Description
Phonak Audéo Infinio Ultra Sphere is the premium AI hearing aid in the Infinio Ultra range, available in I90, I70, I50 and I30 performance levels.
The Audéo Infinio Sphere released in 2024 superseded Phonak’s Audéo Lumity Hearing Aids. The most recent upgrade to Ultra Sphere, in October 2025 brings even more improvements.
Phonak Audéo Infinio Ultra Sphere™ Rechargeable Hearing Aids – Overview
The Phonak Audéo Infinio Ultra Sphere is a top-of-the-line hearing aid designed for people who struggle to hear conversations in noisy places. It uses a special computer brain to separate the voices you want to hear from background noise. Here is what makes it stand out:
- Crystal-Clear Background Noise Filtering: It has a dedicated Artificial Intelligence (AI) chip that acts like a personal sound engineer. If you are in a crowded restaurant, it aggressively blocks out clattering plates and background murmurs while pulling the voices of the people around you into focus.
- Hears Voices from Any Angle: Instead of only amplifying sounds directly in front of you, it captures voices clearly from any direction.
- Exceptional Battery Life: You can wear it all day and night. It lasts up to 56 hours on a single charge.
- Easy to Connect: It links up wirelessly to almost any Bluetooth device. You can easily take phone calls hands-free or listen to your favorite TV shows directly through the hearing aids.
- Low Maintenance: It uses special protective tips called EasyGuard domes. These are designed to keep out earwax, which means less cleaning.
- Comfortable Size: While it is slightly larger than some older models to fit the extra AI chips, the Ultra Sphere sits comfortably behind the ear and is lightweight.

Design and Build of Audéo Sphere Infinio
The Phonak Audéo Sphere Infinio is designed to deliver a comfortable, discreet listening experience. The hearing aid features a compact design, making it easy to wear and use. The Phonak Audéo Sphere Infinio is also built with durability in mind, featuring advanced waterproofing and a robust design that can withstand everyday wear and tear. With its ergonomic design and advanced features, the Phonak Audéo Sphere Infinio is an ideal choice for individuals seeking a high-quality hearing aid that delivers exceptional, consistent audio and improved hearing performance.
New Technology with a dedicated AI chip
All Infinio hearing aids include the new ERA Chip, which has improved processing power, allowing for four key new features:
- APD 3.0 – a new fitting prescription that uses the latest research and ERA processing speed to give the user the correct gain at each hearing loss frequency.
- AutoSense 6.0—Trained with artificial intelligence, AutoSense is software that automatically changes the hearing aid’s programs and settings. As a hearing aid user moves between different listening environments, Autosense automatically selects the best program, adjusts the volume, and adjusts the hearing device’s advanced features.
- Enhanced Bluetooth – Universal connectivity and 2-way streaming to any Bluetooth devices, including phones, tablets and laptops. Phonak Infinio hearing aids will pair up to 8 and 2 Bluetooth devices simultaneously. The new ERA chip increases Bluetooth transmission power, enabling users to maintain a high-quality signal over twice the distance of the previous Phonak Bluetooth.
- Auracast Ready – Auracast™ broadcast will enable devices such as smartphones, laptops, televisions, or public address systems to broadcast audio to an unlimited number of nearby compatible receivers, including hearing aids, speakers and earbuds.
The new DEEPSONIC dedicated AI chip enables the new Spheric Speech Clarity system to operate. Phonak Sphere Infinio hearing aids are Phonak’s first hearing aids that can fully exploit the power of Artificial Intelligence (AI) for instant speech separation from Noise. They have been trained using 22 million sound samples using a Deep Neural Network (DNN), and the Spheric Speech Clarity system can use these learnings to identify and separate unwanted noise from the speech signal. This enhanced signal-to-noise ratio results in improved speech understanding in noisy environments. Phonak claims that spheric speech clarity delivers unprecedented clarity and doubles your chances of clean, clear speech in complex listening situations.
Motion and Background Noise Technology for Better Hearing
Speech Enhancer is an adaptive feature that enhances a soft speech signal in quiet situations. Hearing aid wearers experience reduced listening effort in quiet.
- Automatically activates when soft speech is detected
- Specifically, it targets soft and distant speech in a quiet environment
Dynamic Noise Cancellation: This noise-reduction feature helps remove unwanted noise and reduces listening effort in background noise. The system works with Phonak’s adaptive beamformer and the motion sensor.
- Dynamic Noise Cancellation works with directional microphones to make it easier to hear in noisy environments.
- Motion Sensor Hearing detects when the wearer is moving to optimise hearing in noise.
- SpeechSensor detects the primary speech source and automatically adjusts the microphone mode to ensure better access to speech from the sides and back.
- This feature is particularly effective in the noisiest environments, ensuring clear communication.
Motion Sensor: This detects whether the user is stationary or moving and how noisy the surroundings are. AutoSense OS™ 6.0 automatically adjusts the hearing aid setting to ensure optimal hearing.
StereoZoom 2.0: This feature enables the hearing aid microphones to focus on speech from the front and is activated in noisy listening environments.
With SpeechSensor: Users can hear from the back and the sides. This automatic feature detects the primary speech source and adjusts the microphone modes to ensure the client has better access to speech from the sides and back.
Phonak also offers remote assistance, allowing audiologists to adjust and fine-tune hearing aids based on customer needs, ensuring personalised service and ongoing support.
Phonak Infinio Hearing Aid Colours
Infinio hearing aids are available in velvet black, silver grey, sienna red, sand beige, sandalwood, graphite grey, copper, chestnut, champagne, Atlantic green, and beige.
Difference in Infinio Ultra Sphere Performance Levels
Phonak Audeo Infinio Ultra Sphere Hearing Aids are available in 2 technology levels:
- Premium – 90
- Advanced – 70
The performance levels are the same size and use the ERA and DeepSonic chip. The difference is that the software loaded on the device — the Advanced 70 model — has no speech enhancer. Your audiologist can help you choose the correct technology level. You should consider your hearing loss, the listening environments you encounter, and your budget. Choosing the right technology level is crucial for maintaining optimal hearing health.
