Phonak Infinio Hearing Aids

1. Introduction: Positioning in Phonak’s Ecosystem

Phonak Infinio, launched in 2024, is the next-generation hearing platform succeeding Lumity/Paradise. Its name reflects a philosophy of "limitless auditory access." Developed at Sonova’s Swiss engineering hub, Infinio prioritizes speech clarity in noise and universal connectivity. Key models: Audéo R (entry-level RIC), Audéo Sphere (AI-powered premium RIC), and CROS Infinio (for single-sided deafness).

2. Core Technologies & Innovations

Processor Architecture

  • DEEPSONIC™ AI Chip (Sphere models only): World’s first deep neural network (DNN) processor. Delivers 7.7 billion operations/sec – 53% more power vs. predecessors.

  • ERA Chip (All Infinio models): Bluetooth 5.3 supports pairing with 8 devices + dual-streaming. 2× extended wireless range vs. prior platforms.

Adaptive Sound Processing

  • Spheric Speech Clarity: Real-time speech-noise separation. Clinically verified 10 dB SNR improvement.

  • AutoSense OS 6.0: Adapts to environmental changes in 20 milliseconds. "Speech Sensor" auto-prioritizes human speech.

  • SoundRecover 2: Adaptively shifts high-frequency sounds to lower, audible frequencies.

Feedback Management

  • WhistleBlock Pro™: Blocks feedback while preserving natural whistle-like sounds (e.g., bird chirps).

  • ActiveVent: Dynamically adjusts ear canal pressure to reduce occlusion effect.

3. Target Hearing Loss Profiles & Fitting Range

  • Fitting Range: Mild to profound sensorineural hearing loss (25–100 dB HL).

  • Specialized Solutions:

    • CROS Infinio: Cross-hearing for single-sided deafness (SSD). 30% longer battery vs. previous CROS systems.

    • Tinnitus Balance: Integrated sound therapy for tinnitus relief.

  • Earmold AI Optimization: AI Dome Recommender software selects optimal venting based on audiograms.

  • Rapid Charging: 3 hours of use from a 15-minute charge.

  • Charging Systems:

    • ChargerGo RIC: Portable charging case with integrated power bank.

    • Magnetic Charging (Virto): Hassle-free alignment for dexterity-limited users.

6. Clinical Performance & User Experience

Clinical Data

  • Speech-in-Noise Understanding: 36.7% improvement in complex environments.

  • Reduced Listening Effort: 45% less effort in quiet; 34% less for speech from adjacent rooms.

  • Lower Fatigue: 21% less fatigue with Speech Enhancer active.

Global User Feedback

  • German Audiologist: "Sphere revolutionized dialogue tracking in busy restaurants."

  • Japanese User Survey: 89% satisfaction with Bluetooth stability.

  • Spanish Clinical Trial: 31% fewer repetitions during phone calls.

Real-World Test

An audiologist testing Infinio Sphere in a noisy restaurant noted:

"Background clatter was auto-suppressed. My companion’s voice sounded natural, as if I wore no hearing aids."
