Full product details

Restaurants and group conversations are where most hearing aids give up. The new Phonak Audéo EON Sphere E90 tops Phonak's EON line, and it centers on a dedicated speech-processing chip. Phonak rates it for Spheric Speech Clarity 3.0 at its highest strength, and it switches on automatically. It adds Speech Enhancer and StereoZoom 2.0, and Phonak states up to 38 hours of battery life. Our licensed hearing care providers program it to your audiogram before it ships.

Frequently Asked Questions

What's the real-world battery life?

The Phonak Audéo EON E90 Sphere delivers 38hours, 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.

No more "what did you say?"
I love these hearing aids. Background noise is much less, my husband is happy I can hear him (almost too much as I can hear his mutters). Going out with people is now pleasurable as I can hear them with background noise much diminished. It's just a pleasure to hear well again. My old cheap ones didn't help me like this.
