Resound Vivia vs. Resound Nexia Hearing Aids

ReSound Nexia Hearing Aids set a new benchmark when they arrived in late 2023. Compact, connected, and built for clarity, they made conversation in noise more natural than ever.

Now, the new ReSound Vivia takes that success further with Intelligence Augmented processing. Its Deep Neural Network was trained on real conversations to recognize voices and quiet the chaos around them—like a tiny sound engineer that never gets tired.

Hearing technology moves fast, and today’s devices feel light-years ahead of earlier models. You can discover the amazing features available in hearing aids today to see how innovations like adaptive focus, Bluetooth streaming, and AI-driven clarity have changed the game.

Next, let’s meet both models to see what sets them apart.

ReSound Nexia: Setting the Stage

When ReSound Nexia Hearing Aids launched in 2023, they brought an impressive mix of clarity and connectivity. The Nexia introduced Auracast-ready Bluetooth, a compact microRIE design, and ReSound’s 360 All-Around Directionality that helped listeners stay tuned into conversations from every angle. For many users, Nexia became the sweet spot between natural sound and effortless streaming.

ReSound Vivia: Intelligence Augmented for Real Life

Released in early 2025, the ReSound Vivia built on Nexia’s success with a smarter approach to sound. It added a second processing chip dedicated to running its Deep Neural Network—technology that listens, learns, and improves speech understanding in noise. The Vivia also delivered a new feature called Intelligent Focus, using microphone arrays to highlight the voice in front of you while keeping background sounds comfortable.

Although both models share ReSound’s proven comfort and Smart 3D app compatibility, the Vivia’s “Intelligence Augmented” design marks a real shift in how hearing aids handle noise. Next, we’ll explore what that Deep Neural Network actually does and why it matters for daily listening.

Understanding the Deep Neural Network (DNN)

The biggest leap between ReSound Vivia and ReSound Nexia Hearing Aids comes from one innovation: the Deep Neural Network, or DNN. This system is the brain behind Vivia’s Intelligence Augmented design, and it changes how hearing aids recognize and clarify speech in real life.

A deep neural network is a kind of artificial intelligence that learns through repetition—much like how people develop instincts by experience. Engineers at ReSound trained the DNN on millions of conversations recorded in homes, cafés, offices, and outdoor spaces. The network listened to how human speech differs from background noise, gradually teaching itself which sounds to highlight and which to soften.

That training allows the Vivia to respond in real time. Instead of applying fixed filters or preset programs, it constantly adapts its processing to match your surroundings. Whether you’re chatting in a quiet kitchen or ordering coffee in a crowded shop, the DNN decides what to prioritize without you needing to touch a button.

Here’s what this means for real-world listening:

• Smarter Noise Control: The DNN identifies voices almost instantly and keeps them clear even as background noise changes.

• Natural Sound Balance: Because it learned from real environments, it doesn’t overcorrect or make speech sound mechanical.

• Less Listening Effort: By focusing on speech automatically, the brain works less to follow conversations.

• Better Adaptability: The DNN improves with software updates, expanding its library of “listening experiences.”

Traditional digital signal processing, like that in Nexia, is still highly capable—it filters out steady noises and enhances speech in predictable ways. But Vivia’s dual-chip design lets the DNN run continuously without slowing the main processor, delivering faster, more lifelike adjustments that feel almost instinctive.

This Intelligence Augmented system is what separates Vivia from the crowd. Next, we’ll see how these differences translate into measurable advantages in everyday features and performance.

Side-by-Side Comparison: Feature Highlights

When comparing ReSound Nexia Hearing Aids with the newer ReSound Vivia, both deliver impressive sound quality, wireless performance, and comfort. The difference lies in how far Vivia pushes speech clarity and adaptability. Here’s how they stack up feature by feature.

Both models share ReSound’s signature natural sound and the convenient Smart 3D mobile app. The key difference lies in how they achieve clarity. Vivia’s Deep Neural Network processes sound dynamically, adapting moment by moment, while Nexia relies on proven but less flexible algorithms.

If you think of Nexia as a top-tier performer, Vivia feels like the same performer—after a few master classes in understanding conversation cues.

