The ReSound Vivia: A Revolutionary Leap in AI-Powered Hearing Technology

Redefining Hearing Aid Innovation

GN Hearing’s ReSound Vivia, launched on February 4, 2025, represents a seismic shift in hearing technology. Dubbed “the world’s smallest AI-powered hearing aid,” the Vivia combines cutting-edge artificial intelligence, advanced connectivity, and ergonomic design to deliver an unparalleled auditory experience 1, 7. This blog explores the Vivia’s groundbreaking features, its evolution from predecessors like the ReSound Nexia and Omnia, and its role in shaping the future of hearing accessibility.

The Evolution of ReSound Hearing Aids: From Omnia to Vivia

ReSound has long been a pioneer in hearing technology. The Omnia series, introduced in the early 2020s, set benchmarks with its 360° sound capture and dynamic noise reduction. Its successor, the ReSound Nexia, further refined these features with beamforming microphones and adaptive AI for situational awareness 2, 9. However, users still faced challenges in highly noisy environments, where traditional acoustic techniques—like directional microphones and noise filters—reached their limits.

The Nexia’s limitations underscored the need for a paradigm shift. Enter the ReSound Vivia, which replaces the Nexia as the flagship model. Unlike its predecessors, Vivia leverages a dedicated Deep Neural Network (DNN) chip trained on 13.5 million spoken sentences to separate speech from noise with surgical precision 1, 4. This marks a departure from reactive noise reduction to proactive, AI-driven sound enhancement—a leap comparable to transitioning from analog to digital hearing aids.

AI-Driven Innovation: The Heart of ReSound Vivia

1. Intelligent Focus: Mimicking the Human Brain

The Vivia’s standout feature is Intelligent Focus, a proprietary AI system that prioritizes sounds based on where the user is looking. By analyzing head and eye movements, the hearing aid dynamically amplifies voices in the user’s line of sight while suppressing background noise. This mimics the brain’s natural ability to focus on relevant sounds, creating a “seamless integration with the user’s perception of their environment” 1, 6.

In crowded settings like restaurants, this technology improves speech understanding by 64% compared to other AI hearing aids, according to GN’s clinical studies 7, 8. Users can activate “Beast Mode” via the ReSound app for extreme noise environments, combining Intelligent Focus with a 4-mic beamformer for maximum clarity 9.

2. Deep Neural Network (DNN) Chip: Powering Precision

At the core of Vivia’s AI is a custom DNN chip capable of 4.9 trillion operations per day. Trained across 3.9 million sound parameters, this chip is 17x more efficient than competing solutions, enabling real-time noise reduction without draining battery life 4, 10. The DNN’s training dataset includes multilingual speech samples, ensuring robust performance across diverse accents and vocal intensities 7.

3. Battery Life: All-Day Performance

Despite its computational power, the Vivia microRIE offers 30 hours of battery life on a single charge, or 20 hours with heavy streaming and Intelligent Focus usage 2, 6. This is a critical improvement over earlier models, addressing a common pain point for users reliant on continuous connectivity.

Auracast and Bluetooth LE Audio: A New Era of Connectivity

The Vivia and its sibling model, ReSound Savi, are among the first hearing aids to support Bluetooth LE Audio and Auracast™ broadcast technology. Auracast allows users to wirelessly stream audio from public venues—think airports, theaters, or conference halls—directly to their hearing aids 1, 10.

GN simplifies this with the ReSound Smart 3D™ app, which includes an Auracast Assistant for one-tap connectivity. Even devices without built-in Auracast support can leverage this feature, future-proofing the Vivia as the technology rolls out globally 6, 8. For Android and iPhone users, Bluetooth streaming remains seamless, with hands-free calling for iOS devices 2.

Design and Comfort: Small Size, Big Impact

The Vivia’s microRIE (Receiver-in-Ear) design is the smallest AI hearing aid on the market, weighing just 1.2 grams. Available in rechargeable and disposable battery options, it suits mild-to-severe hearing loss and includes CROS models for single-sided deafness 2, 10. Key design highlights:

• IP68 rating: Water and dust resistance, surviving submersion in 1 meter of water for 30 minutes 2.
• Customizable fit: Interchangeable receivers and domes, plus an app-based “Check My Fit” feature using smartphone cameras 2.
• Stylish options: Navy Blue, Red, and other colors to match personal style 7.

User-Centric Features: Beyond Hearing Enhancement

• Remote Care: Audiologists can adjust settings remotely post-fitting, reducing clinic visits 2.
• Tinnitus Relief: Customizable masking sounds via the ReSound Relief app 2.
• Find My Hearing Aid: GPS-enabled tracking for misplaced devices 2.

Impact on the Hearing Aid Industry

The Vivia’s launch signals a broader shift toward intelligence-augmented hearing, where AI complements—rather than replaces—human auditory processing. GN’s collaboration with hearing professionals has also led to improved fitting software and hygiene-friendly mic filters, streamlining clinical workflows 7, 10.

Looking ahead, GN envisions crowdsourced noise profiles, where users’ environmental data trains future DNN models, and continuous learning algorithms that adapt in real time 9. These innovations could further bridge the gap between natural and augmented hearing.

Conclusion: A New Standard for Hearing Technology

The ReSound Vivia is more than a hearing aid—it’s a gateway to richer human connection. By marrying AI’s computational prowess with intuitive design, GN has created a device that feels like an extension of the user’s senses. As Auracast adoption grows and AI evolves, the Vivia promises to remain at the forefront of auditory innovation, embodying GN’s mission to “bring people closer to what matters most” 7, 10.

For those seeking clarity in chaos, the Vivia isn’t just a tool; it’s a revolution.
