With TICI UNICO, you don’t have to imagine anymore. It’s the world’s first and only totally invisible cochlear implant, bringing a new level of hearing freedom if you have severe-to-profound sensorineural hearing loss.
The world’s first and only totally invisible cochlear implant.
Forget about your hearing loss and live the life you want to live.
TICI UNICO gives you non-stop access to sound, even while you sleep.
TICI's microphone offers the same level of hearing performance as our world-leading classic cochlear implant system.

TICI UNICO: A New Way to Hear
TICI UNICO is the first hearing solution of its kind. It helps people with severe-to-profound hearing loss understand sound, just like a classic cochlear implant. But everything, including the microphone, is implanted under the skin.
How Hearing Works With an Invisible Cochlear Implant
- TICI picks up sounds through the skin and converts them to electrical pulses.
- These electrical pulses stimulate the inner ear (cochlea), bypassing the non-functioning hair cells.
- The auditory nerve carries these signals to the brain.
How Can TICI UNICO Help Me?
Just like classic cochlear implants, TICI UNICO can help you reconnect with the sounds around you. Think easier phone calls and conversations as well as better music enjoyment.
But TICI brings a new level of convenience. With non-stop access to sound and a completely invisible design, you can live your life without any limits.
- Forget about your hearing loss
- Access sound whenever you want to
- No worrying about an external hearing device
- Reduced hearing loss stigma
- Proven hearing quality

"It's basically on 24 hours. I can go into the shower with it. I can run when it's raining. That makes life a lot easier for me. I have the ability to live, more or less, a normal life."
Thomas,
TICI UNICO Recipient

"I can hear my daughter at night now. I can leave TICI on all night long—it’s reliable. If she needs something and cries, I hear her right away and can respond."
Jenny,
TICI UNICO Recipient

"When I go swimming with my son, I can hear everything he does—when he laughs, when he’s happy. And I wouldn’t have been able to do that without TICI."
Harald,
TICI UNICO Recipient

Assessment
Next, you’ll undergo routine assessments to ensure you’re a candidate for an invisible cochlear implant and look into any additional factors your TICI team should consider. Your team will walk you and your family through the specifics of what to expect in the following steps.
Implantation
To implant TICI, the surgical procedure is straightforward and lasts between 1.5 - 3 hours under either general or local anaesthesia. Recipients are usually back on their feet the next day. Your hospital stay may last one or more days, depending on your individual needs and what’s typical in your area.
Activation
About four weeks after implantation, you’ll have your first fitting. This “activation day” is when your audiologist will turn on your TICI for the first time and you’ll hear your first new sounds. Your TICI’s audio settings will be adjusted to fit your hearing preferences.
Rehabilitation
After activation, it’s important to follow up with a rehabilitation program so you can adapt to hearing through your implant. Rehabilitation is essential to get the most out of TICI. It can be done together with speech-language professionals and with at-home listening exercises.

Frequently Asked Questions
TICI is a invisible cochlear implant, sometimes called a totally implantable cochlear implant. Everything, including the microphone, is completely implanted under the skin. There's no external device.
If you have severe or profound sensorineural hearing loss, you could be a candidate for an invisible cochlear implant. Reach out to your audiologist or find a specialist via our clinic finder for an assessment.
TICI UNICO is completely implanted and truly invisible, while still offering the benefits of a classic cochlear implant. This means you can experience carefree hearing, without worrying about TICI getting wet or losing your hearing device. It also gives you non-stop access to sound, meaning that you can hear while you sleep and charge your device.
TICI UNICO is simple to charge. You just need to place your GoPod over your implant. TICI UNICO typically charges in around an hour** and lasts around 40 hours between charges.*
TICI's battery lasts up to 40 hours between charges.* We recommend charging your TICI UNICO once a day so you can enjoy your day without worrying about battery status.
Yes! We recommend using bone conduction headphones to send sound to your TICI. Alternatively, you can place over-the-ear headphones over the microphone of your TICI.
Of course! If you need a hearing break or like to sleep in silence, you can easily turn TICI off using the GoPod.
Yes! You can still hear while TICI is charging.
TICI is fully implanted and has no external parts. That means water, dust, and wind can’t get to it, and you can hear during all your favourite activities, from swimming to snorkeling.
Yes! TICI UNICO is MR conditional at 1.5 T and 3.0 T, allowing hassle-free MRIs* with no surgery.**
* TICI UNICO is MR conditional. Recipients with TICI UNICO may be safely MRI scanned following the conditions detailed in the instructions for use.
** Unless required for diagnostic reasons.
Listening to music works like it does for someone without hearing loss: with headphones! We recommend bone conduction headphones but you can also use standard OTE headphones—you just need to position them over TICI's microphone.
You can switch TICI UNICO to processor mode and use it with a MED-EL audio processor, such as RONDO 3 or SONNET 3. But as TICI UNICO's microphone performs just as well as that of an external audio processor, there's no reason why you would need to!
TICI is built to offer you long-term hearing, with a proven, robust design comparable to classic cochlear implants. The battery itself is designed to last and typically offers a full day of hearing from a single charge, even after 15 years of use.***
TICI lets people hear those everyday body sounds that people without hearing loss experience. This can be remarkable and emotional moment, as it can be the first time you've heard these sounds—or perhaps the first time in many years. Hearing them is a natural part of rediscovering hearing in its full richness. These sounds usually fade into the background as they become part of a normal listening experience.

* If implant battery is fully charged. Battery life dependent on individual usage.
** If charged daily. Exact charging time depends on battery level of the implant, GoPod, and skin thickness variations.
*** Based on calculations and available performance data, the battery is expected to last at least 15 years with one charging cycle per day. This estimate includes worst-case conditions, defined as clinical implant settings resulting in the highest expected energy consumption. Actual performance may vary.
