The short version
A capable, widely trusted brand when noise is the main challenge
If restaurants, meetings, and group conversations are where listening gets hardest, Phonak is one of the first brands we demonstrate. We fit the full lineup, so the recommendation is built around your hearing, your lifestyle, and your budget, not around what happens to be in stock.
Why Phonak
A brand engineered for the hard listening moments
Phonak is known for its AutoSense operating system, which reads the room and shifts programs automatically, and for its Roger microphone ecosystem, a practical option for hearing across distance and noise.
Dr. Aussem fits every major brand and verifies each fitting with Real Ear Measurement. The right brand depends on your hearing, your lifestyle, and your budget.
Legacy
A long track record in the field
Phonak has been developing hearing technology for decades. Its platforms are among the most widely fitted and serviced in both private practice and clinical settings around the world.
Noise
Built for difficult listening environments
AutoSense OS reads your surroundings and adjusts automatically. On the Audéo Sphere EON, a dedicated AI chip runs Spheric Speech Clarity in real time, separating speech from background noise as conditions change.
Range
A model for most losses
The EON platform covers mild through profound hearing loss, with Spheric Speech Clarity now available across three performance levels rather than only the top tiers. One brand can serve patients with very different ears and listening needs.
Ecosystem
Roger-ready from the box
RogerDirect is built directly into EON aids, so compatible Roger microphones connect without an external receiver. For anyone who needs to hear across a table, in a lecture hall, or over distance, that is a practical advantage.
The flagship
The Audéo Sphere EON, up close
The Audéo Sphere EON is Phonak's current flagship, and the model we most often demonstrate when noise performance is the main priority. It is the third generation of Phonak's Sphere technology, built around a dedicated AI chip that separates speech from background noise in real time, now in a design that is 25% smaller and 20% lighter than the previous generation.
Like every aid we fit, it is set and verified with Real Ear Measurement, so the sound is matched to your ear canal rather than left at the factory default. The EON adds WindBlock 2.0 for outdoor listening and upgraded automatic processing that keeps speech clarity active in more situations, which makes a meaningful difference in the places most aids struggle: busy restaurants, group conversations, and windy outdoor settings.
Day to day
Built for real days
The features people actually notice once the aids are in, plainly described. No spec sheet gymnastics.
Power
Rechargeable, more than all-day battery
Full-day battery on one charge, up to about 22 hours with demanding use. A full charge takes roughly 2.5 hours. An optional portable case with a built-in battery keeps power available for travel.
Connect
Broad Bluetooth with native Auracast
Streams calls and audio from phones, computers, tablets, and TVs, and works hands-free for calls and video. Native Auracast support connects to compatible public broadcasts in airports, theaters, and places of worship.
Noise
Speech isolated, wind managed
AutoSense OS reads the room and adjusts automatically, while a dedicated chip lifts voices and reduces background noise in real time. WindBlock 2.0 cuts wind noise outdoors while keeping speech clear, useful for walks, golf, and gardening.
Fit
Smaller, lighter RIC, verified to your ear
A receiver-in-canal style, 25% smaller and 20% lighter than the previous generation, in eight color options. Every fitting is verified with Real Ear Measurement so the sound matches your ear.
