The Phonak Sphere Infinio hearing aid blends artificial intelligence, smart features, and exceptional sound clarity. It’s built for people who want effortless conversations—even in noisy environments.
This hearing aid includes dual processing chips, Bluetooth 5.3, and breakthrough Spheric Speech Clarity. It even adapts automatically to sound environments. If you’ve struggled with background noise before, this device could change everything.
Let’s explore the reasons to consider this cutting-edge hearing aid—and how it helps you hear more clearly, comfortably, and confidently.

1. Unmatched Sound Clarity with DEEPSONIC™ AI Chip
The Sphere Infinio contains two powerful chips: Phonak’s ERA™ and the groundbreaking DEEPSONIC™ AI processor.
DEEPSONIC™ performs over 7700 million operations per second using 22 million real-world sound samples. It’s 53 times faster than older chips and separates speech from noise with stunning accuracy.
This chip powers Spheric Speech Clarity, which gives you a huge boost in real-world understanding. According to Phonak’s field study, this feature can double your ability to understand speech in noisy environments.
Imagine being in a loud restaurant or at a busy family party and still hearing every word. The Sphere Infinio makes that possible.

2. StereoZoom 2.0 Gives You Control in Chaos
StereoZoom 2.0 narrows your listening focus, helping you hear a single voice in a noisy room.
You can fine-tune this focus in real time using the myPhonak app, giving you more control. Whether you’re at a dinner party or a business meeting, you decide what you want to hear.
This technology dramatically reduces unwanted noise without muting your surroundings. It adapts quickly, adjusts seamlessly, and helps you stay engaged during conversations that matter.
You no longer have to nod politely and guess what someone just said.
3. Autosense 6.0 Adjusts Automatically, So You Don’t Have To
Think of AutoSense 6.0 as a smart operating system that constantly monitors your soundscape.
It automatically switches settings based on your environment—without you lifting a finger. At a concert? It adjusts for music. In a car? It reduces road noise and enhances conversation. In a café? It tunes background chatter down while amplifying nearby voices.
It includes:
- Echo Reduction for hard surfaces and large rooms
- Noise Adaptation for bustling environments
- Music Optimization for rich, balanced sound
- Directional Focus to follow voices in moving vehicles
- Natural Sound Tuning for serene, quiet settings
You get great sound wherever you are, without needing to fiddle with settings.

4. Built Tough for Life’s Messy Moments
The Sphere Infinio I90 model has an IP68 rating, meaning it’s water, sweat, and dust resistant.
You don’t have to worry about rain, moisture, or grit from outdoor activities. Whether you’re gardening, biking, or walking in the rain, this hearing aid keeps performing.
That resilience means more reliability, less stress, and fewer repair visits.
5. Seamless Connectivity with Bluetooth 5.3 Dual-Mode
The Sphere Infinio features Bluetooth 5.3 Dual-Mode, offering smoother, more stable streaming.
It connects with up to 8 devices and streams from 2 devices at once. Watch TV while answering a call or stream from your tablet and phone simultaneously.
The Sphere also works with:
- Roger Microphones for group conversations
- PartnerMic for face-to-face chats
- TV Connector for direct audio from your television
No clunky accessories, no lag—just fast, reliable connections and better sound.
6. Smart Control in the Palm of Your Hand
Sphere Infinio makes everyday listening effortless with Tap Control and the myPhonak app.
Just double-tap your hearing aid to:
- Answer or end phone calls
- Activate your voice assistant (like Alexa or Siri)
- Pause, play, or switch streaming sources
The myPhonak app lets you:
- Adjust volume and programs
- Save personal listening settings
- View battery status
- Track activity data like steps
- Request remote support from your hearing care provider
You get advanced features without confusing buttons or settings.
7. Real Tinnitus Relief and Extended Battery Life
Many people experience tinnitus—constant ringing or buzzing in the ears. Tinnitus Balance in Sphere Infinio offers relief.
This built-in sound therapy plays calming tones that reduce your awareness of tinnitus. It works quietly in the background, helping you stay focused and relaxed.
On top of that, battery life stands out. Users report up to 32 hours on a single charge. If you’re low on time, a 15-minute quick charge gives hours of use.
No more frequent charging. No more worrying if your hearing aid will last the day.
What Better Speech Recognition Means for Your Life
The Sphere Infinio doesn’t just make sound louder—it helps your brain understand it better.
That’s the power of improved speech recognition, especially in noisy places. With Sphere Infinio, you:
- Feel less exhausted at the end of the day
- Avoid the stress of mishearing someone important
- Stay more confident in group settings
- Reconnect with family and friends without frustration
In Phonak’s testing, users experienced:
- 34% less listening effort when hearing speech from a distance
- 45% less effort hearing speech from an adjacent room
- Up to 36.7% better speech understanding than other top devices
These improvements go beyond hearing—they enhance your overall well-being and quality of life.
