How does Mimi work?

Mimi processes your music in a unique way. We mimic some of the function of the healthy human ear in a patent-pending process that is totally unique to Mimi music. We call this Mimification. As you might have noticed, with Mimi you hear every single nuance in your music more clearly. We support your brain in recognizing the contrast in sound by adding cues to your music.

Mimi processing replicates the function of the inner ear, and emphasises certain information in the digital audio signal. This eases the burden on the ear and ensures more information reaches the brain. Instead of cranking the volume, we replicate processes that have deteriorated over time, leading to a natural restoration of detail, richness, and contrast.

Testing Technology

We tested more than 1 million people globally and have the biggest database on hearing worldwide

Real-time Fitting

Enables real-time adjustment and perfect alignment between hearing results and processing

Unique Processing

Mimi processing replicates the function of a healthy ear, giving you pristine sound, with all its frequencies, detail and contrast restored.

Combining all this, Mimi gives users, regardless of hearing age or ability the best possible, personal, listening experience. Our unique sound processing has been developed by hearing scientists, researchers and music engineers. The technology behind Mimi is powered by our deep understanding of how people hear and what they don’t hear anymore. We gained this knowledge by creating the #1 Hearing Test for iOS and by testing more than one million people to date. Mimi’s technology is medically certified (CE), currently available in two Apps for iOS – Mimi Music and Mimi Hearing Test – and as the Mimi Inside SDK.


What is the Mimi difference?

Unlike traditional solutions which optimize the way sounds are played through features and hardware, Mimi optimizes the way sounds are processed relative to the hearing ability of each individual listener.

Our sound processing is as disruptive as it is powerful. Mimi goes way beyond an equalizer. An EQ attempts to modify music by making sounds at certain frequencies louder, or  in some cases reducing loud noises. This solution, however, fails to address the complexity of how humans experience sound. Most listeners don’t experience general audibility problems, but rather problems of understanding information, or picking out subtle details in complex mixes of sounds – think trying to pick out the flute melody in a classical music piece, or talking on the phone in the car. The issue is not too little sound, but rather too much, and too little information to decode it.

Mimi’s technology focuses our deep understanding of hearing science and the latest in psychoacoustics on exactly this problem, to optimise sound for every listener.

Unlike other solutions, Mimi takes a biological approach to enabling the most detail-rich sound experience possible while helping to protect your hearing at the same time.

Mimi uses and algorithms that tailor sound to your hearing ability based on the model of a healthy human ear. Our processing is specifically optimized to enhance subtleties in music that would otherwise be missed and cannot be restored with e.g. EQs or dynamic compression. It gives you the most realistic, natural, sound possible - and the closest approximation to perfect hearing.


What music/audio services work with Mimi?

You can listen to all the podcasts and music you’ve bought and stored in your device’s Music library. For other sources, we currently support Spotify and Soundcloud (& more to come soon). If you enjoy what you’ve so far experienced but want more, please give us a (hopefully) positive review on the AppStore and mention which service you wish to have as this will convince your service to getting themselves Mimified too.

You can learn more about the products we integrate here.

What do my hearing insights mean?

What does hearing age mean?

As we get older, our ears are aging too. That is why the expected hearing loss grade changes with every age group. For the young ones, we expect no loss at all – even with small amounts of hearing loss, they may end up at the lower end of the spectrum of their age group. Meanwhile older people can be expected to have some hearing loss already; so someone with no or mild loss will be at the top end of their age group.

I have no hearing loss, but I hear worse than most people in my age group. How can that happen?

This happens when we measure slightly elevated hearing thresholds compared to what is expected for your age, but these deviations may be too small to qualify as an actual hearing loss. Often, a little bit of hearing loss is the first sign of slow degradation, even though you do not yet experience any limitations in your everyday life. We believe you should still be aware of it. In particular, we recommend to watch out for changes in your results over time!
Please note that several factors might have skewed the measurements, such as the state of the headphones you used, the noise around you, or even your concentration! If you think your test setup might not have been optimal, you can always repeat the test in better conditions to make sure you obtain accurate information.

I have some form of hearing loss, but I hear better than most people in my age group? Why?

The good news: we measured lower hearing thresholds than what is expected for your age. However, this doesn’t mean you don’t need to take good care of your ears! Regardless of your age, if you have any grade of hearing loss, we strongly advise you to track your hearing capacity over time and get professional medical advice!


Is Mimi medically certified? 

Yes. Both the "Mimi Hearing Test" which tests your  hearing ability, and "Mimi Music" which personalizes sound to your unique hearing, have a certification. The Mimi Hearing App is a medical product in the European Union (Class 1, CE). The App has not been certified by the FDA (USA).
