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. Swipe 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.

  • Callout 1 processing power

    53x More Processing Power

  • Callout 2 workhorse chip

    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.

  • Callout 3 speech clarity

    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.

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

Have questions about the process?

Talk to a real hearing specialist — no sales pitch.

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

  • Group of four friends gathered around a table, smiling and interacting in a meeting.

    Varied Hearing Environments

    For people with exciting and varied social calendars. Three dinners a week, a wedding next month, a kid's birthday party in between. Auto-switching keeps up so you don't have to think about which program you're in. Just keep moving.
  • Golfer in action on a golf course with trees and clouds in the background

    Windy Outdoors

    Golf, walks, patios, porches. Wind noise gets filtered out. The conversation makes it through.
  • Person taking a photo of a concert with a smartphone, surrounded by colorful lights.

    Concerts, Theaters, Airports

    Auracast beams venue audio directly to your ears. No lag, no missed announcements, no pretending you heard the gate change.
  • Smart TV displaying various app icons in a dark room

    TV Without the Volume War

    Dialogue streams straight to your ears at your volume. Your spouse keeps theirs. Marriage intact.
  • friendly office worker woman taking an order for affordable hearing aids

    Phone Calls in Both Ears

    Hands-free, studio-quality, zero repeats. Every word, both ears, no "hold on, let me switch sides."
  • Friends hold sparklers while watching winter fireworks.

    Big Crowds and Major Events

    Stadium games, festival weekends, packed weddings, conference floors. Auracast pulls venue audio straight to your ears, and the AI keeps voices intact when the room is at full chaos.
  • An unhappy man sits at his desk at work.

    Long Workdays in Varied Spaces

    Coffee at 8, meeting at 10, lunch out at noon, calls until 5. Different rooms, different noise levels, different streaming sources. The battery holds. The chip keeps up. You don't notice the hearing aids — you notice you're not tired.
  • Older people do yoga outside.

    Workouts and Outdoor Sports

    Joggers, golfers, gym regulars, weekend hikers. Motion sensors track what you're doing and adjust on the fly. The IP68 rating handles sweat, drizzle, and the time you forgot to take them out for a shower.

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.

If after 60 days they're not right, wrong model, wrong fit, or just wrong time, return them for a full refund. No restocking fees. No store credit. No "have you tried adjusting the volume." No explanation required.

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.