Up next, we’ll look at how that improved processing affects real-world battery life and performance throughout the day.

Battery Life and Daily Performance

Battery life may not sound exciting, but it determines whether your hearing aids keep up with your day. Both models offer excellent endurance, yet the Vivia’s second processor and refined battery system stretch performance further.

The microRIE version of the ReSound Nexia Hearing Aids typically delivers around 24 hours of use per charge, while the Vivia extends that to roughly 30 hours under similar conditions. The difference becomes more noticeable when you use streaming, AI features, or both heavily.

Battery Life Comparison for microRIE Models

Usage Scenario	ReSound Vivia	ReSound Nexia
Typical Daily Use	Up to 30 hours	Up to 24 hours
Heavy Streaming or AI Use	About 20 hours	About 20 hours
Continuous AI Use	As little as 10 hours	Not applicable

While both easily last through a full day, Vivia’s larger reserve means fewer recharge worries on travel days or during long events. Even better, both support fast charging and premium cases that store extra charges for life on the go.

In real-world terms, most users will recharge nightly and forget about battery anxiety altogether. What you’ll notice more often is how stable the sound stays as the charge drops—a strength of ReSound’s dual-processor design.

Next, let’s see how that power translates into real-world listening comfort, clarity, and confidence in everyday environments.

Real-Life Listening: Noise, Speech, and Comfort

The biggest reason people upgrade hearing aids is simple: they want to understand voices better in noise. Both the ReSound Vivia and ReSound Nexia Hearing Aids were designed to solve that challenge—but they take slightly different approaches.

Hearing in Noisy Places

Vivia’s Intelligent Focus feature combines its Deep Neural Network with a four-microphone system that locks onto the speaker in front of you. The system automatically reduces background chatter without flattening the natural ambiance around you. In restaurants or family gatherings, voices stay sharp while laughter and clinking dishes fade into the background.

Nexia also performs impressively here, using its 360 All-Around Directionality to sense where speech is coming from and adjust microphone focus accordingly. It doesn’t use a neural network but still provides a remarkably natural, balanced soundscape that keeps you engaged in conversation.

Speech Clarity and Directionality

Where Nexia relies on pattern-based sound processing, Vivia’s DNN learns from real-world listening. This means faster adaptation when the environment changes—like stepping from a quiet lobby into a noisy street. The transition feels smooth and automatic. Users who switch between different listening spaces during the day often notice this subtle improvement first.

For perspective, ReSound’s AI approach differs from how other brands manage background noise. Our comparison of ReSound Vivia vs. Starkey Edge AI shows how Vivia’s Intelligence Augmented system focuses on learning from real sounds rather than relying solely on fixed presets.

Comfort and Fit

Both models share the same ergonomic microRIE shape, known for its secure yet discreet feel. The lightweight design works well for glasses wearers and those sensitive to pressure behind the ear. Thanks to the Smart 3D app, users can fine-tune settings anytime, making on-the-go adjustments easy and intuitive.

The combination of natural directionality, adaptive focus, and personalized control makes everyday listening feel less like “work.” That effortless experience continues into their next major strength—wireless connectivity and Auracast streaming.

Connectivity and Auracast: Ready for the Future

Both ReSound Vivia and ReSound Nexia Hearing Aids were built for seamless streaming. They use Bluetooth Low Energy (LE) Audio to deliver clearer, lower-power connections and allow direct streaming from most modern smartphones. That means you can take calls, listen to music, or watch TV without bulky adapters or dongles.

Where Vivia stands apart is its full Auracast compatibility. Auracast is a next-generation broadcast system that lets hearing aids connect directly to shared public audio—like announcements in airports or the soundtrack in a theater. Nexia was “Auracast-ready” when released, meaning it could support the feature once venues and devices adopted the standard. Vivia arrives fully prepared from day one.

You can learn more about how hearing aids with Bluetooth can use Auracast to stay connected wherever you go. These technologies do more than add convenience; they make hearing aids part of a much larger accessibility movement.

Here’s what users appreciate most:

• Hands-Free Calls: Stream calls directly through both aids with built-in microphones.
