male ear where the sizing is fine but you can see here that the earbuds are maybe slightly too big so restricting the ability to properly fit into the ear canal and this then makes the fit slightly ‘wonky’. The final, third image shows much larger Jabra music buds but notes how the flat surface of these is much further away from the head and sticking out of the ear – these are unsuitable for sleeping, IMO.

Is QuietOn Sleep Comfortable?

Generally, I’d say that “Yes” they are comfortable. If I tried to sleep on my side with my head in a certain position then there was some discomfort in that position. At which point I moved my head a little 😉

They generally ‘stay in’ but once in a while might come out of the ear.

Does QuietOn Sleep Eliminate All Noise?

A: No.

QuietOn makes this claim about what frequencies and what volumes are dealt with “QuietOn Sleep is able to cancel the low and mid-frequency noises from 100Hz – 2,000Hz up to 30dB from the original noise level.

Thus, some noise can be heard but some frequencies appear to me to be eliminated and others GREATLY diminished.

I used to use my swimming earbuds sometimes when sleeping and they DO eliminate a significant amount of noise by forming an airtight seal, however, swimming earbuds become notably uncomfortable after prolonged wearing at night. To make matters worse, the swimming earbuds seemed to slightly damage my inner ear when sleeping with them and then I found there to be a high chance of a PAINFUL ear infection (acetic acid/vinegar applied with your little finger is the cure). QuietOn Sleep uses generic Foam Tips which are VERY gentle on the inner ear and I had no issues with damage nor subsequent infections.



QuietOn Sleep – My Tests

The most simple test is whilst sitting in an office. You put the earbuds in your ear when they are turned off, get used to the ambient noise and then turn them on. There is an obvious difference but you can still hear certain sounds.

On two different days in different ambient conditions, I tried two online sites that play different frequencies of sound

  1.  With QuietOn noise cancelling earbuds the sounds stopped at 4-8,000Hz. Without QuietOn Sleep I heard a noise to 9-12,000Hz.
  2. Sounds for me started to be audible at 97 Hz, mostly stopped at 9500Hz, definitely stopped at 10500Hz. Without QuietOn Sleep I could hear to over 14000Hz

The overall lowering of the Volume was harder to judge. I would guestimate that the audible frequencies were reduced to 20% or lower with QuietOn Sleep. ie reduced by at least 80%

The results will be affected by the quality of my PC’s speakers and other factors.

You could try either of those sites to prove to yourself there is a difference in relatively controlled conditions. However, as I say, the reduction in sound should be obvious when QuietOn Sleep is turned on.

QuietOn Sleep as part of your quest for a good night’s sleep

I’ve found a notable benefit of using QuietOn Sleep regularly. If you want some other suggestions for a good night’s sleep then try these

Other people swear by these ideas, some of which I came across while researching other suggestions for this QuietOn Sleep Buds Review

Q: What are the best earbuds for sleeping?

A: Cheap Speedo swimming earplugs eliminate most noise but are uncomfortable, can cause infection and degrade after several weeks

Q: What are the best noise-cancelling headphones for sleeping?

A: I don’t know of any noise-cancelling earbud that is better than QuietOn Sleep

Q: Do Earplugs help with snoring?

A: Absolutely, yes.

QuietOn and CV19

QuietOn Sleep’s noise-cancelling technology make it ideal for use when working at home where the hum and buzz of your household’s daily activities might disturb your work efforts. QuietOn SLEEP mutes much of the noise around you but still allows for ‘hear-through’ when you need it.

There is also a DENTAL version planned but for now, this second-generation product is QuietOn Sleep.

Compared to QuietOn Original, QuietOn Sleep:

QuietOn Sleep vs Bose SleepBuds and Bose SleepBuds Gen 2

The Bose product is no longer sold and has been withdrawn from sale.

I did a review of the SleepBuds Gen 2, they were awful and I just couldn’t get them to work (pair properly).
