Phonak EON delivers the proven speech-in-noise performance of Sphere in a hearing aid that is 25% smaller and 20% lighter, with upgraded automatic processing, advanced wind-noise reduction, and native Auracast connectivity.

At La Cañada Hearing Aids & Audiology in La Cañada Flintridge, CA, we're proud to offer Phonak EON, the third generation of Phonak's Audéo Sphere platform. EON delivers the proven speech-in-noise performance Phonak is known for in a smaller, lighter design, with upgraded automatic processing and native Auracast connectivity. Dr. Kevin Ivory provides expert fitting and ongoing care to help you get the most from this advanced hearing solution.
At the heart of Phonak EON is Spheric Speech Clarity 3.0, which uses dedicated AI processing to separate speech from background noise, enhance the speech signal, and reintegrate it for clearer listening in difficult environments. In Phonak testing, the platform offers up to 50% better speech understanding compared with advanced directional microphone technology, up to 37% less listening effort, and makes users up to two times more likely to understand speech coming from any direction.
Notably, Spheric Speech Clarity is now available across three performance levels rather than only the top two, giving more patients access to this technology at different price points.
Phonak EON brings Sphere performance into a more comfortable, discreet form factor:
EON features AutoSense OS AI 8.0 and APD 4.0, designed to react more quickly and intelligently as your listening environment changes. The goal is to preserve clarity and sound quality without requiring you to manually change programs. The system adapts faster between quiet and noisy environments, improves signal-to-noise ratio during sudden changes, and keeps Spheric Speech Clarity active in more situations than before.
If you spend time outdoors, WindBlock 2.0 reduces microphone turbulence while preserving access to speech and environmental sound. It offers up to 50 dB of wind-noise reduction while preserving up to 30 dB of signal-to-noise ratio benefit. In Phonak testing, more than 90% of participants preferred WindBlock 2.0 for naturalness, and the feature is available across all performance levels.
The Era connectivity chip supports broad Bluetooth compatibility and allows the hearing aids to function as a hands-free headset for calls and video conferencing:
Phonak EON provides more than all-day battery performance, with up to approximately 22 hours even with demanding use that includes streaming and time in noisy environments. The hearing aids charge from 0% to 100% in approximately 2.5 hours, and an optional portable charging case with its own built-in battery keeps you powered when you're away from home.
Phonak EON is available in several configurations to support hearing losses ranging from mild through profound:
Phonak EON is often an excellent match for people who struggle to understand speech in restaurants and other noisy places, who attend meetings and social gatherings, who spend significant time outdoors, or who stream calls, music, and television throughout the day. It's also well suited to those who want a smaller Phonak Sphere hearing aid with native Auracast capability, including CROS candidates.
