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 R Infinio Ultra I70 — what each feature does, and why it matters day to day.

🤖

ERA (single chip) Chipset

Phonak's ERA chip is Auracast ready and offers an extended connectivity range.

📱

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.

🔋

31 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.

📱

Advanced 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.
