Phonak Audeo EON Sphere 90
The Phonak EON Sphere 90 delivers Premium performance by FitHearing standards. Premium technology will utilize the most channels and include all functions within the EON platform making these devices ideal for those with active lifestyles.
The second chip in the EON Sphere 90, comparable to the former generation Infinio Ultra, mimics our natural neural network in our brain and brings greater speech clarity. More processing and battery life is actually housed in a smaller casing, making the EON Sphere more comfortable and discreet than its predecessor while delivery greater performance from the HYPERSONIC AI chip, AutoSense 8.0 and Spheric Speech Clarity 3.0.
With AutoSense 8.0 your EON Sphere 90 hearing aids will learn and adapt while you wear them and provide additional processing with the enhanced software and industry leading AI chip. Additionally, they include WindBlock 2.0, which improves clarity and adaptability within outdoor and specifically windy conditions.
We recommend the Audeo EON Sphere 90 level over the EON Sphere 70 due to its use of the full strength SpeechSensor rather than the medium strength. The Phonak EON Sphere 90 includes the Speech in Loud Noise function for clarity in any environment, including busy social gatherings, outdoor activities, restaurants and concerts. If you enjoy noisy outings such as these, the Phonak Audeo EON Sphere 90s may be the hearing aids for you.
EON Sphere 90s feature traditional Receiver-in-canal (RIC) form factor, whereby the hearing aids sit comfortably and discreetly behind your ear. Audeo EON Sphere 90s are rechargeable, so simply place them on the charger each night, and they will be ready to go with you all day.
