Full product details

Noisy restaurants are where conventional hearing aids struggle, because turning up the room turns up the clatter along with the voice across the table. The Phonak Audéo Infinio Ultra Sphere I90 adds a second chip that Phonak says separates speech from noise in real time. That brings the voice forward while the room drops back. At the I90 level, Spheric Speech Clarity runs at full strength. The I90 also carries Speech Enhancer, which lifts soft voices in quiet rooms. Infinio Ultra is the generation before EON, the established version of Phonak's Sphere technology. Licensed hearing care providers program it remotely before it ships.

Frequently Asked Questions

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.

What is the 60 Day Risk-free Trial?

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.

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.
