The New Phonak Audéo Sphere Infinio: Cutting-Edge Innovation and Unmatched Hearing Comfort

The Phonak Audéo Sphere Infinio is the latest hearing aid from Phonak and sets new standards in hearing acoustics. Launched in summer 2024, it impresses with state-of-the-art audio technology and innovative features such as the ERAM chip and DeepSonic AI technology.

This article explains what makes the Phonak Sphere Infinio better than its predecessor Phonak Lumity and lists its features, benefits and technical highlights. It further explains why this sophisticated hearing aid is the ideal choice for people looking for a natural and clear hearing experience.

The innovations behind the Phonak Sphere Infinio

Phonak's goal is to create a natural hearing experience while at the same time making everyday communication as easy as possible. With the help of artificial intelligence (AI), a specially developed microchip and state-of-the-art audio technology, the Phonak Audéo Sphere Infinio strives to perfectly blend these two goals.

✓ Automatic adaption of hearing settings to environment
The Sphere Infinio adapts to the environment in real time. Whether you are in a noisy restaurant, having a conversation outdoors or sit in a quiet room, the hearing aid automatically optimizes the sound settings to provide the best possible listening experience.

✓ 360-degree sound perception
Thanks to the new Sphere technology, the hearing range is extended in all directions. The Sphere Infinio removes unwanted noise and filters out speech as purely and clearly as no other technology has been able to do before. This enables exceptional speech clarity.

✓ Seamless connectivity
The Phonak Audéo Sphere Infinio can be connected to up to eight smartphones, tablets and other Bluetooth devices, including two devices simultaneously. It supports Bluetooth Classic as well as the new Auracast wireless connection technology, which will become increasingly important in the coming years. This offers more stable connections and a greater range - an advantage over previous models.

✓ Waterproof
The Phonak Audéo Sphere Infinio is built for active lifestyles. It meets the IP68 standard, making it resistant to dust and water, as well as moisture, sweat, and various weather conditions. This makes it perfect for people with active and busy lives who want an uncompromising hearing experience, no matter their surroundings.

✓ 16 hours of battery life, incl. 4 hours of streaming
✓ Portable and rechargeable charging station with capacity for multiple charge cycles

Two microchips for outstanding performance

At the heart of the Phonak Sphere Infinio are the two new chips: the ERAM chip and the DeepSonic chip. Both contribute significantly to improved sound processing and user experience.

ERAM chip: More computing power for faster sound processing
The ERAM chip is the powerhouse behind the fast and precise signal processing of the Sphere Infinio. It has more RAM memory, which enables finer sound processing in real time. This additional processing power results in a noticeably faster adaptation of the hearing aid to different acoustic situations. For example, if you move from a quiet room to a lively environment, the ERAM chip ensures that the hearing aid immediately adjusts to the new surroundings. This allows users to always enjoy a comfortable and natural sound.

DeepSonic chip: Intelligent separation of speech and background noise
The DeepSonic chip is another decisive factor for the sound quality of the Sphere Infinio. It is specifically responsible for processing speech and uses artificial intelligence (AI) to differentiate between speech and disturbing background noise. The chip's AI has been trained with over 22 million sound samples to precisely recognize and amplify speech while reducing distracting noises. This leads to an improvement in the signal-to-noise ratio (SNR) of up to 10 dB, which is particularly beneficial in noisy environments such as restaurants or at events.

For techies: The DeepSonic chip constantly analyzes ambient environments at over 1,000 times per second. Using deep learning models trained on millions of real-world soundscapes, the chip identifies over 50 distinct acoustic scenes, such as: café chatter, urban traffic, windy environments, and multi-speaker conference rooms. Further, to isolate a user’s desired conversation partner, the system adjusts dynamically based on head movement, gaze direction (when paired with smart glasses), and even biometric feedback like heart rate variability. Rather than apply uniform gain across frequencies, the DeepSonic chip uses adaptive gain layering. This means it boosts clarity of speech while reducing energy in frequency bands dominated by unwanted noise—resulting in less listener fatigue.

How the Sphere Infinio Outshines Previous Models

Phonak Audéo Sphere Infinio vs Phonak Audéo Lumity: Compared to its predecessor Phonak Lumity, the Phonak Sphere Infinio has a number of improvements thanks to the new chips:

More computing power for faster sound processing 
The ERAM chip enables faster processing of sounds, which allows the hearing aid to switch between different sound environments almost instantaneously. This was not yet possible with such precision with the Audéo Lumity and represents a real advance in the dynamic fitting of the hearing aid.

Better speech clarity thanks to the DeepSonic chip
The DeepSonic chip improves speech clarity thanks to its ability to amplify voices depending on direction and to filter out disturbing noises. While the Lumity model already offered good differentiation between speech and background noise, the Sphere Infinio achieves significantly finer separation thanks to the new AI technology - even in particularly challenging acoustic environments.

Improved Bluetooth connection
The signal strength and range of the Bluetooth connection has been improved with the Sphere Infinio. This means that you can move further away from the signal source (such as your smartphone or tablet) without losing the connection. This is a noticeable advantage compared to the Audéo Lumity and provides more flexibility in everyday life.

Who is the Phonak Audéo Sphere Infinio for?

The Phonak Sphere Infinio isn’t just a new hearing aid; it’s a preview of the future of wearable computing. With on-board AI, real-time environmental modeling, and a user-centric design, it blurs the line between assistive technology and augmented hearing. Phonak has once again proven that better hearing is not just about amplification—it’s about understanding.

The Phonak Audéo Sphere Infinio is the ideal choice for people looking for a modern and intelligent hearing solution. It not only offers excellent sound quality, but also scores points for ease of use and the ability to automatically adapt to different environments. The two new microchips - the ERAM chip for fast sound processing and the DeepSonic chip for optimized speech understanding - provide a hearing experience that is noticeably different from its predecessor.

With the launch of the Sphere Infinio, we are entering a new era where hearing aids do more than help people hear—they help them thrive in the complexity of real-world environments. If you are looking for a hearing aid that offers you the best hearing experience in all situations, the Phonak Audéo Sphere Infinio is one of the top choices.
