Phonak Audéo Sphere Infinio Ultra

Phonak Audéo Sphere Infinio Ultra - AI hearing technology

The Phonak Audéo Sphere Infinio Ultra is currently the most advanced and highest-end hearing aid from Phonak. With the help of artificial intelligence, speech is highlighted with particular clarity and intelligibility, even in noisy environments. The device automatically detects the direction voices are coming from and reliably separates speech from background noise. With the new Infinio technology, everything sounds more natural and listening is noticeably less tiring. The Phonak Audéo Sphere Infinio was launched in fall 2024 and received the "Ultra" firmware update in fall 2025.

• Core innovation: The Phonak Audéo Sphere Infinio Ultra features two separate chips. This enables AI-powered sound processing in real time, allowing speech to be extracted more clearly from any direction. The software recognizes the environment and automatically switches to the appropriate processing mode. This enables automatic, context-aware optimization without manual intervention.
• Connectivity: The Phonak Audéo Sphere Infinio Ultra can pair with up to 8 Bluetooth devices and connect to 2 devices simultaneously. The technology enables uninterrupted, hands-free phone calls, music streaming, and connection to the myPhonak app over twice the range.
• Water and dust resistant: The IP68 certification makes Phonak hearing aids resistant to moisture and dust.
• Powerful: The Phonak Audéo Sphere Infinio Ultra promises a full day of hearing performance. If the battery starts running low, you can recharge up to four hours of power in just a short time*.
• Difference from the Phonak Infinio Ultra: The Phonak Sphere Infinio has an additional second AI chip (DeepSonic), which separates speech from background noise much more effectively, especially in challenging situations. This makes the hearing aid significantly more capable, but also slightly thicker than the standard Infinio model. Two chips also consume more energy, so the battery life of the Sphere Infinio doesn't quite match that of the Infinio. The Sphere Infinio Ultra is ideal for people who want uncompromising hearing.

The 2 performance levels

The Phonak Audéo Sphere Infinio Ultra is available in 2 performance levels.

• Sphere Infinio Ultra 90 (Premium): As the premium version, the Phonak Audéo Sphere Infinio Ultra 90 includes all available features. It promises the highest level of comfort in loud and reverberant environments as well as in road noise. With Stereo Zoom, your hearing aid focuses on the voice of the person in front of you and largely tunes out background noise in loud surroundings. As a result, you enjoy optimal speech understanding.
• Sphere Infinio Ultra 70 (Advanced): A powerful option with some premium features at a more affordable price. It allows you to control audio playback via the buttons on the device. The Sphere Infinio Ultra 70 also delivers optimal speech understanding. Speech is captured in a 360° radius, the speaker's position is analyzed, and the sound is distributed to your ears accordingly.
