What makes it special

Many things worth knowing about this hearing aid

Specs only tell you so much. Here's what's actually worth knowing about the Phonak Audéo Infinio Ultra Sphere I90 — what each feature does, and why it matters day to day.

🤖

ERA + DEEPSONIC (dual-chip) Chipset

The Audéo Sphere Infinio Ultra uses unique dual chip technology: the ERA chip plus the DEEPSONIC, a dedicated real-time AI sound processing chip Sonova International. This powers your Infinio Ultra Sphere I90 and I70.

📱

Bluetooth Connectivity

Connect straight to your phone, TV, and other devices — calls, music, and shows stream right into your ears. No extra remotes or accessories to carry around.

📡

Auracast Ready

Stream airport announcements, gym TVs, theater audio directly to your ears. The future is here.

🔋

56 hrs Battery Life

Two full days per charge. Weekend trips without the charger? Finally possible.

💧

1m Water Resistant

Rain, sweat, splashes. Golf in the rain? Go for it.

📱

Comfortable with smartphones Technology level

Higher tiers do more of the work for you — automatically taming background noise and adjusting to busy rooms so speech stays clear. Lower tiers cover the basics and lean more on manual adjustments.

❤️

Health Tracking

Monitors steps, balance, even respiratory rate. Your hearing aids just became a health coach.

🔋

Rechargeable Battery Type

Rechargeable, just like your phone. Set them in the case overnight and wake up to a full day of power — no tiny batteries to swap, fumble with, or keep buying.

⚕️

HSA / FSA Eligible

Hearing aids count as a qualified medical expense, so you can pay with pre-tax HSA or FSA dollars. Use your HSA/FSA card right at checkout, or file the receipt with your plan for reimbursement.

⚡

Recharging Case

The case carries its own battery, so it tops off your hearing aids two to three times before it ever needs an outlet. Just drop them in, close the lid, and charging starts on its own.

How ERA + DEEPSONIC (dual-chip) Works

53x More Processing Power

The DEEPSONIC chip exists for one job: dragging voices out of noise. It runs a deep neural network at 53 times the power of any previous Phonak chipset.
The Workhorse Chip

ERA handles Bluetooth, AutoSense, streaming, and everything non-AI. Splitting tasks across two chips means DEEPSONIC focuses on noise while ERA handles everything else.
Spheric Speech Clarity 2.0

Sphere's signature move, running on DEEPSONIC. Lifts voices out of chaos, sharpens clarity, and reassembles sound your brain trusts. Up to 3x more likely to catch every word.
AutoSense OS 7.0

The automatic operating system reads your environment 700 times per second. Calm room, loud bar, highway drive, concert. It picks the program. You just listen.

Spheric Speech Clarity

Follow Every Conversation—Even When Multiple People Are Talking

Remember the last family dinner where everyone was talking at once, dishes clattering, kids laughing in the background—and you just smiled and nodded, hoping you caught the important parts?

Those days are over. Spheric Speech Clarity 2.0 from the most powerful Phonak hearing aid separates voices from background noise automatically and instantly. It doesn't just turn down the noise—it actually identifies and focuses on the people speaking, whether they're beside you, across the table, or even behind you.

Life with Spheric Speech Clarity:

Hear clearly at restaurants without straining or asking people to repeat
Follow along when three conversations are happening at once
Come home from social events energized, not drained from listening effort
Stay at the dinner table laughing and chatting instead of retreating to quiet rooms

Built for the moments that matter most

Real situations the Phonak Audéo Infinio Ultra Sphere I90 is designed to handle effortlessly.

All-Day, Mixed Environments

Kitchen to car to coffee shop, your settings keep up automatically. No fiddling, no menus, just the right sound everywhere.

Noisy Restaurants

The clatter fades, the voice across the table comes forward. Order, laugh, and follow every word without leaning in.
One-on-One Conversations

Quiet moments deserve full attention. Catch every word from the person across from you, soft voices and all.
Outdoors

Walks, patios, the back nine. Wind and open air meet their match, so the outdoors stays calm, not gusty.
Phone and Video Calls

Workouts and Active Days

Sweat, motion, and weather are no problem. It stays put and keeps working while you do.

60 Day Trial

The Trial That's Actually Designed for How Hearing Aids Work

A hearing aid doesn't prove itself in a quiet room on a Tuesday afternoon. It proves itself at the family dinner where everyone talks at once. The restaurant with the acoustics that defeat every table in the place. The phone calls you've been avoiding for two years. The TV that's been creeping up in volume so gradually you didn't notice until someone pointed it out.

That's why our trial is 60 days, not a long weekend. You deserve to know these are right, not just right enough to keep because returning them felt complicated. So we made returning them not complicated.

Every purchase includes professional fitting by a licensed hearing care provider, unlimited adjustments throughout your trial, and devices that arrive calibrated for your specific audiogram. The trial isn't a safety net bolted onto the product. It's the whole philosophy.

Ready to start? Talk to our team. A real person picks up within two minutes, from 8 am to 9 pm Central weekdays and 8 am to 5 pm weekends.
