“What is personalized audio?”

This year, major events happened in the sound space which indicate that your senses will have a higher importance in the upcoming years. On September 7th, Apple announced the Wireless version of their EarPods, called AirPods. Though other companies already opened up the hearable market, when Apple picks up on technology like this the impact on the market will be significant. Just this week the headphone (and personalized audio) company Even announced their partnership with music streaming service Napster. It shows that the topic of personalized audio has arrived in the mainstream market and that is excellent news for all the ears out there.

This article is for you to get a better understanding and overview of the market and the potential that goes along with customising your audio experience. We’ll be summarising what personalized sound is, and you’ll find small pieces on different companies in the field. If you want to know who we are and what we normally do, visit our website or hear for yourself.


Personalized Audio: A Quick Explanation

To make the concept of personalized sound more comprehensible, let’s compare it with classic prescription sunglasses. Prescription glasses adapt the things you see to your vision abilities, so your imperfections get compensated. You can set your own preferences by choosing the lens color. This is basically what personalized sound is, with the difference being that it is digital and for your ears instead of your eyes:
The things you hear can possibly be adapted to your hearing ability (how well your hearing works), your personal preferences (more bass, more treble) but in addition also to the environment you are currently in (e.g. while commuting).

Why does Personalized Hearing become more and more important?

Put simply, the things we use our senses for are changing. We use technology differently than we did 10 years ago and this new form of usage requires all our senses, and this is exactly why Personalized Audio will become more prominent. Earlier this year, Apple introduced their Apple AirPods — wireless earphones — which means you won’t need to hold your phone as much anymore. Therefore, hearing and voice become more important than the ability to view and touch.

Most likely you do not know many people who own or use wireless earbuds… yet. Hard to imagine? — Just think about how many people owned a smartphone just a decade ago.

Also Siri recently started to talk to you, first on your phone but now also on your computer. Or take Amazon’s Alexa: What a great personal assistant — if you can hear her. And I could go on and on with this, as there are a million use cases already.

What is the potential scope of Personalized Sound?

There is a broad range of positive effects for everyone if sound personalization is done right: First, it simply sounds better because it is adapted to your hearing ability, your preferences, or/and your environment.

Second, people who suffer from mild to severe hearing loss are able to hear music again without too much distortion and without the need of wearing the hearing aid. Removing the stigma around hearing loss will also positively affect more than one billion people worldwide.

Coming back to the comparison with glasses: Personalized sound has the potential to make “hearing auxiliaries” as cool as a pair of glasses.

Please read below a selection of companies which are aiming for this to happen!

“Aumeo — Hardware works well because it makes the topic more tangible”

Aumeo Audio created a device that you can put between your headphones and the audio source you’re listening to. Tailoring the audio to your hearing takes about a minute according to their website, and can be done through their app.

Choosing a hardware solution that is separate from the headphones is an interesting approach. It means that you can listen to any audio source, while still using your favourite headphones. The main drawback is having to carry another device with you. Still, hardware works well because it makes sound personalization more tangible for people. With this little ‘black’ box, you intuitively know where the audio is changed to fit your hearing.

Providing their solutions in software might be an interesting path for Aumeo going forward. With the advent of the AirPods, and the trend of wireless audio that also Doppler and Bragi play into, having a physical device that you can only use with wired headphones will not be relevant anymore. The question is if their processing and fitting technology is unique enough to be able to be a pure software company? Hearing loss is not just the loss of sensitivity to frequencies, and having a pure software solution means that there is less headroom to play with the sound.

“Doppler earbuds show great potential in becoming an intelligent piece of tech in your ear”

Doppler is the company behind the wireless earbuds called Here One. The company wants to “redefine the way we engage with sound through technology”.

Doppler’s products attract users because they let you control live sound with an app that adjusts the earbuds with “real-world volume control, EQ, and sound effects”. Not only are you able to listen to your music wireless but you can also play around with live-sound, take phone calls or, what I found really interesting, amplify speech. Speech amplification can be a big bonus to people with hearing problems, while not being immediately identified as hearing impaired.

The company claims that you can “personalize” the sound to your needs because “we all hear the world differently”. Personalization in this case can mean the way you use the earbuds (music, live-sound, speech enhancement) and the level of EQs and sound effects you apply. Since Doppler is one of the first companies that provides such a hardware product, they have received a lot of attention from the media.

The earbuds show great potential in becoming an intelligent piece of tech in your ear. Remember that movie Her? Combining with the fact that they look good, are really tiny and claim to help with speech amplification, this could attract many customers indeed.

Business-wise the company has an impressive track record. After successfully launching a Kickstarter campaign which collected $635,189, they raised another 50 million dollars in four rounds and grew to over 50 employees.

“Human’s shape is inspired by the human ear”

Another company that claims to have invented “the future of audio” is “human inc”. The approach is reminiscent of Doppler’s Here One but still it aims to be different. Its shape is inspired by a human ear and it intentionally looks like a earmuff, covering the whole ear when put on and thus clearly visible for everyone.

Human headphones let you listen to music wirelessly, take phone calls, switch and blend between live sound and music just as the Here One. In addition the company says it has longer battery life, a touch control and a bunch of extra features such as sleep tracking or body monitoring. It even let’s you use the headphones as speakers when put on a table for example.

The company started with an Indigogo campaign (just as Doppler did on Kickstarter) and raised $518,525. Another 5 million dollars have been raised with investors.

For both Doppler and Human, the challenge lies in the hardware part of their business model. Building, improving and innovating hardware products that compete with the experience, quality and price of trusted players is a massive challenge.

In the end, if choosing a hardware device, the users also have to decide if they want a small, rather unobtrusive earbud which is controlled with an app or rather headphones that cover the entire ear, attract a lot of curious views and have touch control.

“Even Singular Sound wants to take your headphone experience up a notch”

Even recently released their Even Earphone and Even H1 headphone set. Their products allow users to hear personalized sound on a hardware device — challenging the current market of headphones, which is dictated by good looks.

They emphasize that no one’s hearing is the same; not even both of the same person’s ears, and that personalized hearing is the solution. As hearing abilities are unique, these devices promise an extraordinary sound experience by tuning it to one’s hearing via the EarPrint.

The EarPrint is a new terminology that expresses the uniqueness of one’s hearing, just like a fingerprint. It embodies the user’s hearing profile which is then used to personalize one’s sound experience. The term is simultaneously used by software company Mimi Hearing Technologies and more.

The company is among the first players in bringing the terms “personalized sound” and “earprint” to a bigger audience. For the sound and music space, these terms are rather new and it will still take time until everyone will understand that the times of mainstream sound are over now.

“Decibel Therapeutics are Striving for Perfection”

Hair cells are the structures in the inner ear responsible for converting the mechanical vibrations associated with sound into neural code. They are also responsible for the active properties of the inner ear which assist the listener when listening in noisy environments.

Within the hearing space, Decibel Therapeutics stands out as a company that is looking at therapies to protect and restore hearing through therapies that directly affect the function of these essential structures. Their publication list suggests that they will be looking at interventions more in the pharmaceutical domain rather than preprocessing audio for the individual as is done with conventional hearing instruments.

The precise embodiment of the products on the horizon is not entirely clear, but they publicly state that their “unique capabilities encompass animal models, drug delivery to the inner ear, imaging, inner ear PK/PD modelling and measurement, bioinformatics, genetics, and target identification”. Reliance on electronic devices for hearing will always have some limitations compared to audition as nature intended. Decibel Therapeutics are striving for perfection. We look on with anticipation.
