Phonak continues to lead the hearing industry with innovative technology designed to help users hear more naturally and communicate with confidence.
Two of its latest premium hearing aid models, the Phonak Audéo Infinio and Phonak Audéo Infinio Sphere, offer outstanding sound quality, connectivity, and comfort.
However, while they share many similarities, the Sphere version introduces a major breakthrough in speech understanding in noisy environments.
This article explains the key differences between these two models and helps you determine which one best suits your hearing needs.

The key difference: DEEPSONIC AI Technology
The biggest distinction between the two models lies in the Phonak Audéo Infinio Sphere's dedicated AI processor called DEEPSONIC™. Unlike standard hearing aids that rely on a single processor for all functions, the Sphere includes an additional chip specifically designed for speech separation and noise management.
This technology powers Spheric Speech Clarity, a feature that continuously analyzes incoming sounds and helps distinguish speech from background noise in real time.
Instead of simply reducing noise, the system focuses on identifying and enhancing spoken voices, making conversations clearer in challenging environments.
So, which one should you choose?
- Phonak Audéo Infinio: The Phonak Audéo Infinio is ideal for users seeking exceptional sound quality, reliable connectivity, and flexible pricing options for everyday listening situations.
Phonak Audéo Infinio Sphere: The Phonak Audéo Infinio Sphere is best suited for users who regularly encounter difficult listening environments and want the most advanced speech-in-noise technology available from Phonak. Its dedicated AI-powered DEEPSONIC chip provides an additional level of speech clarity that can make a significant difference in busy social settings.
