Phonak Audéo EON Sphere

Phonak Audéo EON Sphere – Next-Generation AI Hearing Technology

The Phonak Audéo EON Sphere sets a new standard for AI-powered hearing. As the evolution of the Infinio Sphere series, the EON Sphere combines maximum speech clarity in extreme noise with a significantly more compact, lighter form factor and extended battery life. Two specialized processors—the newly developed HYPERSONIC™ AI chip and the ERA chip—separate speech precisely from disruptive background noise in real time, from any direction.

Key Upgrades & Core Innovations

• Significantly Smaller & Lighter: The casing is 25% smaller, 20% lighter, and—thanks to the HYPERSONIC™ AI chip—37% more energy-efficient than the previous Sphere generation.

• Spheric Speech Clarity 3.0: Delivers up to a 10 dB improvement in Signal-to-Noise Ratio (SNR) and increases speech understanding in loud environments by up to 44%. Voices are understood up to twice as well from all directions.

• AutoSense OS™ AI 8.0: The AI operating system analyzes the acoustic environment up to 700 times per second, seamlessly adjusting amplification and noise cancellation.

• WindBlock 2.0: Reduces disruptive wind noise by up to 50 dB and improves outdoor SNR by up to 30 dB for a natural soundscape.

• Speech Enhancer & APD 4.0: Reduces perceived listening effort by up to 45% and end-of-day fatigue by 21%.

• EasyGuard™ Domes: The new, sealed wax guard system simplifies maintenance and reduces upkeep effort by up to 38%.

Future-Proof Connectivity & Auracast™ The Audéo EON Sphere offers universal Bluetooth connectivity (Phonak Made for All) for hands-free calling, audio streaming, and connection to the myPhonak app. It also supports Auracast™ Broadcast Audio with a range of up to 692 feet (211 meters). Using the built-in QR code scanner in the myPhonak app, users can tune directly into public audio broadcasts in places like theaters, museums, or gyms.

All-Day Battery Life Despite the massive processing power of the dual AI chips, the Audéo EON Sphere delivers up to 38 hours of battery life per charge. Users can choose between the compact Charger RIC E or the portable ChargerGo RIC I EON with an integrated power bank.
