Smaller than ever. Powerful beyond belief. EON Sphere maintains all-day performance, enabled by 37%  greater efficiency from a new chip and a re-trained DNN.

Powered by Spheric Speech Clarity™ 3.0: Measured in challenging listening conditions, Spheric Speech in Loud Noise achieves up to a 10dB SNR benefit.1

Proven to outperform four other hearing aids in SNR improvements in realistic test set-ups.1

Clarity that moves with you, automatically

EON Sphere hearing aids exclusively feature Spheric Speech Clarity™ 3.0, powered by the new HYPERSONIC™ chip. Spheric Speech Clarity 3.0 separates speech from noise in real time, for conversations that instantly stand out from the noise.

Backed by Phonak AI and made for living, they offer our most natural sound available³. The smaller, comfortable design is powerful beyond belief and redefines what a hearing aid can do for your patients.

AutoSense OS™ AI 8.0

AI precision. An even more natural listening experience4

  • Hearing that keeps up: AutoSense OS™ AI 8.0 automatically adapts as patients move through their day, selecting programs and features like Speech in Loud Noise and WindBlock 2.0, helping them transition seamlessly between different listening situations. Enhanced processing supports a more nuanced activation of Spheric Speech Clarity 3.0, helping improve speech understanding and reduce listening effort.3
  • Improved listening experience during changing noise levels: AutoSense OS AI 8.0 introduces a new exit criterion for Spheric Speech in Loud Noise, meaning patients benefit from Spheric Speech Clarity longer. It helps create a more consistent listening experience when noise levels fluctuate. For example, when people move, join or leave groups, or different conversational partners speak.
  • Optimized compression for more natural sound:
    Adaptive Phonak Digital 4.0 fitting formula now delivers even higher fidelity sound. Newly refined compression parameters provide the optimal compression approach when there are sudden changes in the listening environment. Patients experience an even more natural listening experience.4
 

Our most natural sound available

The new WindBlock 2.0 reduces wind noise by up to 50 dB and provides a more natural listening experience.⁵ Study subjects overwhelmingly preferred the sound quality, listening comfort, listening effort, naturalness and speech clarity.⁵
