Phonak Audéo Infinio Sphere / Sphere Ultra Hearing Aids

Phonak Audéo Infinio Sphere / Sphere Ultra Hearing Aids

The Phonak Audéo Infinio Sphere is Phonak's most advanced hearing aid, built for people who regularly struggle to hear in noise, group conversations, and busy environments. The Sphere Ultra adds dedicated AI hardware that takes speech clarity a step further. Both models are available here with licensed audiologist support and genuine manufacturer pricing.

Key Technology

• DEEPSONIC AI Chip: Hardware-level noise reduction and speech enhancement delivering up to 10dB better signal-to-noise ratio. Trained on over 22 million real-world sounds and capable of 7.7 billion operations per second
• Spheric Noise Cancellation: Filters noise from any direction in real time, reducing listening effort by up to 45% according to independent Phonak research
• AutoSense OS 6.0: Automatically detects and adjusts to 7 listening environments including Speech in Loud Noise, Car, and Quiet — no manual program switching required

Sound & Noise Management

• Spheric Processing: Real-time 360-degree noise filtering that preserves speech clarity without sacrificing comfort
• Context-Aware Adaptation: Continuously analyzes the listening environment and adjusts amplification automatically as you move through your day
