Sound experience
Clear sound. Bright future
With the Osia 3 Sound Processor, we aim to empower you with a hearing experience as true to life as it can get. To help you feel truly unstoppable.
Power and signal processing help you take in the crisp, clear sound of voices and filter out noise in the car or a crowded space. And access to a broad, dynamic range of sounds across frequencies helps you hear the vibrant, nuanced sounds that enrich life.3 This means what you hear–from chirping birds to live music–isn’t muffled or distorted by technology.
Power to hear more
Delivering even more power than the previous generation, the Osia System supports better hearing outcomes in many different environments.1,2
Better sound quality
In a study, 93% of users preferred the sound quality of the Osia 3 Sound Processor compared to the previous generation–with especially high ratings for listening to music.1
ForwardFocus
This new feature helps you focus on the sounds and speech in front of you, for improved word recognition in noisy situations.1
Adaptive signal processing
Our SmartSound® iQ signal processing filters out background noise and adapts to changing environments as you move through your day.
Large dynamic range
In a hearing device, a large "dynamic range" (the span between the softest and loudest sounds) means soft sounds are amplified while louder sounds remain crisp and less distorted.3
Wide bandwidth
A broad range of frequencies helps deliver rich, unmuffled sound at higher frequencies, like a child’s voice or a bird’s songs.
