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.

📱

Premium 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.

🔋

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 follow the full conversation.
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.

Frequently Asked Questions

What does the DEEPSONIC chip actually do?

No. Splitting the workload actually improves efficiency. Each chip runs only its designated tasks instead of one chip multitasking everything at once.

What's the real-world battery life?

The Phonak Audéo Infinio Ultra Sphere I90 delivers 56hours, assuming 3 hours of daily Bluetooth streaming. This typically means 2+ full days of use before recharging.

With great surprise!!
I love my i90 infinio spheres. My tv sound is much lower than before I had them. I can hear my sister who speaks softly. I used to say “what?” all of the time. The price can’t be beat. My other sister bough the same hearing aids for $6500. I can’t wait to put them on in the morning. Sometimes I forget they’re in my ears and hop in bed with them in.

Exceeding Expectations.
The aids are a cinch to get working and hold a charge all day. They are comfortable. My audiologist consult with the company solved a problem. Their inbuilt ability to switch from, say, a TV to a conversation or a podcast is magical. No buttons to hit. It just happens! The clarity is good. I have severe hearing loss so complete restoration is not possible.

phonak experience so for
Just on my own,W.O. tec imput yet, I have been able to make my new Phonaks funtional. For the most part, they seem slightly easier to use than my older Oticons. I still have difficulties,especially w/my Right ear w/fit and transient background noise in my truck and around people in restaurants etc (tinnitus hasn't been as big a factor yet,I'm curious to see if this helps that in the future ) I find it hard to see any noticeable adjustmens in tone and sound as I buzz down the list of TV,RESTAURANTS,AUTOMATIC...etc (?) .............. Curious why that is ?! ) I remain hopeful we will work out the bugs and I will soon be a better 'operator' after a little instruction and practice. I look forward to our upcoming review/instructional session w/ Michael / Today at 10:00am . Thanks for checking in !! LLB

Thank you for sharing your experience with the Phonak Audéo Infinio Ultra Sphere I90, Larry. We're glad to hear that you've been able to get them functional on your own and that you're finding them slightly easier to use than your previous Oticons — that's a great start.

We completely understand your concerns about the fit on your right ear and the challenges you're experiencing with background noise in your truck and around restaurants. Those are important factors that definitely affect your listening experience. We also hear you on your curiosity about the adjustments across the different settings like TV, Restaurants, and Automatic — it's natural to want to notice clear differences as you work through those options.

We're really glad you're looking forward to working with Michael on your review and instructional appointment — that hands-on guidance and practice can make a real difference in helping you become more comfortable with your devices and getting the most out of them.
