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.

Exoerience was great
I received the hearing aids and they were good but needed a little tweaking for clarity.
They had already contacted me and had set up tweaking for the next week which has come and gone and everything went great. So far so good.

They alllow me to hear and understand spoken words.
These devices work in real time to adapt to my changing environment. I am hearing sounds I haven't in years even though I was paying for top rated hearing aids before. I do not have the words that can express the positive improvement in my hearing and word recognition.
