A hearing implant reimagined

As a part of the Osia System, the OSI200 Implant allows sound to bypass blocked parts of the natural hearing pathway. The implant is placed under the skin where it's attached to a bone conduction (BI300) implant to send sound vibrations directly to the inner ear.

Piezo Power™ technology

The Osia System uses a special Piezo Power™ transducer that expands and contracts to create powerful vibrations.

Piezoelectricity has been used for years in many products like microphones, high-end speakers and medical equipment, but this is the first time it’s been used for this type of application.

One of the many advantages of the Piezo Power transducer is its ability to vibrate at high frequencies, within the area of sound most important for speech understanding.

Testing shows that Piezo Power technology provides powerful and consistent output performance.1

The power to hear more

The Osia System is for people with hearing loss up to 55 dB SNHL (sensorineural hearing loss). This means it delivers enough power to address a range of hearing loss levels, and it provides capacity should an adult or child's hearing loss worsen over time.

"I’ve followed Cochlear for quite a few years, and I knew they had a great reputation. So, I was pretty confident.

- Adrian, Osia System recipient

Designed for reliability, made to last

The Piezo Power transducer has a completely different design to traditional bone conduction transducers. With no movement between parts, the technology is well suited to deliver long-term performance and durability.1

Hear what you want to hear, not what you don't

The Osia System has been tested in trials across multiple clinics around the world. After one year, people who received the new technology showed significant hearing improvement, even in noisy environments.2


Osia users show a significant improvement in their ability to understand speech in quiet and in noisy environments.²
