A hearing implant reimagined

The Osia OSI200 is placed under the skin and works by bypassing damaged areas of the outer and middle ear, which sends sound directly to the inner ear. The implant is attached to the BI300 which is Cochlear’s latest titanium implant featuring TiOblast™ surface technology. The implant is designed to promote faster and stronger integration to the bone (through a natural process known as osseointegration).

Piezo Power™ technology

The Osia's System Piezo Power™ transducer (the part that vibrates) is designed to expand and contract to send powerful sound vibrations directly to your inner ear. This transducer has no movement between the inner workings of the implant, which provides you with reliable and consistent hearing performance over time.2

Lifetime testing shows that Piezo Power technology provides powerful and consistent performance over time.2

The power to hear more

The powerful transducer can help those with hearing loss up to 55 dB SNHL*. This means it can help address a range of hearing loss levels and can help you hear now as well as if your hearing loss gets worse over time.

Osia recipient Adrian and his friend talk as they sit on a porch swing

"I’ve followed Cochlear for quite a few years, and I knew they had a great reputation. So, I was pretty confident. I’m a bit adventurous, so I thought, why not?"

— Adrian, Osia System recipient, Australia

Significant improvement in hearing

We’ve tested the first generation Osia System in trials across multiple clinics around the world. After one year, people who received the new technology showed significant hearing improvements, even in noisy environments.1,3

Osia System users show a significant improvement in their ability to understand speech in quiet and in noisy environments.1
