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.

Frequently Asked Questions

Is the ERA chip different from older Phonak chips?

Yes. ERA is a complete redesign with 74% more RAM and faster processing than the previous PRISM chip.

Which Phonak models use the single ERA chip?

The Phonak Audeo Infinio R and the CROS Infinio both run the single ERA chip. Sphere Ultra adds a second DEEPSONIC chip on top of ERA.

Does the ERA chip support Auracast?

ERA is LE Audio and Auracast ready. A future firmware update will activate Auracast as venue broadcasting rolls out worldwide.

What's the real-world battery life?

The Phonak Audéo R Infinio Ultra I90 delivers 31hours, 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.

Ready to Experience ERA (single chip)

Try Phonak Audéo R Infinio Ultra I90 risk-free with our 60-day money back guarantee. Free shipping, free returns, free audiologist support.
