What is behind QuietOn 3.1 performance?
The updated QuietOn 3.1 earbuds take users on a seamless journey to quietude by creating a smooth, quick transition to active noise cancelling mode from the moment they’re removed from the case. While they begin in a hearing mode, in less than 20 seconds you can hear the active noise cancelling (ANC) turning on.
QuietOn 3.1’s ANC technology eliminates ambient sounds by automatically generating opposite waveforms to nullify the low frequencies, resulting in a much quieter and more peaceful environment for sleep.
Some of the most common noises that interrupt sleep are low-frequency sounds from home appliances, traffic or street noise, snoring partners and noisy neighbours and QuietOn 3.1 sleep earbuds are designed to decrease the noises from all above.

Eartips material
QuietOn 3.1 eartips are made of memory foam material. This custom designed material is optimized to gently expand to make the airtight seal but with minimal force to maintain the comfort that people need for the overnight use. Even though this material is extremely comfortable it has optimal acoustical capabilities to work with active noise cancelling.

How Active Noise Cancelling works
Active Noise Control (ANC), Active Noise Cancelling (ANC), and Active Noise Reduction (ANR) are methods where an unwanted sound is reduced by adding another sound specifically made to cancel it out. Our active noise cancelling earbuds use a microphone to sample the sound, and a speaker to create a phase-shifted sound that cancels the original sound.

The performance of QuietOn 3.1 Active Noise Cancelling earbuds compared to that of conventional foam earplugs is visualized in the graph below. No total silence created, but optimal environment for sleeping.

The graph illustrates how well passive and active noise cancelling reduce the noise. It depicts the noise amplitude in the frequency scale, throughout the entire sound spectrum, but especially in the range between 200-800Hz active noise cancelling is particularly effective.
Passive noise cancelling devices such as foam earplugs perform well for frequencies over 1kHz, however they are not working effectively in the range where you would need them most: Low frequency noise waves, which are long and go through the walls and earplugs.
The solution for those is active noise cancelling – The graph demonstrates how well the low frequency noise is reduced with QuietOn 3.1. Yet, ANC does have limitations and no ANC device works well over 2kHz frequencies. It is just the law of physics processing and audio components have delays.
That’s why QuietOn’s unique approach of combining ANC and passive noise reduction gives the best possible results when you cannot sleep because of sleep disturbance.
Here you can learn more about the performance tests our earbuds go through, to ensure that we offer nothing but technological excellence to you.
QuietOn 3.1 is designed for the ear anatomy
For a normal sized adult’s outer ear, the shell of the earbud typically fits inside the concha, between the crus of helix and the antitragus. Because of this position and the slimness of the earbud, side sleepers don’t feel the pressure.
Another important feature is how the shape of QuietOn 3.1 Active Noise Cancelling earbuds is designed to reach the ear canal without stretching the tragus.
The width of the ear canal varies from person to person. Given that QuietOn 3.1 comes with four different sizes of foam tips, it is ensured that the device fits best into different sized ear canals, ensuring the best possible help when you cannot sleep.

ANC in tiny technology
- Microphone takes a sample from the outside noise.
- The tiny active electronics inside the earbud creates a phase-shifted and equalized sound.
- The phase-shifted sound is then played through a speaker thus cancelling the original noise.
- The energy for the device is provided by re-chargeable battery.
- The soft memory foam tip ensures a tight fit in the ear and handles the passive noise cancelling.
With our three generations of earbuds for sleeping, QuietOn is proud to be the smallest active noise cancelling device on the market today.

Reduce the snoring noise
QuietOn provides optimal noise reduction across the whole audible spectrum. They are most effective at low frequencies such as snoring or ambient sounds coming through walls. With QuietOn 3.1’s ANC, the point is not to force your body to quit snoring. Instead, it provides another way around the problem and people are finding it to be useful when they can not sleep.

Sleep in quietude surrounded by city and neighbourhood noise
The feeling when you can not sleep because of noise disturbances, such as traffic noise or music coming through walls is hardly bearable. QuietOn 3.1 active noise cancelling earbuds block these frequencies effectively and provide you the soothing and relaxing quietude you need for a good night of sleep and feel refreshed the next morning, despite the high noise level in urban areas.

The smallest earbuds for sleeping
QuietOn 3.1 is around 3 times smaller than Apple Airpods Pro™, a product which could more or less could be perceived as the “industry standard”, when it comes to the size of consumer market wireless earbuds.
QuietOn 3.1 is an ANC custom made solution with a battery that is small in size and high power efficiency. The battery life is exceptionally long with 28 hours on single charge. QuietOn 3.1 is the only device worldwide in this scale providing excellent noise cancelling performance as well as premium comfort.

The wireless, free from connectivity QuietOn 3.1 is equipped with foam tips (XS, S, M, L), USB-C cable and last but not least, the charging case. A Fully charged case provides energy for the earbuds for a week.
The earbuds’ lithium-ion batteries last around 28 hours on single charge, giving 3 full night sleep without worrying about the battery.
Frequently Asked Questions
QuietOn 3.1 uses Active Noise Cancelling technology to eliminate low-frequency sounds like snoring, traffic, and home appliances. A built-in microphone samples the sound, and the earbuds produce a phase-shifted sound that cancels the original noise. This combination of ANC and passive noise reduction creates an optimal sleeping environment.
Yes, QuietOn 3.1 earbuds are designed with a slim, ergonomic shape that fits snugly in the concha of the ear, making them comfortable for side sleepers. The memory foam eartips also provide a gentle, airtight seal without causing discomfort, even during extended overnight use.
QuietOn 3.1 earbuds offer up to 28 hours of battery life on a single charge. The included charging case provides additional power, allowing for a full week of use without recharging, depending on your usage.
QuietOn 3.1 earbuds are particularly effective at reducing low-frequency noises, such as snoring, traffic, and sounds coming through walls. While they excel at canceling these frequencies, they also combine passive noise reduction for higher-frequency sounds, offering comprehensive noise management.
No, QuietOn 3.1 earbuds are completely wireless and free from connectivity requirements. Simply remove them from the case, and they automatically activate. There’s no need for pairing, apps, or adjustments—just pop them in and enjoy restful sleep.
