The Cochlear™ Osia® System.

The Cochlear™ Osia® System is the world’s first osseointegrated, steady state active system that can help those hear better who struggle with with single sided deafness, conductive and mixed hearing loss. The Osia System uses the body’s natural ability to conduct sound through bone conduction.

Blending hearing technology with human capacity. Seamlessly.

When developing the Osia System, we looked to the body for inspiration and worked hard to keep things simple. The Osia System utilizes our natural ability to conduct sound through bone conduction, helping you hear speech in difficult, noisy situations where you may struggle the most.

Osia® 2 Sound Processor – built for comfort and durability.

The slim, off-the-ear Osia 2 Sound Processor is light and comfortable to wear. As an all-in-one unit, you simply place it on your head behind the ear and you’re ready to go. With a choice of five color options that you can easily interchange, you have choices to fit your preferences.

The Osia 2 Sound Processor’s durable design is dust, drop and moisture resistant. The sound processor can even be used in the water with the Aqua+ accessory that easily covers the Osia 2 Sound Processor to make it waterproof down to almost 10 feet.*

The power you need with Piezo Power™ technology.

The more power a sound processor has, the greater opportunity you have to hear more sounds. Additional power capacity can be critical if your hearing changes over time, which is why the Osia System is designed to help those with a hearing loss up to 55 dB SNHL.**

This level of power with the Osia System is due to our innovative Piezo Power transducer. This transducer (the component that creates the vibrations) is placed discreetly under the skin and is designed to expand and contract to create powerful sound vibrations that are sent directly to the inner ear through the bone. One of the many advantages of the Piezo Power transducer is its ability to vibrate at high frequencies, which is important for speech understanding. And, with no movement between parts, the transducer is designed to deliver long-term performance and reliability.1

How the Cochlear™ Osia® System works

The Osia System is a brand-new hearing implant that uses digital piezoelectric stimulation to send sound naturally to your inner ear through bone conduction.
