STÄFA, Switzerland, Aug. 24, 2026 (GLOBE NEWSWIRE) -- Phonak today launched EON, its next-generation hearing aid platform. Powered by the newly developed HYPERSONIC™ chip, EON combines Spheric Speech Clarity 3.0, AutoSense OS™ AI 8.0 and Made-For-All connectivity in one, more efficient platform. It further strengthens Phonak’s competitive position in improving speech understanding in noise, automatically adapting to the surrounding sound environment and connecting to virtually any Bluetooth® enabled device. EON is 25% smaller and 20% lighter than the previous Sphere generation, while offering up to 38 hours of battery life. *
“EON sets a new benchmark for intelligent hearing. It brings together the capabilities that matter most in daily life: understanding speech, adapting automatically and staying connected with confidence,” said Josipa Kern, Global Head of Phonak.
Scene intelligence meets speech clarity: EON is Phonak’s 3rd generation of real-time AI
EON brings together two complementary AI systems: Spheric Speech Clarity 3.0 and AutoSense OS™ AI 8.0. Both work in parallel and real time to make hearing more adaptive, precise and to help people hear better across changing listening situations.
Spheric Speech Clarity 3.0 uses deep neural network processing to separate speech from background noise in real time, making users twice as likely to understand every word from any direction.1
In parallel, AutoSense OS™ AI 8.0 continuously analyses the surrounding sound environment and automatically activates the optimal combination of features for each situation, supporting a more natural listening experience in speech-in-loud-noise situations compared with previous generations.2
Designed for real life, indoors and outdoors
EON also introduces WindBlock 2.0, which automatically reduces wind noise by up to 50 dB and can improve the signal-to-noise ratio by up to 30 dB.3 It supports clearer conversations and a more natural listening experience outdoors.
All day user confidence powered by a new chip
Thanks to the new HYPERSONIC™ chip powering Spheric Speech Clarity 3.0, EON uses 37% less power than the previous generation while maintaining advanced real-time AI performance. This efficiency improvement allows the hearing aid to be 25% smaller and 20% lighter, without compromising on all-day wearability.
EON delivers up to 38 hours of battery life on a single charge. Available in eight colour options, EON comes with two new charging solutions, including a portable charger with an integrated battery for added flexibility on the go.
“With the HYPERSONIC™ chip, we have engineered a significant step forward in power efficiency without compromising real-time AI performance. This allows EON to deliver advanced speech processing in a smaller, lighter design while supporting the all-day reliability people expect from Phonak,” said Anders Rosengren, Chief R&D Officer, Sonova.
Made-For-All connectivity
EON offers the most comprehensive connectivity in the market. It means it works with virtually any Bluetooth® enabled device and combines Bluetooth Classic, Roger Direct™ and Auracast™ broadcast audio into one hearing aid. Wearers can access calls, streaming, wireless microphones and compatible public audio broadcasts in venues such as museums, theatres and airports.
Stress-testing EON: a real-world experience in the Arctic
Dr. Amanda Klekowski von Koppenfels, a scholar, researcher and educator living with hearing loss, was the first person outside Phonak to wear and test EON during an Arctic expedition. She said: “Hearing aids aren’t limiting, they are empowering. In unforgiving Arctic conditions, I was able to hear a crack in the packed snow beneath us and follow conversations clearly over the sound of crunching snow. EON's WindBlock performed remarkably well, even as the wind whipped around us and made the tents flap. Despite wearing as many as four layers of hats and cold-weather gear, I could hear so clearly that, at times, other members of the expedition without hearing loss were asking me to repeat what had been said, rather than the other way around.”
Phonak EON will be available to order by licensed hearing care professionals in the United States as of August 24, 2026, with additional markets, including Germany, France, the United Kingdom, Australia and others, to follow in September.
