The Phonak Audéo EON Sphere 70 combines advanced AI-powered hearing technology with a rechargeable Receiver-in-Canal (RIC) design. Built around Phonak's HYPERSONIC chip and Spheric Speech Clarity 3.0, it is designed to help users follow conversations more comfortably, particularly in challenging listening environments.

The hearing aid uses AI-powered processing to analyze and process sound in real time. Its Spheric Speech Clarity 3.0 technology is designed to help distinguish speech from surrounding noise, while AutoSense OS AI 8.0 automatically adapts hearing settings according to the listening environment.

Audéo EON Sphere 70 also provides universal Bluetooth connectivity, allowing compatible devices such as smartphones, tablets and computers to connect for calls and audio streaming. With Auracast broadcast audio, compatible users can also access supported broadcast audio in public spaces such as theaters, museums, gyms and conference venues.

For additional listening support, the hearing aids are Roger ready, allowing compatibility with Roger solutions. WindBlock 2.0 helps manage the effects of wind noise, while the rechargeable design provides convenient everyday use.

Phonak states that Audéo EON hearing aids can provide up to 38 hours of battery life, depending on the hearing aid configuration and usage conditions. The result is a combination of advanced sound processing, wireless connectivity, rechargeable convenience and a discreet RIC form factor.
