The newest AI-powered hearing aids from Phonak and ReSound represent two distinct approaches to artificial intelligence in hearing technology. Phonak Infinio's dual-chip system focuses on comprehensive speech enhancement, while ReSound Vivia's Deep Neural Network prioritizes directional focus and natural sound processing.
Both manufacturers have invested heavily in AI technology, but their strategies differ significantly. Understanding these differences can help you choose the hearing aid that best matches your lifestyle and hearing needs.
Phonak Infinio's Dual-Chip Architecture
The Phonak Audéo Infinio Sphere stands out with its innovative dual-chip design. The ERA chip handles traditional sound processing and connectivity functions, while the dedicated DEEPSONIC chip focuses entirely on AI-powered speech separation. This separation allows the device to perform 7,700 million operations per second without compromising battery life or other features.
Phonak trained their AI system using 22 million sound samples, creating what they call Spheric Speech Clarity. This feature can provide up to 10 dB signal-to-noise ratio improvement, which translates to dramatically better speech understanding in challenging environments like restaurants, parties, or busy offices.
The AutoSense OS 6.0 automatically switches between different listening programs based on your acoustic environment. Whether you're in a quiet library or a crowded coffee shop, the system adapts without requiring manual adjustments.
SmartSpeech Technology includes several specialized features:
- Speech Enhancer improves clarity in quiet settings
- SpeechSensor detects when someone is speaking and optimizes accordingly
- StereoZoom 2.0 focuses on a single voice in noisy environments
- Dynamic Noise Cancellation reduces distracting background sounds
ReSound Vivia's Intelligent Focus Approach
ReSound takes a different approach with their Vivia hearing aids, using what they call human intelligence augmented by AI. The system was trained on 13.5 million spoken sentences across multiple languages, representing conversations that would take over 25 years to have in real life.
The Intelligent Focus feature works by prioritizing sounds based on where you're looking. This mimics the brain's natural tendency to focus on what captures our visual attention. When you turn to look at someone speaking, the AI automatically enhances their voice while reducing competing sounds from other directions.
ReSound's philosophy centers on keeping the user in control. Rather than having the AI make all decisions about what constitutes noise, the system learns from your behavior and preferences. This approach prevents the over-aggressive noise reduction that can sometimes eliminate sounds you actually want to hear, like the ambiance of a restaurant or children playing nearby.
The Deep Neural Network chip in Vivia performs 4.9 trillion operations per day and processes sound 17 times more efficiently than previous AI solutions. Internal research shows that 64% of users experience better speech comprehension in noise with Vivia compared to other AI-assisted hearing aids.
Battery Life and Charging Capabilities
Battery performance differs notably between these two systems. The Phonak Infinio provides up to 16-18 hours of use on a full charge, with multiple charging options including portable chargers with built-in power banks for travel.
ReSound Vivia offers impressive up to 30 hours of battery life on a single charge, or 20 hours when using both Intelligent Focus and audio streaming simultaneously. A 10-minute quick charge provides 2.7 hours of wearing time, making it convenient for users with busy schedules.
Both systems use lithium-ion rechargeable batteries and offer IP68 water and dust resistance ratings, the highest protection level available for hearing aids.
Connectivity and Smart Features
Both hearing aids feature Bluetooth 5.3 connectivity and can stream audio directly from smartphones, tablets, and televisions. They're compatible with both iOS and Android devices for hands-free calling and audio streaming.
Phonak Infinio includes RogerDirect technology, which allows connection to Roger wireless microphones without requiring additional receivers. This feature proves particularly valuable in classroom settings, business meetings, or other situations where you need to hear a speaker from across the room.
ReSound Vivia introduces Auracast technology, positioning it for the future of audio accessibility. Auracast will allow theaters, places of worship, airports, and other public venues to broadcast audio directly to compatible hearing aids. The ReSound Smart 3D app includes the world's first Auracast Assistant for hearing aids, simplifying the process of connecting to these broadcast streams.
Design and Discretion
Size and appearance matter to many hearing aid users. The ReSound Vivia microRIE is marketed as the world's smallest micro-receiver-in-ear hearing aid powered by AI. This compact design appeals to users who prioritize discretion.
Phonak Infinio Sphere measures 28.8 x 12.4 x 8.7 mm and weighs just 2.4 grams, making it similarly discreet. The standard Infinio R model is slightly larger but offers the same core features without the dual-chip architecture.
Both manufacturers offer multiple color options to match hair color and skin tone, with ReSound providing 10 choices including Navy Blue and Red, while Phonak offers various color combinations.
Real-World Performance Benefits
Clinical testing reveals different strengths for each system. Phonak reports up to 36.7% better speech understanding in complex environments and 45% reduction in listening effort for those with moderate to severe hearing loss. Users also report 21% less fatigue when the Speech Enhancer feature is active.
ReSound's research indicates that 83% of patients prefer the Intelligent Focus feature over previous-generation noise reduction technology. The directional focus approach helps users feel more connected to conversations without completely eliminating environmental awareness.
Making Your Choice
The decision between these AI systems often comes down to your primary listening challenges and lifestyle preferences. Phonak Infinio excels in extremely noisy environments where maximum speech separation is needed. The dual-chip architecture provides powerful processing while maintaining all-day battery life.
ReSound Vivia offers a more intuitive approach that works with your natural head movements and visual attention. The exceptional battery life and future-ready Auracast technology make it appealing for users who want the latest connectivity options.
Both systems require professional fitting and programming by an experienced audiologist. Real ear measurements during the fitting process ensure optimal performance by verifying that the hearing aid is providing the correct amount of amplification for your specific hearing loss.
